• Tracking down rogue disk usage

  - by Amadan

  I found several other questions regarding the theory behind my problem (e.g. this, this), but I don't know how to apply the answers to my machine. # du -hsx / 11000283 / # df -kT / Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/csisv13-root ext4 516032952 361387456 128432532 74% / There is a big difference between 11G (du) and 345G (df). Where are the remaining 334G? It's not in deleted files. There was only one, it was short, and I truncated it just in case. This is what remains: # lsof -a +L1 / COMMAND PID USER FD TYPE DEVICE SIZE/OFF NLINK NODE NAME zabbix_ag 4902 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4902 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4906 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4906 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4907 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4907 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4908 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4908 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4909 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4909 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4910 zabbix 1w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) zabbix_ag 4910 zabbix 2w REG 252,0 0 0 28836028 /var/log/zabbix-agent/zabbix_agentd.log.1 (deleted) I rebooted to see if fsck does anything.

• Exchange 2007 Standard Edition

  - by Phrontiste

  We Have : Exchange 2007 Standard Edition IBM System X3650 2 x Intel Xeon 5430 2.66 GHz Version 8.1 Build 240.6 Mailbox, Hub Transport, Client Access Role Installed on One Box Total Number of Mailboxes : 110 - 130 6 Physical Disks Disk 0,1 (68 GB) = Raid-1, OS Partition ( C: Partition) Disk 2,3 (279GB) = Raid-1, Exchange Database (First and Second Storage Groups) ( D: Partition ) Disk 4,5 (68 GB) = Raid-1, Exchange Transaction Logs ( E: Partition ) Setup: Storage Groups : D:\First Storage group\Mailbox database.edb Storage Groups : D:\Second Storage Group\Public Folder Database.edb Transaction Logs : E Partition Problem 1: On our D Partition (Mailbox Database Partition), total size is 279 GB, free space remaining is 64.7 GB, when I select the first storage group and second storage group folders and right click properties they report a size of 165 GB. Mailbox database reports a size of 157GB when right clicked Properties. where as the size displayed in the folder is 164,893,456 KB So, we are missing around 50-54 GB, there is nothing else on these drives, no page file, nothing at all. The partition housing the Transaction logs is reporting the sizes accurately. Any suggestions / fixes on the above ? Problem 2: As you may have already read in Problem 1, the size of the mailbox database is 157GB or 164GB reported; which is not recommended, a) What would you suggest we should do to divide mailboxes in storage groups on this same server ? b) How would we move mailboxes into different storage groups ? c) This is the information store size ? (Am I right in thinking that this is not recommended) d) Having multiple storage groups with one Mailbox DB in each, would that reduce the size of the Information Store? e) Any suggestions / how-to reduce the size of information store ? We didn't install this, we have inherited this - what other recommendations you can make in order to keep ourselves better prepared for any server disaster? We are backing up with Yosemite Backup on RD1000 (320GB) at the moment, which is backing up successfully, flushing the logs daily. We haven't done a test restore YET. I have tried to provide as much info as possible, please let me know if you need further info. Also, we haven't yet faced any problems in mailflow, access speeds, everything is working fine, we have two to five people accessing OWA or Outlook via vpn only. Thanks for your time to read the above - will look forward to your expert suggestions.

• How to reset mysql's replication settings completely, without reinstalling it?

  - by user38060

  I set up mysql replication by adding references to binlogs, relay logs etc in my.cnf restarted mysql, it worked. I wanted to change it so I deleted all binlog related files including log-bin.index, removed binlog statements from my.cnf restarted server, works set master to '', purge master logs since now(), reset slave, stop slave, stop master. now, to set up replication again, I added binlog statements to the server. But then I hit this problem when restarting with: sudo mysqld (the only way to see mysql's startup errors) I get this error: /usr/sbin/mysqld: File '/etc/mysql/var/log-bin.index' not found (Errcode: 13) Because indeed, this file does not exist! (I deleted it, while trying to set up a new replication system) Hmm, if I change the config line to: log-bin-index = log-bin.index I get a different error: [ERROR] Can't generate a unique log-filename /etc/mysql/var/bin.(1-999) [ERROR] MSYQL_BIN_LOG::open failed to generate new file name. [ERROR] Aborting The first time I set up replication on this system, I didn't need to create this file. I did the same thing - added references to a previously non-existing file, and mysql created it. Same with relay logs, etc. I don't know why mysql insists on trying to read the old folder. Should I just reinstall the whole package again? That seems like overkill. my my.cnf: [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] user = mysql socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp skip-external-locking bind-address = IP key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 myisam-recover = BACKUP table_cache = 64 sort_buffer =64K net_buffer_length =2K query_cache_limit = 1M query_cache_size = 16M slow_query_log_file = /etc/mysql/var/mysql-slow.log long_query_time = 1 log-queries-not-using-indexes expire_logs_days = 10 max_binlog_size = 100M server-id = 3 log-bin = /etc/mysql/var/bin.log log-slave-updates log-bin-index = /etc/mysql/var/log-bin.index log-error = /etc/mysql/var/error.log relay-log = /etc/mysql/var/relay.log relay-log-info-file = /etc/mysql/var/relay-log.info relay-log-index = /etc/mysql/var/relay-log.index auto_increment_increment = 10 auto_increment_offset = 3 master-host = HOST master-user = USER master-password=PWD replicate-do-db = DBNAME collation_server=utf8_unicode_ci character_set_server=utf8 skip-character-set-client-handshake [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash [myisamchk] key_buffer_size = 16M sort_buffer_size = 8M [mysqlhotcopy] interactive-timeout !includedir /etc/mysql/conf.d/ Update: Changing all the /etc/mysql/var/xxx paths in binlog & relay log statements to local has somehow solved the problem. I thought it was apparmor causing it at first, but when I added /etc/mysql/* rw, to apparmor's config and restarted it, it still couldn't read the full path.

