• Backup strategy for developer-focused Apple environments?

  - by ewwhite

  It's interesting to see the technological split between structured corporate environments and more developer-driven/startup environments. Some of the Microsoft technologies I take for granted (VSS, Folder Redirection, etc.) simply are not available when managing the increasing number of Apple laptops I see in DevOps shops. I'm interested in centralized and automated backup strategies for a group of 30-40 Apple laptops... How is this typically done safely and securely, assuming these are company-owned machines (versus BYOD)? While Apple has Time Machine, it's geared toward individual computer backups and doesn't seem to work reliably in a group setting. Another issue with these workstations is the presence of Vagrant/Virtual Box VMs on the developers' systems. Time Machine and virtual machines typically don't work well unless the VMs are excluded from the backup set. I'd like a push-based backup process with some flexible scheduling options. I know how to handle the backend storage, but I'm not sure on what needs to be presented to the client systems. Due to the nature of the data here, cloud-based backup may not be a viable option. Any suggestions about how you handle this in your environment would be appreciated. Edit: The virtual machine backups are no longer important. They can be excluded from the process and planning.

• Recovering Data from a Linkstation LS-WXL/R1

  - by kingkool68

  I've been running a Buffalo Linkstation LS-WXL/R1 in RAID1 for a few weeks. Two nights ago we had a brief power outage. Yesterday when I tried to mount the disk it couldn't be found. I logged in to the web admin and it couldn't see any storage attached and no arrays available. Well this sucks. I ended up taking the disks out and mounting them to an Ubuntu virtual machine. They how up as an Array but I can't start the Array to the best of my limited knowledge. I could still see the 6 partitions, so I'm confident the data is there. I can use Photorec (http://www.cgsecurity.org/wiki/PhotoRec) to recover most of the files I want, it just takes some time. Could I make an image of the data partition and mount that in Ubuntu so I can get at the data I want through the file system? 95% of the data on my Linkstation LS-WXL/R1 is backup. I just put a few folders of images on there that I need to get back. I'm already preparing to format the disks when I'm done and re-building the RAID1 array from scratch. Any advice would be appreciated.

• I need an admin toolset for Windows 2003 and 2008

  - by eugeneK

  i know this is way too general question but anyway. I need few tools, will write down my tasks as sysadmin and if you have any to automate my job i would be glad to hear. I don't mind paying for software needed unless it is way too expensive. First of i backup all files on server at local/office storage. I 7zip all SQL backup files and then move them over network to centralized location and then FTP them from office PC which has no FTP server installed and cannot have one. Backups happen at 4AM at the morning thus i need to set time for compressing and afterward FTPing. Then i FTP all IIS web application as differentiation backup, same goes for VOD movies. Second tool i need is system monitor which will monitor all servers from themselves and from external location for CPU/Memory/Hard disk and other basic failures. This tool should able to execute Website address with parameters which will send me an email with all report on failure. Third tool i need is a way to get all Event Logs from 10 Windows based servers without accessing each any of them manually. If you know any solution, thanks in advance.

• Symbolic links not working in MySQL

  - by Eno

  I'm having an issue, I searched a lot but I'm not sure if it's related to a previous security patch. On the last version of MySQL on Debian Lenny ( 5.0.51a-24 ) I need to share one table between two db, those two db are in the same path ( /var/lib/mysql/db1 & db2 ). I created symbolic links for db2 pointing to the table in db1. When I query the same table from db2 I get this : 'ERROR 1030 (HY000): Got error 140 from storage engine' This is how it looks : test-lan:/var/lib/mysql/test3# ls -alh drwx------ 2 mysql mysql 4.0K 2010-08-30 13:28 . drwxr-xr-x 6 mysql mysql 4.0K 2010-08-30 13:29 .. lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.frm -> /var/lib/mysql/test/blbl.frm lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYD -> /var/lib/mysql/test/blbl.MYD lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYI -> /var/lib/mysql/test/blbl.MYI -rw-rw---- 1 mysql mysql 65 2010-08-30 13:24 db.opt I really need those symlinks, is there a way to make them working like before ? ( old MySQL-server is fine ) Thanks,