• Small Business Server services will not start, and remote desktop and UAC are broken

  - by Stephen Jennings

  Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

• Remove DRM from *.pdb e-book that I own - while maintaining footnotes, etc.?

  - by ziesemer

  Background: I've already reviewed Remove DRM from ePub Files? and How can I remove DRM from Kindle books? - the answers to which have already brought me partial process. The challenge is that I have a few purchased *.pdb e-books that I purchased in years past, e.g. 2006. In particular, they were purchased from the palm eBook Store (ebooks.palm.com - now defunct, possibly part of http://www.ereader.com / Barnes & Noble?) - originally for use on a Palm Treo that has since died. Of particular note is that I have a revision / publication of a book that is no longer published, and not available as an e-book from anywhere else that I've been able to find. (I feel fortunate to have even found the *.pdb files on backup.) I have a copy of the electronic invoice for it - which includes the details necessary for unlocking - the "Purchaser's Name" and the "Unlock Code" - which is the digits of my credit card # that I had used to purchase it. Given the above information, I was surprised to be able to open the book using the Windows eReader software and unlock it. Here I am able to view the complete contents and functionality of the book as I had done on the Palm Treo - including viewing of linked annotations / footnotes, etc. Following the full spirit of Remove DRM from ePub Files?, I want to ensure that I can access this on any device of my choosing - especially now and in the future, and as new technologies arrive and disappear. Ideally, I'm just looking to accomplish the minimum necessary to allow import into calibre. Outstanding Issue: I've found a few solutions that have given me "90%" success - all based on various versions of some Python scripts - including versions 0.21 and 0.11 of "erdr2pml.py" (based on "ereader2html"). Unfortunately, unless I'm missing something, these programs are attempting to also "convert" - instead of just "decrypting". As such, the outputs are missing embedded images and/or footnotes. I.E., there is a linked, underlined, and super-scripted "a" after some text - but the content of the footnote no longer exists. I can validate this by inspecting the generated *.pmlz file, and nowhere does it contain the original footnotes that are still visible in the original *.pdb file. I'm hoping to find a process that focuses on the decryption only, instead of attempting any type of a content conversion - or if a content conversion is required / involved, that it maintains all of the features and content of the original. (Again, I'm confident that if/once a version is obtained that calibre can import, I'll be able to fulfill the rest of my requirements.)

• how to diagnosis and resolve: /usr/lib64/libz.so.1: no version information available

  - by matchew

  I had a hell of a time installing lxml for python2.7 on centOs5.6. For some background, python2.7 is an alternative installation of python on centOS5.6 which comes with python2.4 installed. it was bulit from source per its instrucitons ./configure make make altinstall However, after about 20 hours of trying I managed to find a workable solution and was able to install lxml. Until, I notice the following error at the top of the interpreter: python2.7: /usr/lib64/libz.so.1: no version information available (required by python2.7) Python 2.7.2 (default, Jun 30 2011, 18:55:26) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> print 'Sheeeeut!' this error is printed out everytime I run a script. For example: $ ./test.py /usr/local/bin/python2.7: /usr/lib64/libz.so.1: no version information available (required by /usr/local/bin/python2.7) the script runs flawlessly, but this error is bothersome. After some digging I have seem to believe I have a wrong version of libz installed, that it is either an older version or built for a different platform. I'm not quite sure how, I've only installed libz through yum, as far as I know. Although, I can't quite remember every little thing I tried in my twenty hours of trying. You may also be intereted in what my lib64 folder looks like, here is some information $ ls -ltrh libz* -rwxr-xr-x 1 root root 84K Jan 9 2007 libz.so.1.2.3 -rwxr-xr-x 1 root root 107K Jan 9 2007 libz.a -rwxr-xr-x 1 root root 154K Feb 22 23:30 libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Apr 20 20:46 libz.so.1 -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jun 30 18:43 libzdb.so.7 -> libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Jul 1 11:35 libz.so -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jul 1 11:35 libzdb.so -> libzdb.so.7.0.2 notice: the items that Say Jul 1st or Jun 30th are from me. I had initially moved these files into a backup folder as they seeemed to be 1. duplicates and 2. had a date after/during my problems I alluded to earlier that I had with lxml One inclination is to completely remove python2.7 and re-install. I think having it install to /usr/local/ was a poor default choice. However, without the make uninstall option being present it seems to be a time consuming task for a solution I am not quite sure would solve my problem.

• Fast user switching suddenly stopped working on my Windows XP Prof machine

  - by John

  When I start Win XP SP2 I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups is listed. I did a windows repair with no luck. I tried doing restore points but it said they didn’t work. Please help? My wife and I have been using fast user switching on out computer for years with no problem. Beginning a few months ago, I started Win XP Prof one day I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows with an account of owner. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups are listed. I have done system point restores and imports of exports of the registry I take with import. I have tried everything under safe mode and it makes no difference. This followed a Microsoft update the night before as I left the computer on. I tried to do a restore point but all my restore points failed and could not backout the MS updates. I was working with a fellow from Microsoft and he had me do all kinds of things but to no avail. He seems to think a DLL file is corrupt but which one? Finally in desperation he sent me a new OS XP Prof SP3 disk and I installed it and it wiped my hard drive. Luckily I took an Acronis Image backup first so I easily restored my system. I do not want to do a fresh windows update as it is heavily customized and worked fine up to that point. This has been going on for months, Thanks John

• APC ups es 700 randomly overload

  - by Matteo Mosca

  First of all, I live in Italy, Europe, so keep this in mind for Volt/Watt considerations. Standard voltage in Italian apartments is 220V. In my living room I have 2 APC ups, one being an ES-550 and the other an ES-700 They each have 4 slots for surge protection only, and 4 slots for surge protection + battery backup. Just to give all the information, they both got their battery replaced less than one month ago. The ES-550 works fine, without any problem. On the battery I have connected: Pc Monitor Sony Bravia 46'' 4th slot is empty The ES-700 has the following on battery: Xbox 360 Ps3 (standby when not used) Wii (standby when not used) Netgear 8 port switch (always on) Here's what happens: the ES-700, randomly, but mostly at night when I'm sleeping, goes like "overload", with the constant beep. If I try to shut it off keeping the power button pressed, nothing happens. The only thing that works is unplugging random stuff (sometimes unplugging 1 console works, other times I have to unplug all 4 devices). Every time this happens the problem is "real", meaning the 4 devices become unpowered, so it's not just an "alarm no working properly" problem. While I'm sleeping, of course, the power usage is what described on the list, 2 devices on standy, 1 off and 1 on. Today it happened again while I was playing with my Ps3. I unplugged it, problem went away. I plugged it again, and it kept working fine. I just can't figure out what's the problem. The only additional info I can provide is that this behaviour started after a big power outage last december 26 (a blackout that lasted almost all day) but the "surge protection" part of those UPS should be there for those problems, to leverage peaks when power goes away or gets restored. Another funny thing is, althought it might not be related, for a couple of days after that event the Wii was unable to power on, I thought its power transformer was broken, but then it suddenly started working again. I can be sure it's not the Wii overloading the UPS because the overload happens even if I leave the Wii unplugged. Any suggestion is really appreciated, and I can provide any additional info, if needed, that didn't come to mind right now. Thanks.

• Hang while starting several daemons [solved]

  - by Adrian Lang

  I’m running a Debian Squeeze AMD64 server. Target runlevel after boot is runlevel 2, which includes rsyslogd, cron, sshd and some other stuff, but not dovecot, postfix, apache2, etc. The system fails to reach runlevel 2 with several symptoms: The system hangs at trying to start rsyslogd Booting into runlevel 1 works, then login from the console works Starting rsyslogd from runlevel 1 via /etc/init.d/rsyslog hangs Starting runlevel 2 with rsyslogd disabled works But then, logging in via console fails: I get the motd, and then nothing Starting sshd from runlevel 1 succeeds But then, I cannot login via ssh. Sometimes password ssh login gives me the motd and then nothing, sometimes not even this. Trying to offer a public key seems to annoy the sshd enough to not talk to me any further. When rebooting from runlevel 1, the server hangs at trying to stop apache2 (which is not running, so this really should be trivial). Trying to stop apache2 when logged in in runleve 1 does hang as well. And that’s just the stuff which fails all the time. RAM has been tested, dmesg shows no problems. I have no clue. Update: (shortened) output from rsyslogd -c4 -d called in runlevel 1 rsyslogd 4.6.4 startup, compatibility mode 4, module path '' caller requested object 'net', not found (iRet -3003) Requested to load module 'lmnet' loading module '/user/lib/rsyslog/lmnet.so' module of type 2 being loaded conf.c requested ref for 'lmnet', refcount 1 rsylog runtime initialized, version 4.6.4, current users 1 syslogd.c requested ref for 'lmnet', refcount now 2 I can kill rsyslogd with Strg+C, then. /var/log shows none of the configured log files, though. Update2: Thanks to @DerfK I still have no clue, but at least I narrowed down the problem. I’m now testing with /etc/init.d/apache2 stop (without an apache2 running, of course) which hangs as well and looks like an even more obvious failure. After some testing I found out that a file with one single line: /usr/sbin/apache2ctl configtest /dev/null 2&1 hangs, while the same line executed in an interactive shell works. I was not able to further reduce this line while, i. e. every single part, the stream redirections and the commando itself is necessary to reproduce the hang. @DerfK also pointed me to strace which gave a shallow hint about what kind of hang we have here: wait4(-1for the init scripts futex(0xsomepointer, FUTEX_WAIT_PRIVATE, 2, NULL for rsyslogd / apache2 binaries called by the init scripts The system was installed as a Debian Lenny by my hoster in autumn 2011, I upgraded it to Squeeze immediately and kept it up to date with Squeeze, which then used to be testing. There were no big changes, though. I guess I never tried to reboot the system before. Update3: I found the problem. My /etc/nsswitch.conf specified ldap as hosts lookup backup, which is not available at that time of the boot. Relying on dns solely fixes my boot problems.