• Server Admin is not allowing me to configure DNS

  - by Clinton Blackmore

  We have a Mac OS X 10.5.8 Server running DNS (and a few other services). When I connect to it (using Server Admin 10.5.3 [which comes from the Server Admin 10.5.7 tools]), and click to look at the DNS settings, all appears normal -- it shows many reverse entries and two top-level domains. However, when I select one of our domains and open the disclosure triangle, the list is empty! [There should be over a dozen entries, and the reverse entries do show up.] If I then tell it I want to add, say, an A Record to the domain, almost everything disappears -- and I am left with a list showing our two domains, one with a disclosure triangle underneath it showing a single entry, and one reverse entry to correspond to the new A record. named appears to be working fine. DNS names resolve. It appears to simply be that Server Admin is having problems with the data on the computer. No one here would have manually created a DNS entry. Now, while I think I've backed up the DNS (I backed up /var/named/, /etc/named.conf, and /etc/dns/, as mentioned here), I'm really not sure if just replacing the files would restore the DNS settings we have if things go south. I am contemplating going to settings and changing the log level from "Information" to "Debug", but 1) I am just a little concerned that it might write a bad configuration to the disk, and 2) I think it would only affect named and not Server Admin, and, so far as I can tell, named is not having a problem. (Nothing looks strange in /Library/Logs/named.log when I open it via Console/Terminal. Oddly, though, when I click on the 'log' button for DNS in Server Admin, I see no text at all, just a fully white window. When I look at one of our secondary DNS servers, I am able to see the log file through Server Admin.) This entry appears in the system log when I run Server Admin on the server: Jun 17 09:02:08 od1 Server Admin[3892]: Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription It seems to occur after I've looked at DNS, look at another service, and then click back on DNS. Think that the most likely cause is a corrupt configuration file, I glanced through all the files that I backed up, and none of them is obviously gobbledygook. Here are some oddities I find when running Server Admin from a remote computer to manage the DNS. When I click to see the log file for DNS, the server starts writing messages like these to its system.log: Jun 17 09:59:04 od1 kernel[0]: Limiting open port RST response from 252 to 250 packets per second Jun 17 09:59:06 od1 kernel[0]: Limiting open port RST response from 258 to 250 packets per second This stops when I click on a different service. The inderterminate progress indicator (the spinning wheel that appears beside the "Revert" and "Save" buttons in the bottom-right corner of Server Admin) looks really strange. As far as I can tell, instead of just spinning and waiting, it is being told to start spinning repeatedly, resulting in a jerky animation. Here are some of the messages being logged on the computer running Server Admin: At startup: *** ERROR: -[GRAxes computeLayout]:1124 - plotRect height = 0.000000 <= 0.0 *** *** ERROR: -[GRChartView computeLayout]:1194 - Layout for overlay axes (0x18758f50) failed. *** (These messages don't concern me too much as they go away for a while if you delete ~/Library/Preferences/com.apple.ServerAdmin.plist). At shutdown: 2010-06-17 10:02:17.202 Server Admin[7770:10b] *** -[GroupTextField windowDidResignKey:]: unrecognized selector sent to instance 0x16e12490 More concerning are these messages: 2010-06-17 09:59:47.269 Server Admin[7770:10b] Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription Server Admin(7770,0xb0453000) malloc: *** error for object 0x1c115390: double free *** set a breakpoint in malloc_error_break to debug 2010-06-17 10:01:00.795 Server Admin[7770:10b] *** -[ServiceEntry sessionHost]: unrecognized selector sent to instance 0x2af500 Any thoughts on: what the problem is how I can troubleshoot it or how to fix it? If I do need to wipe out DNS and restart, is there a good way to do this?