• Baseline / Benchmark Physical and virtual server performance

  - by EyeonTech

  I am setting up a new server and there are some options. I want to perform some benchmarks and I need your help in determining the best tools and if possible run pre-configured benchmarks designed for SQL servers on Windows Server 2008/2012. Step 1. Run a performance monitor on the current Live SQL server (Windows Server 2008 Virtual machine running on ESXi. New server Hardware rundown: Intel® Server System R1304BTLSHBN - 1U Rack, LGA1155 http://ark.intel.com/products/53559/Intel-Server-System-R1304BTLSHBN Intel Xeon E3-1270V2 2x Intel SSD 330 Series 240GB 2.5in SATA 6Gb/s 25nm 1x WD 2TB WD2002FAEX 2TB 64M SATA3 CAVIAR BLACK 4x 8GB 1333MHz DDR3 ECC CL9 DIMM There are several options for configurations and I want to benchmark some of them and share the results. Option 1. Configure 2x SSDs at RAID 0. Install Windows Server 2008 directly to the 2TB WD Caviar HDD. Store Database files on the RAID 0 Volume. Benchmark the OS direct on the hardware as an SQL Server. Store SQL Backup databases on the 2TB WD Caviar HDD. Option 2. Configure 2x SSDs at RAID 0. Install Windows Server 2012 directly to the 2TB WD Caviar HDD. Install Hyper-V. Install the SQL Server (Server 2008) as a virtual machine. Store the Virtual Hard Disks on the SSDs. Option 3. Configure 2x SSDs at RAID 0. Install VMWare ESXi on a partition of the 2TB WD Caviar HDD. Install the SQL Server (Server 2008) as a virtual machine. Store the Virtual Hard Disks on the SSDs. I have a few tools in mind from http://technet.microsoft.com/en-us/library/cc768530(v=bts.10).aspx. Any tools with pre-configured test would be fantastic. Specifically if there are pre-configured perfmon sets avaliable. Any opinions on the setup to gain the best results is welcome. Thanks in advance.

• mounting ext4 fs with block size of 65536

  - by seaquest

  I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I can not mount it on ubuntu-10.10-netbook-i386.

• Partition table corrupted (USB flash drive)

  - by 13ren

  It's an 8 GB Patriot thumb drive, which I've used extensively with lots of data. Today, it is detected, but all data is gone: (EDIT at least some data is still there, but the partition table is gone) EDIT @Sathya (thanks) here's the relevant output from sudo fdisk -l: Disk /dev/sdc: 8019 MB, 8019509248 bytes 247 heads, 62 sectors/track, 1022 cylinders Units = cylinders of 15314 * 512 = 7840768 bytes Disk /dev/sdc doesn't contain a valid partition table It looks like it is /dev/sdc, with that 8 GB... and no partition table.

Keys A: add partition, L: load backup, Enter: to continue The "Structure: Ok." seems reassuring... will "A: add partition" make my old data accessible (if it's still there), or will it make a new, fresh partition? Another option is "[ MBR Code ] Write TestDisk MBR code to first sector" - would it be better to do this? EDIT I found that at least some of my data is still on the flash drive, by using the below, and searching for English text in less (like " the "): cat /dev/sde | tr -cd '\11\12\40\1540-\176' | less (The drive changed from "/dev/sdb" to "/dev/sde" because I connected some extra drives today). I've learnt that "/dev/sde1" would be the first partition; and "/dev/sde" is the whole drive. Because unix treats these devices just like files, you can use all the ordinary unix file commands on them, like cat, and then process them like any other stream of data. The tr above removes non-printable characters ("\40" is space, which I wanted to preserve). In less, you can use "/" to search, similar to Vim. How can I get my data back (assuming it's still there)? If only the partition table is corrupted, is there a standard "partition recovery tool"? Is there a way to "repartition" without deleting everything?

• HAproxy roundrobin balancing does not appear to be distributing evently

  - by andrew

  Hello, I know that with loaded servers, roundrobin in HAproxy (1.4.4) does not evenly distribute, but my servers are currently getting NO traffic (test setup), and roundrobin balancing does www1,www1,www1,www1,www1,...www2,www2,www2,...,www1... I'm verifying this by having the script being run on each server cat /etc/HOSTNAME (slackware). I need to have it switch back and forth each time to test some session stuff (stored in shared memcached) but am having trouble getting it to switch between my two web servers on each request. global log 127.0.0.1 local0 warning maxconn 4096 chroot /usr/share/haproxy pidfile /var/run/haproxy.pid uid 99 gid 99 daemon defaults balance roundrobin fullconn 100 maxconn 4096 mode http option dontlognull option http-server-close option forwardfor option redispatch retries 3 timeout connect 5000 timeout client 20000 timeout server 60000 timeout queue 60000 stats enable stats uri /haproxy stats auth ***:*** frontend www *:80 log global acl is_upload hdr_dom(host) -i uploads.site.com acl is_api hdr_dom(host) -i api.site.com acl is_dev hdr_dom(host) -i dev.site.com acl is_apidev hdr_dom(host) -i apidev.site.com use_backend uploads.site.com if is_upload use_backend api.site.com if is_api use_backend dev.site.com if is_dev !is_apidev default_backend site.com backend site.com option httpchk HEAD /alive.php HTTP/1.1\r\nHost:site.com server www1 1.1.1.1:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 server www2 1.1.1.2:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 backend api.site.com option httpchk HEAD /alive.php HTTP/1.1\r\nHost:api.site.com server www1 1.1.1.1:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 server www2 1.1.1.2:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 backend dev.site.com option httpchk HEAD /alive.php HTTP/1.1\r\nHost:dev.site.com server www1 1.1.1.1:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 server www2 1.1.1.2:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 backend uploads.site.com option httpchk HEAD /alive.php HTTP/1.1\r\nHost:uploads.site.com server www1 1.1.1.1:8080 weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 server www2 1.1.1.2:8080 backup weight 10 minconn 5 maxconn 25 check inter 2000 rise 2 fall 2 So basically, I have some different back-ends (I've verified the ACLs are working), with the default option "roundrobin" selected. I've tried removing weights, removing the minconn/maxconn/fullconn attributes for all servers (not just the backend I'm testing), tried removing the ACLs, etc. I've been testing on dev.site.com BTW. Anyone see a reason why I can't get something like www1,www2,www1,www2,...? Also, this is one of my first questions on here, so please let me know if I left anything needed out of my post. Thanks!