• How much memory will a Windows file-server be able to use effectively.

  - by Zoredache

  In the near future we will be moving our fileserver to a newer box that will be running Windows 2008R2. I want to know how much memory Windows will be able to use for a system that is just a file-server. In searching around I found an old document for Windows 2000 that mentions the maximum size of the file-system cache is 960MB. I suspect this limit no longer applies, but is there a new limit? The file server will be just a standard Windows fileserver. It will have 1TB of attached storage. The large majority of the of the files accessed during the day are just typical Office documents. There are 80-100 people usually using the fileserver during a typical day. This system will only be used as a file server, it doesn't have any other roles. In Windows 2008r2 is there any hard limits for the filesystem cache? What are they? The server we will be re-using for this purpose currently has 4GB of memory, but it can be maxed out at 16GB. Is there any value in doing this for a Windows file-server? Are there any performance counters can I look at on the existing 2003 fileserver that will tell me if adding more memory will be worthwhile.

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• simple and reliable centralized logging inside Amazon VPC

  - by Nakedible

  I need to set up centralized logging for a set of servers (10-20) in an Amazon VPC. The logging should be as to not lose any log messages in case any single server goes offline - or in the case that an entire availability zone goes offline. It should also tolerate packet loss and other normal network conditions without losing or duplicating messages. It should store the messages durably, at the minimum on two different EBS volumes in two availability zones, but S3 is a good place as well. It should also be realtime so that the messages arrive within seconds of their generation to two different availability zones. I also need to sync logfiles not generated via syslog, so a syslog-only centralized logging solution would not fulfill all the needs, although I guess that limitation could be worked around. I have already reviewed a few solutions, and I will list them here: Flume to Flume to S3: I could set up two logservers as Flume hosts which would store log messages either locally or in S3, and configure all the servers with Flume to send all messages to both servers, using the end-to-end reliability options. That way the loss of a single server shouldn't cause lost messages and all messages would arrive in two availability zones in realtime. However, there would need to be some way to join the logs of the two servers, deduplicating all the messages delivered to both. This could be done by adding a unique id on the sending side to each message and then write some manual deduplication runs on the logfiles. I haven't found an easy solution to the duplication problem. Logstash to Logstash to ElasticSearch: I could install Logstash on the servers and have them deliver to a central server via AMQP, with the durability options turned on. However, for this to work I would need to use some of the clustering capable AMQP implementations, or fan out the deliver just as in the Flume case. AMQP seems to be a yet another moving part with several implementations and no real guidance on what works best this sort of setup. And I'm not entirely convinced that I could get actual end-to-end durability from logstash to elasticsearch, assuming crashing servers in between. The fan-out solutions run in to the deduplication problem again. The best solution that would seem to handle all the cases, would be Beetle, which seems to provide high availability and deduplication via a redis store. However, I haven't seen any guidance on how to set this up with Logstash and Redis is one more moving part again for something that shouldn't be terribly difficult. Logstash to ElasticSearch: I could run Logstash on all the servers, have all the filtering and processing rules in the servers themselves and just have them log directly to a removet ElasticSearch server. I think this should bring me reliable logging and I can use the ElasticSearch clustering features to share the database transparently. However, I am not sure if the setup actually survives Logstash restarts and intermittent network problems without duplicating messages in a failover case or similar. But this approach sounds pretty promising. rsync: I could just rsync all the relevant log files to two different servers. The reliability aspect should be perfect here, as the files should be identical to the source files after a sync is done. However, doing an rsync several times per second doesn't sound fun. Also, I need the logs to be untamperable after they have been sent, so the rsyncs would need to be in append-only mode. And log rotations mess things up unless I'm careful. rsyslog with RELP: I could set up rsyslog to send messages to two remote hosts via RELP and have a local queue to store the messages. There is the deduplication problem again, and RELP itself might also duplicate some messages. However, this would only handle the things that log via syslog. None of these solutions seem terribly good, and they have many unknowns still, so I am asking for more information here from people who have set up centralized reliable logging as to what are the best tools to achieve that goal.

• How to use Zune software to listen to podcasts with generic MP3 player?

  - by Bevan

  I listen to a bunch of podcasts - a great way to fill the otherwise mindless space of a daily commute. My MP3 player is a Transonic brand, appears on my computer as a generic storage device. I've been using iTunes to download the podcasts, and manually moving the files out of the disk folder onto my player, but this is pretty tedious. iTunes also fails to recognise that the files are gone and leaves them in the list. (Actually, iTunes for windows is pretty much a dog, but that's a different rant.) The Zune software is 99% of what I want in a podcast downloader - performs well, looks nice, downloads reliably and so on. Some features - like only downloading the next five unheard episodes of a podcast - are superb. However, if I manually move the files across to the MP3 player, the Zune software concludes that the file has never been downloaded, and downloads it again. This leads me to my question: What is a good way to use the Zune software to download podcasts for listening on a generic MP3 player? Are there any addons for the Zune software to make this easier? Registry hacks? Can I configure the Zune software to not download the same episode multiple times? Is there a way for the Zune software to populate my MP3 player directly, instead of having to copy files?

• Regular issue with keys on temp tables

  - by Christian

  We run a large forum with lots of reads and writes, particularly to the posts and topics tables which are both innodb. Last week I started doing 12 hourly backups with innobackupex because mysqldump just takes forever (7+ million rows in posts table.) It seems that something doesn't like these backups because I have a recurring problem every other day. The symptoms; The front page of the site starts throwing errors The logs start showing errors like Error: 126 - Incorrect key file for table '/tmp/mysql/#sql_4e87_14.MYI'; try to repair it The /tmp/ dir fills up and we start getting Error: 1030 - Got error 28 from storage engine in the logs. The only way to fix is to optimize table on each of the posts and topics tables. I'm trying all I can to stop MySQL using disks for temp tables, but I'd have more problems than this if it used all my memory also. My my.cnf is here; https://gist.github.com/cbiggins/0aa26f6defb7a14541d7 The box has 32GB memory and I don't come near that usually. Currently at 15GB use. Thanks in advance. Update 1: Despite the conf looking like there is replication, there isn't. This is a stand alone instance.

• PostgreSQL 8.4 - Tablespace Optimization

  - by FloE

  I'm currently running a PostgreSQL Database with about 1.5 billion rows / 500 GB of data (including indices). There are several schemata: on for the (read only, irregular changes / updates) 'core-model' and one for every user (about 20 persons). The users can access the core and store data in their own schema, so everything is located in one database. The server runs with CentOS and PostgreSQL 8.4 and is used for scientific studies, exploration etc and is running quite well. These days an upgrade of the DB storage hard disks arrive - all with the same performance as the old ones. I'm looking for the best way to distribute the data on these disks. It would be possible to separate frequently used objects (the core-data) from the user schemata, but I'm not sure if this is really worth the effort. It seems to be a much better idea to move the WAL files (pg_xlog directory) to its own partition. http://www.postgresql.org/docs/8.4/static/wal-internals.html What are your opinions? Are there any tablespace- or partitioning-related performance documentations / benchmarks?

• Home server hard drive: 186k start-stop cycles in 325 days?