• Generating/managing config files for hosted application

  - by mfinni

  I asked a question about config management, and haven't seen a reply. It's possible my question was too vague, so let's get down to brass tacks. Here's the process we follow when onboarding a new customer instance into our hosted application : how would you manage this? I'm leaning towards a Perl script to populate templates to generate shell scripts, config files, XML config files, etc. Looking briefly at CFengine and Chef, it seems like they're not going to reduce the amount of work, because I'd still have to manually specify all of the changes/edits within the tool. Doesn't seem to be much of a gain over touching the config files directly. We add a stanza to the main config file for the core (3rd-party) application. This stanza has values that defines the instance (customer) name the TCP listener port for this instance (not one currently used) the DB2 database name (serial numeric identifier, already exists, they get prestaged for us by the DBAs) three sub-config files, by name - they need to be created from 3 templates and be named after the instance The sub-config files define: The filepath for the DB2 volumes The filepath for the storage of objects The filepath for just one of the DB2 volumes (yes, redundant to the first item. We run some application commands, start the instance We do some LDAP thingies (make an OU for the instance, etc.) We add a stanza to the config file for our security listener that acts as a passthrough to LDAP instance name LDAP OU TCP port for instance DB2 database name We restart the security listener (off-hours), change the main config file from item 1, stop and restart the instance. It is now authenticating via LDAP. We add the stop and start commands for this instance to the HA failover scripts. We import an XML config file into the instance that defines things for the actual application for the customer - user names, groups, permissions, and business rules. The XML is supplied by the implementation team. Now, we configure the dataloading application We add a stanza to the existing top-level config file that points to a new customer-level config file. The new customer-level config file includes: the instance (customer) name the DB2 database name arbitrary number of sub-config files, by name Each of the sub-config files defines: filepaths to the directories for ingestion, feedback, backup, and failure those filepaths have a common path to a customer-specific folder, and then one folder for each sub-config file Each of those filepaths needs to be created We need to add this customer instance to our monitoring scripts that confirm the proper processes are running and can be logged into. Of course, those monitoring config files include the instance name, the TCP port, the DB2 database name, etc. There's also a reporting application that needs to be configured for the new instance. You get the idea. There's also XML that is loaded into WAS by the middleware team. We give them the values for them to plug into the XML - they could very easily hand us the template and we could give them back completed XML.

• Missing startup screens and slow bootup/login after using WinClone to expand Bootcamp partition

  - by user26453

  I used WinClone to backup my Bootcamp partition, which was a Windows 7 Ultimate install, on my late 2006 Macbook Pro. I desired to expand the Bootcamp partition's size. It worked reasonably well with some hiccups along the way and some remaining issues. First issue I ran into was the Bootcamp Assistant utility - it would not recreate the partition. This was due to a lack of contiguous space that is required for the Bootcamp partition. As a result I wiped the whole drive and reinstalled Snow Leopard, did the minimum amount of system updates, and created and formated a new Bootcamp partition. WinClone restored the image without complaint and the image was automatically resized to the new partition's size. Second issue I ran into was after the first boot into Windows. The first thing I noticed was that instead of the newer "slick" startup screen (4 colors wisping around, a Windows 7 title), there was more of an old school style startup screen (a progress bar with block increments, yellow/greenish color, nothing else really). The initial bootup to a login screen was slow, perhaps as Windows dealt with the partition changes. After logging in, the screen goes blank and the computer seems to hang for a minute, before completing the login. After subsequent restarts, the slick screen is still missing, boot to login screen is normal, but the time from login to desktop active is still very slow. As a side note, this behavior of a long time from login to the desktop finally loaded I've previously only seen when the computer would try to hibernate and fail (battery is really bad). On the next startup, I would see this behavior, but not subsequently. So a potential cause: I imaged the partition after hibernating out of Windows. From reading some posts/guides on the subject, this was not recommended, and perhaps shouldn't even have worked? Could the partition be stuck in some weird mode as a result that makes the boot issues appear? I've attempted to disable hibernation and restart, trying to delete the .sys file that hibernation uses. Other fixes I'm thinking of attempting are booting a Win7 disc and repairing the install/partition. I can't shake the nagging feeling something isn't right as a result of the modified boot screens and the slow login process.

• What is it that kills laptop batteries?

  - by Mala

  There are many superstitions on what you must never do lest your battery become worthless - and by worthless I mean hold about 16 - 24 seconds of charge. This has happened to every laptop I have ever owned, and I just got a new one, so please help me sort out fact from fiction. Here are some of the things I've heard: Do not keep your laptop fully charged. You must run it completely down every so often. Do not use your laptop plugged in to the wall. Only plug it in when it needs charge. If you will not be using your laptop for a long period of time, don't leave it at full charge. Do not leave your laptop running 24/7. The first two I know to be complete fiction: this was true of old batteries such as you might have had in an iPod in 2003, but modern batteries function better when kept at or near full charge. Devices even have circuitry to prevent you from completely depleting your battery, as this is dangerous. The third point sounds probable, and I'd be interested to know if it was true. However, it doesn't really apply to me because I'm not really the type to leave my laptop alone for a day, much less a "long period of time" The fourth seems most likely of the above, but only because of causality: I have always done this, and my batteries have always crapped out on me. I've generally treated a laptop like a desktop with a battery backup, and that I can move from one room to another if necessary. The fact that my batteries tend to last less than 30 seconds has further entrenched this behavior. Should I be trying to break this habit? Are there any other things that ruin laptop batteries? I love that I can actually use my new laptop unplugged :) I'd like to keep it that way. Update: Additional question: If the computer will be used for an extended period of time plugged in, does it make sense to remove the battery first? Update 2: I know people with laptops older than mine, who actively use their laptops as much as I do, and their batteries still hold about an hours' charge while mine holds less than 30 seconds, hence my belief that something I'm doing kills them.

• Active Directory Corrupted In Windows Small Business Server 2011 - Server No Longer Domain Controller

  - by ThinkerIV

  I have a rather bad problem with my Windows SBS 2011. First of all, I'll give the background to what caused the problem. I was setting up a new small business server network. I had my job about finished. The server was working great, all the workstations had joined the domain, and I had all my applications and data moved to the server. I thought I was done. But then it happened. I tried adding one more computer to the domain, and to my dismay the computer name was set to the same name as the server. Apparently when a computer joins a domain with the same name as another machine that is already on the domain, it overrides the first one. For normal workstations, this is not a big deal, you just delete the computer from AD and rejoin the original computer to the domain. However, for a server that is the domain controller it is a whole different story. Since the server got overridden in AD, it is no longer the domain controller. The DNS service is not working and all kinds of other services are failing also. So the question is, what are my options? I am embarrassed to admit it, but since this is a new server one thing I did not have setup yet was backup. So I have no backups to work from. I am worried that things are broken enough that I might need to do a reinstall. However, I already have several days worth of configuration into this server, so I would obviously prefer if there was a fix that would prevent me from needing to do a reinstall. All the server components are there and installed correctly, but they are misconfigured (I think it is basically just Active Directory). So I have the feeling that if I did the right thing I could solve the issue without a reinstall. Is there anyway to rerun the component that installs the initial configuration to "convert" the base windows server 2008 r2 install into a SBS? In other words in the program files folder there is an application called SBSsetup.exe, is there anyway to rerun this and have it reconfigure AD, etc. to work with SBS? Any insight will be greatly appreciated. Thanks.

• What part of SMF is likely broken by a hard power down?

  - by David Mackintosh

  At one of my customer sites, the local guy shut down their local Solaris 10 x86 server, pulled the power inputs, moved it, and now it won’t start properly. It boots and then presents a prompt which lets you log in. This appears to be single user milestone (or equivalent). Digging into it, I think that SMF isn’t permitting the system to go multi-user. SMF was generating a ton of errors on autofs, after some fooling with it I got it to generate errors on inetd and nfs/client instead. This all tells me that the problem is in some SMF state file or database that needs to be fixed/deleted/recreated or something, but I don’t know what the actual issue is. By “generate errors”, I mean that every second I get a message on the console saying “Method or service exit timed out. Killing contract <#.” This makes interacting with the computer difficult. Running svcs –xv shows the service as “enabled”, in state “disabled”, reason “Start method is running”. Fooling with svcadm on the service does nothing, except confirm that the service is not in a Maintenance state. Logs in /lib/svc/log/$SERVICE just tell you that this loop has been happening once per second. Logs in /etc/svc/volatile/$SERVICE confirm that at boot the service is attempted to start, and immediately stopped, no further entries. Note that system-log isn’t starting because system-log depends on autofs so I have no syslog or dmesg. Googling all these terms ends up telling me how to debug/fix either autofs or nfs/client or inetd or rpc/gss (which was the dependency that SMF was using as an excuse to prevent nfs/client from “starting”, it was claiming that rpc/gss was “undefined” which is incorrect since this all used to work. I re-enabled it with inetadm, but inetd still won’t start properly). But I think that the problem is SMF in general, not the individual services. Doing a restore_repository to the “manifest_import” does nothing to improve, or even detectibly change, the situation. I didn’t use a boot backup because the last boot(s) were not useful. I have told the customer that since the valuable data directories are on a separate file system (which fsck’s as clean so it is intact) we could just re-install solaris 10 on the / partition. But that seems like an awfully windows-like solution to inflict on this problem. So. Any ideas what piece is broken and how I might fix it?

• Impact of the L3 cache on performance - worth a dual-processor system?