  - by j-g-faustus

  I set up a home server about a year ago, using Ubuntu server (10.04 LTS at the moment), four disks in RAID 5 for storage (WD Green 1.5 TB) and a laptop drive for the OS. Today the output of smartctl, a command line utility for checking the SMART attributes of a hard drive, tells me that the primary OS drive has had no less than 186,000 start-stop cycles in 325 days and may be nearing the end of its lifespan. The smartctl output is in "normalized values", in this case a number between 200 and 000, where 200 is "brand new" and 000 means "worn out". My disk gets 001. So I wonder what happened: 186k start/stop cycles in 7820 hours is about one start/stop per 2.5 minutes around the clock. This seems somewhat excessive for a computer that sees actual use once or twice per day. (The RAID disks are normal, averaging to one start/stop per day, as expected.) Does anyone have similar experiences, or pointers to what might be the issue here? Specifically I'd like to know Why the massive start/stop count? Do I have some sort of configuration issue? Could there be a background service that is causing trouble? Could having a laptop disk as the OS drive be part of the problem? Can anyone confirm or deny this? Here is the /etc/hdparm.conf configuration /dev/sda { apm = 127 spindown_time = 120 } and the most relevant parts of smartctl --attributes /dev/sda: smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 001 001 000 Old_age Always - 185875 9 Power_On_Hours 0x0032 090 090 000 Old_age Always - 7820 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 109 193 Load_Cycle_Count 0x0032 118 118 000 Old_age Always - 246833 194 Temperature_Celsius 0x0022 107 098 000 Old_age Always - 36 As I generally prefer my drives to last more than a year, any advice is appreciated.

• Windows Home Server installation fails because it can't find the DVD drive anymore

  - by BBlake

  I've got an old Dell Dimension 8300 desktop I decided to convert into a WHS box. I popped in a pair of 1 TB SATA drives, which were recognized fine by the BIOS and the currently installed OS (XP), so I decided to go ahead and install WHS. Near the end of the installation, WHS acts like it can no longer find the DVD drives (either of them, the box has a DVDROM and a DVDRW). The specific error is gives is the "Can't configure storage" error. I've found several forums where people say they get this error if they remove the boot DVD during the installation (at the time of the first reboot). However, I never removed the DVD. After the error, if fails into WHS, so it did mostly install and I can work with WHS. However, it refuses to recognize the network card, video card and while it shows the two DVD drives, any CD/DVD I insert in either drive the system says is corrupted and unreadable, even though none of them are. I've tried several reinstalls both removing and not removing the DVD, but the result is the same regardless. Any other tricks anyone found? If I can't figure this out, maybe I'll just install SBS2008 and fake it up to be similar to WHS with some addin tools. Shouldn't be too hard to create something since WHS is based on SBS2003 anyway.

• Need Suggestions on Backup Strategies and Alternatives?

  - by Leejo

  I'm not sure where else to post this question since it is not exactly Code or Development related...but I know Stackoverflow is a very responsive to questions... Currently, I use Mozy Home to perform an online backup of my laptop. So far, this works well, since I only use one laptop that needs to be backed up. But, soon this may change and I want to explore other alternatives than having to perform an online backup on all machines. Ideally, I want to set up a Network Computer (Laptop/Desktop) with enough storage to hold the backups for all other machines that I would have. Each machine should be responsible for performing their backup (to the Network Computer). This would require some capability like Mozy's incremental backup strategy, but instead of online backup, I would prefer it to be done locally to the Network Computer. Can you recommend a local backup software (backup to a network pc, incremental backup, good restore options)? I'm also looking for any ideas on a local backup strategy even if its different from what I've stated? What works and what doesn't work? Thanks in advance for your help!

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger. After reboot it said that config file is missing or corrupted. So, I boot to recovery console and found that registry file (config) is so small. I've replaced it with one from recovery point and windows booted sucessfully. But after about 3 hrs -- it has crashed again in the same wat! I look in event viewer: is said that Explorer.exe failed to open \global??\DLIAFS. I look in winobj, and found that it is a device. I made "deny from everyone" for this device ACL, and after several hours my windows crashed. I restored registry, boot again and there was no error about DLIAFS. I did full chkdsk and it did not found anything bad. But I found event about error paging to \Harddrive1\D. I do not have pagefile there, but I thought I should check my disk again. Unfortunatelly I cannt use smart tools for RAID, but I downloaded latest software from Intel (it can do the same things like RAID bios can but from windows). It verified my disks, found some errors, fix them, than I rebooted. And it crashed again. I am lost. What (except kernel debugging) could be done here? Thanks

• How to backup a NAS drive to a USB drive?

  - by Tim Murphy

  How would you backup 600+ GB of data on a NAS (Network-Attached Storage) drive to a USB external drive? The NAS drive does not contain mission critical data nonetheless I wish to make weekly copies of it just in case. The NAS drive is almost exclusively used as an archive dump and is rarely updated. However the backup strategy used must have a simple restore procedure so I can confidently say the data now on the NAS drive is exactly how it was at the time of backup. I did try xcopy but seemed like it would take many-many hours and eventually crashed with insufficient memory. http://www.ctunion.com/node/114 suggests I would need to use xxcopy instead due to folder/file name lengths. My concern with xcopy/xxcopy is the length of time it takes. Hoping something else is faster. NAS drive is DLink DNS-313. 1TB drive installed. Connected to router via Ethernet cable. USB drive is Seagate 1TB. Can be connected to Windows Vista (preferred) or Windows 7 PCs. Both PCs are usually connected Wirelessly however ethernet cable can be used during backup to speed up the process.

• Abysmal transfer speeds on gigabit network

  I am having trouble getting my Gigabit network to work properly between my desktop computer and my Windows Home Server. When copying files to my server (connected through my switch), I am seeing file transfer speeds of below 10MB/s, sometimes even below 1MB/s.

The switch lights up with green lights for those two ports, indicating 1Gbps. When connecting the machines through the switch, I am seeing insanely low speeds from WHS to the desktop measured with iperf: 10Kbits/sec (WHS is running iperf -c, desktop is iperf -s). Using iperf the other way (WHS is iperf -s, desktop iperf -c) speeds are also bad (~20Mbits/sec). Connecting the machines directly with a patch cable, I see much higher speeds when connecting from desktop to WHS (~300 Mbits/sec), but still around 10Kbits/sec when connecting from WHS to the desktop. File transfer speeds are also much quicker (both directions).

• Ubuntu Device-mapper seems to be invincible!

  - by Andrew Bolster

  I'm working on a hopefully unrelated question question and I've got to a strange situation. First: I know very little about the very low level hardware kernal storage driver magix, so I'm hoping a) someone can help and b) someone can explain it to me better. I've been trying a dozen different configurations of my 2x500GB SATA drives over the past few hours involving switching between ACHI/IDE/RAID in my bios; After each attempt I've reset the bios option, booted into a live CD, deleting partitions and rewriting partition tables left on the drives. Now, however, I've been sitting with a /dev/mapper/nvidia_XXXXXXX1 that seems to be impossible to kill! its the only 'partition' that i see in the Ubuntu install (but I can see the others in parted) but it is only the size of one of the drives, and I know I did not set any RAID levels other than RAID0. Anyone have any ideas how I can kill this and get back to just two independent IDE drives? Or can anyone convince me of a reason to go the AHCI route? Many thanks in advance.