  - by Dan Nissenbaum

  I will be purchasing a new high-end system, and I would like to have a better sense of whether a dual-processor Xeon system (I am looking at the new, high-end Xeon E5-2687W) might, realistically, provide a noticeable performance improvement due to the doubling of the L3 cache (20 MB per CPU). (This is in addition to the occasional added advantage due to the doubling of cores and RAM.) My usage scenario is, roughly, that I have many background applications running at any time - 3 or 4 data compression/backup applications, a low-impact web server, one or two virtual machines at any given time (usually fairly idle), and perhaps 20 utility programs that utilize a noticeable (but small) portion of the CPU cores. In total, when I am not actively using the computer, about 25% of the total CPU power is utilized in my current i7-970 6-core (12 thread) system. When I am doing routine work, the CPU utilization often exceeds 50%, and occasionally hits 75%-80%. The Xeon E5-2687W is not only a second-generation i7 (so should improve performance for that reason), but also has 8 cores (16 threads), rather than 6 cores. For this reason, I expect to run into the 75% CPU range even less frequently. Nonetheless, the ability to double the cores and the RAM is a consideration. However, in the end, I believe this decision comes down to whether the doubling of the L3 cache will provide a noticeable improvement. There are many benchmarks, and a lot of discussion, regarding CPU power. However, I find very little discussion of L3 cache utilization, and how increases in the L3 cache (such as doubling it with dual processors) affect performance. For example: If there are only two processes running, but each benefits from a large L3 cache (such as might be the case for background processes that frequently scan the file system), perhaps the overall system performance might noticeably improve with dual CPU's - even if only a single core is active on each CPU - due to each process having double the effective L3 cache. I am hoping that someone has a sense of the benefits of increasing (or doubling) the L3 cache size. Note: the CPU I am considering (the Xeon E5-2687W) has 20 MB L3 cache, so a system with dual CPU's would have 40 MB L3 cache.

• DPM 2010 PowerShell Script to Easily Restore Multiple Files

  - by bmccleary

  I’ve got what I thought would be a simple task with Data Protection Manager 2010 that is turning out to be quite frustrating. I have a file server on one server and it is the only server in a protection group. This file server is the repository for a document management application which stores the files according to the data within a SQL database. Sometimes users inadvertently delete files from within our application and we need to restore them. We have all the information needed to restore the files to include the file name, the folder that the file was stored in and the exact date that the file was deleted. It is easy for me to restore the file from within the DPM console since we have a recovery point created every day, I simply go to the day before the delete, browse to the proper folder and restore the file. The problem is that using the DPM console, the cumbersome wizard requires about 20 mouse clicks to restore a single file and it takes 2-4 minutes to get through all the windows. This becomes very irritating when a client needs 100’s of files restored… it takes all day of redundant mouse clicks to restore the files. Therefore, I want to use a PowerShell script (and I’m a novice at PowerShell) to automate this process. I want to be able to create a script that I pass in a file name, a folder, a recovery point date (and a protection group/server name if needed) and simply have the file restored back to its original location with some sort of success/failure notification. I thought it was a simple basic task of a backup solution, but I am having a heck of a time finding the right code. I have seen the sample code at http://social.technet.microsoft.com/wiki/contents/articles/how-to-use-a-windows-powershell-script-to-recover-an-item-in-data-protection-manager.aspx that I have tried to follow, but it doesn’t accomplish what I really want to do (it’s too simplistic) and there are errors in the sample code. Therefore, I would like to get some help writing a script to restore these files. An example of the known values to restore the data are: DPM Server: BACKUP01 Protection Group: Document Repository Data Protected Server: FILER01 File Path: R:\DocumentRepository\ToBackup\ClientName\Repository\2010\07\24\filename.pdf Date Deleted: 8/2/2010 (last recovery point = 8/1/2010) Bonus Points: If you can help me not only create this script, but also show me how to automate by providing a text file with the above information that the PowerShell script loops through, or even better, is able to query our SQL server for the needed data, then I would be more than willing to pay for this development.

• Monitoring tools that can take high rate and high volume?

  We're using Cacti with RRDTool to monitor and graph about 100,000 counters spread across about 1,000 Linux-based nodes. However, our current setup generally only gives us 5-minute graphs (with some data being minute-based); we often make changes where seeing feedback in "near real time" would be of value. I'd like approximately a week of 5- or 10-second data, a year of 1-minute data, and 5 years of 10-minute data. I have SSD disks and a dual-hexa-core server to spare. I tried setting up a Graphite/carbon/whisper server, and had about 15 nodes pipe to it, but it only has "average" for the retention function when promoting to older buckets. This is almost useless -- I'd like min, max, average, standard deviation, and perhaps "total sum" and "number of samples" or perhaps "95th percentile" available. The developer claims there's a new back-end "in beta" that allows you to write your own function, but this appears to still only do 1:1 retention (when saving older data, you really want the statistics calculated into many streams from a single input. Also, "in beta" seems a little risky for this installation. If I'm wrong about this assumption, I'd be happy to be shown my error! I've heard Zabbix recommended, but it puts data into MySQL or some other SQL database. 100,000 counters on a 5 second interval means 20,000 tps, and while I have an SSD, I don't have an 8-way RAID-6 with battery backup cache, which I think I'd need for that to work out :-) Again, if that's actually something that's not a problem, I'd be happy to be shown the error of my ways. Also, can Zabbix do the single data stream - promote with statistics thing? Finally, Munin claims to have a new 2.0 coming out "in beta" right now, and it boasts custom retention plans. However, again, it's that "in beta" part -- has anyone used that for real, and at scale? How did it perform, if so? I'm almost thinking about using a graphing front-end (such as Graphite) and rolling my own retention backend with a simple layer on top of mmap() and some stats. That wouldn't be particularly hard, and would probably perform very well, letting the kernel figure out the balance between frequency of flushing to disk and process operations. Any other suggestions I should look into? Note: it has to have shown itself able to sustain the kinds of data loads I'm suggesting above; if you can point at the specific implementation you're referencing, so much the better!