• multi-user rvm gem install failure when called from CloudFormation::Init

  - by Peter Mounce

  I've taken an Amazon Linux AMI (based on CentOS) and installed RVM (1.10.3) to it in multi-user fashion (see {1} below). I used that to install ruby 1.9.3-p125, rubygems 1.8.17, and bundler 1.1 as the baseline requirements for most things I'm going to be using the instances for. I've captured that instance to an AMI, and am now launching it via CloudFormation, with some CloudFormation::Init commands. One of them is to use s3cmd to pull down a private gem from S3, and the next one, the one that fails, is to install that gem. It fails with an error message 2012-03-15 16:53:20,201 [ERROR] Command 20_install_gems (/usr/local/rvm/rubies/ruby-1.9.3-p125/bin/gem install ./*.gem) failed 2012-03-15 16:53:20,202 [DEBUG] Command 20_install_gems output: /usr/local/rvm/rubies/ruby-1.9.3-p125/bin/gem:12:in `require': no such file to load -- rubygems (LoadError) from /usr/local/rvm/rubies/ruby-1.9.3-p125/bin/gem:12 Now, that happens during the cfn-init execution - I assume, but haven't checked yet, that cfn-init is being run with an environment different from that of ec2-user (there are no other users on the instance). If I run gem install mygem.gem in an interactive session then that works fine. So, my question really, is what should I do to make this work for cfn-init? Have I correctly set up rvm as multi-user? I've confirmed that cfn-init is being run as the root user, with his restricted environment. How should I source the /etc/profile.d/rvm.sh into root's sessions? {1} My semi-automated rvm installation steps (run in interactive session as ec2-user): sudo bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer ) sudo gpasswd -a ec2-user rvm # iconv-devel is baked into centos' glibc sudo yum install -y autoconf automake bison bzip2 gcc-c++ git libffi-devel libtool libxml2-devel libxslt-devel libyaml-devel make openssl-devel patch readline readline-devel zlib zlib-devel source /etc/profile.d/rvm.sh rvm list known # in a new session: rvm install ruby-1.9.3-p125 rvm use 1.9.3 --default gem update --system # gems required by public_web-awareness gem install aws-sdk bundler cocaine sinatra echo -e "gem: --no-ri --no-rdoc\n" > /home/ec2-user/.gemrc # delete unnecessary documentation files rm -rf `gem env gemdir`/doc sudo -s sudo echo -e "gem: --no-ri --no-rdoc\n" > /etc/skel/.gemrc sudo echo -e "gem: --no-ri --no-rdoc\n" > /etc/gemrc # ctrl + d out of the sudo session Some environment information: [ec2-user@ip ~]$ echo $PATH /usr/local/rvm/gems/ruby-1.9.3-p125/bin:/usr/local/rvm/gems/ruby-1.9.3-p125@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p125/bin:/usr/local/rvm/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/bin [ec2-user@ip ~]$ echo $GEM_HOME /usr/local/rvm/gems/ruby-1.9.3-p125 [ec2-user@ip ~]$ echo $GEM_PATH /usr/local/rvm/gems/ruby-1.9.3-p125:/usr/local/rvm/gems/ruby-1.9.3-p125@global [ec2-user@ip ~]$ echo $BUNDLE_PATH [ec2-user@ip ~]$ gem list *** LOCAL GEMS *** aws-sdk (1.3.6) bundler (1.1.0) cocaine (0.2.1) httparty (0.8.1) json (1.6.5) multi_json (1.1.0) multi_xml (0.4.1) nokogiri (1.5.1, 1.5.0) rack (1.4.1) rack-protection (1.2.0) rake (0.9.2) sinatra (1.3.2) tilt (1.3.3) uuidtools (2.1.2) yamler (0.1.0)

• Why is Automator crashing on launch?

  - by zbrimhall

  I've run into an odd problem where Automtor.app on Snow Leopard crashes on launch. At some point in the past, I put a copy of iPhoto.app into my public directory to copy over to another machine. Now, Automator.app won't run unless my public directory has a copy of iPhoto.app in it. If I remove it, Automator.app crashes on launch. Here's what happens: Launch Automator.app After the Automator menu bar appears, but before any windows appear, I get the dreaded beach ball for a few seconds Automator crashes Here's the output from Console.app: 12/26/09 2:11:24 PM Automator[11736] The action “Add Movie to iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Get iDVD Slideshow Images” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Initiate Remote Broadcast” could not be loaded because the application “QuickTime Broadcaster” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Movie Sequence” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Slideshow” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New QuickTime Slideshow” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set iDVD Background Image” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set iDVD Button Face” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie Annotations” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie Playback Properties” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie URL” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Show Main iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path The value %@ is invalid.: The file “The value %@ is invalid.” couldn’t be opened because there is no such file. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path /Users/brimhall/Public/iPhoto.app: The file “iPhoto.app” couldn’t be opened because there is no such file. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path The value %@ is invalid.: The file “The value %@ is invalid.” couldn’t be opened because there is no such file. 12/26/09 2:11:26 PM Automator[11736] -[NSAttributeDictionary length]: unrecognized selector sent to instance 0x49c770 12/26/09 2:11:26 PM Automator[11736] -[NSAttributeDictionary length]: unrecognized selector sent to instance 0x49c770 12/26/09 2:11:38 PM com.apple.launchd.peruser.501[203] ([0x0-0x2ad2ad].com.apple.Automator[11736]) Job appears to have crashed: Segmentation fault I've tried deleting my Automator.app Preferences file and Application Support directory to get it to look for iPhoto.app in the system-wide Applications directory, but to no avail.