• Mysql innoDB corruption after server crash

  - by Ward Loockx

  Yesterday my server died because an outage in the data center. Today it's back up, but having some problems with mysql. First of all my mysql server was not able to start. For this reason I deleted the files ib_logfile0 and ib_logfile1 in /var/lib/mysql folder (I still have the old failing files). After this my server was able to startup again. But now I see a lot of issues in the mysql log file. Sep 1 09:43:55 * mysqld: 120901 9:43:55 InnoDB: Error: page 70944 log sequence number 8 1483471899 Sep 1 09:43:55 * mysqld: InnoDB: is in the future! Current system log sequence number 5 612394935. Sep 1 09:43:55 * mysqld: InnoDB: Your database may be corrupt or you may have copied the InnoDB Sep 1 09:43:55 * mysqld: InnoDB: tablespace but not the InnoDB log files. See Sep 1 09:43:55 * mysqld: InnoDB: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html When I check the docs on mysql.com, I found that I need to recover my database with backups. I have a backup but not sure what's the good way on importing it. Or is there a way to recover without having to re-import the database again? So if I'm correct I need to put innodb_force_recovery to 4 in mysql and delete all current data and re-import? Is there a way to do this without having downtime? I also have one slave running. This slave has the current status now: Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. How can I totally reset the slave after the new import on the master has happend? Hopefully we can find a solution without not to much downtime. Thanks!

• My network drive disappears from Mac OS Finder

  - by Mariusz

  I have recently bought a Netgear WNDR3800 router to use it in my home network. But just the same day I installed it, I noticed a strange behaviour of Finder and iTunes. Let me explain it further. There is a Synology DS111 NAS attached to that router and two Macs with Mac OS X Lion. One of them is connected by a cable and the second one wirelessly. Before I changed my router to the new one I mentioned above, Finder always used to display my NAS on its sidebar. So I could just click its network name to access shared folders existing on it. But after I installed WNDR3800, I can no longer access the NAS that way. It is no longer displayed. I always have to mount it manually by typing its IP address using the Finder's 'connect to server' option. The same NAS supports TimeMachine backups and has an inbuilt DLNA server. And the same situation here. I can't perform a backup because my NAS is no longer accessible in TimeMachine preferences. iTunes does not display it as well (as a multimedia server) even though it used to before I installed that router. What's important, everything works fine for a couple of minutes after I restart the router or the NAS. Or even when I change the NAS's IP address it becomes accessible again in Finder, TimeMachine and iTunes, but only for some time. Both the Mac computers I mentioned behave the same way. And all those issues have been taking place sice I installed that new router. Before I did that, everything had worked fine. My old router was Netgear WGR614v10. Would you be so kind to tell me what you think could possibly be the reason of that behaviour? What settings of the router should I look closer at? I'm not a network specialist, but is it possible that some network packets are blocked for some reason? I will be grateful for any clues you give me. Thank you.

• Multiple OS's and GRUB chainloading

  - by Kent

  Hi, I want to have multiple OS installations and I have been advised that chain loading using GRUB is a good way to handle this. I have looked at tutorials on the web but I still have some questions before I can start. I want: Windows XP: 20 GB. For running some school stuff and a game which does not work through WINE. Xubuntu 9.04: 85 GB. My main OS. Another Linux distribution: 15 GB . For experimenting and trying Linux distributions out. I will: Wipe and install various distributions quite often on the 15 Use dd to make a copy of my Windows partition after installing it and getting things to work as I like. My experience is that Windows needs to be re-installed maybe once per year to not get bloated and slow. I have been told: To use GRUB chain loading. It will make it easier when kernel upgrades are made in the Linux distributions, as they modify the GRUB boot-menu. To my understanding I need to: (I might very well be mistaken) Install Windows first. Then install Xubuntu and let it write over the MBR with GRUB (I guess this is the default). Get the GRUB on the MBR start Windows XP if I want to (it's done by default), start Xubuntu using the kernel of my choice or defer execution to the boot sector of my other Linux distribution. The actual chain loading will only occur when I want to start my experimental install of Linux. I wonder: Is step 3 above correct and a good way to handle this? Is it also a good way to use chain-loading for both Xubuntu and my experimental Linux installation? How do I get a Linux distribution to install the boot loader it comes with to the boot sector of its partition and not to the MBR? If I can't get it to not touch the MBR. Then I could make a backup of the MBR using dd and then write it back after installing my experimental Linux installation. But then, how would I get the boot loader (lets say GRUB) into the boot sector of the experimental Linux installation? How would it work if said Linux installation gets a new kernel update and needs to update the GRUB menu?