• What's the lowest cost, legal, Microsoft server stack you can assemble?

  - by McKAMEY

  Assuming that you have an app infrastructure that generally only requires: ASP.NET MVC / C# / .NET Database or NoSQL data store (must be accessible from C#) Here's the challenge to you server gods: What is the least expensive configuration that will allow you to deploy to production in a way that doesn't break any licensing rules? In what ways does this solution differ from the "standard" Microsoft deployment scenario? Where does this solution's performance break down once the app begins to scale? I'm not concerned about the hardware, only the server software itself. I would love to hear about any solutions you've personally put into production. Especially if they are unique alternatives. For ideas, consider some of the possible variations, a) any Microsoft server solutions where they have lowered the barrier to entry to compete with OSS, or b) any OSS alternatives to Microsoft products which perform at a similar level. An example of a): SQL Server 2008 Express Edition SP1 is a 100% free version of SQL Server which will scale to the needs of many smaller / early stage applications. An example of b): running the Mono Framework on Linux. An example of differing from the "standard" stack: running Mono on Linux will require a completely different server OS familiarity. None of the Windows-based knowledge really transfers. An example of breaking down under scale: SQL Server Express will only scale to 1GB of memory and 4GB of disk storage. After that point, the application will need to move to one of the paid versions of SQL Server.

• USB drive dead after stopping copying process on Snow Leopard Server

  - by Anriëtte Combrink

  Hi there I was copying to a flash drive from our Snow Leopard server when I stopped the copying process half way through. The device then disappeared from the Desktop. So I unplugged it and plugged it right back in. The device just didn't show up. I unplugged it and plugged it into a Windows XP machine as well as a Windows 7 machine. On both machines, I right clicked "My Computer" and selected "Manage…". On both PC's, the device was located under Removable Storage, but had no size and no drive letter. It shows up in "My Computer", but when I choose "Format…" from the right-click menu (context menu), it says the drive could not be formatted. Can someone please advise me? The flash drives is about 5 mins old and should have no reason to be dead. I really can't loose this drive (I don't need the data on it, I just need it to work again), any help would be appreciated. Thanks in advance.

• Somewhat powerful server needed for computationally expensive stuff

  - by Dane Larsen

  So here's my problem. My Dad runs a company that does some rather computationally expensive stuff. This is not supercomputer level stuff, but it does take several hours to run the average job on his Core i7 desktop. He asked me to look into a way to have his customers use the code on an hourly basis, namely via a server. Ideally he'd be able to buy a box for about $1000, and hook it right up to our home connection. Unfortunately, the data that needs to be both sent and received is on the order of several hundred megs. We live in a rural area, and the fastest connection offered is 1.5Mbit/s. Download. It's like .3Mbit/s upload. Not workable. What are the options for this kind of thing? Ideally, we'd have about 2GB of ram, 300-500GB of storage, and a nice dual core, and it has to run some flavor of Linux. Any suggestions? Thanks in advance EDIT: Also, ideally the monthly price would be < $100 per month.

• Exchange MSExchangeIS Mailbox Store Error

  - by Bart Silverstrim

  Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.
