• Bitnami redmine error SVN

  - by Evgeniy

  I'm installing the Bitnami Redmine stack (redmine + subversion). Firstly I install configure and test it locally (Ubuntu 14.04 LTS). And everything is OK. I install Bitnami stack on server (Red Hat 4.4.7-4) and configure SVN. I commit files into SVN and connect project into Redmine with SVN repository, but when I try see it Rredmine displays 404 error. In the Redmine log file I see the following errors: Started GET "/redmine/projects/web-user-panel/repository" for 127.0.0.1 at 2014-04-24 11:34:20 +0300 Processing by RepositoriesController#show as

I googled it, but similar problem fixed should be fixed 3 years ago. I'm installing the latest Bitnami Redmine 2.5.1-1 stack. UPDATE Well, I found next way. If I use the http protocol it works fine, but I should remove access for svn by web. That's why I create virtual host on localhost and get info from svn use 127.0.0.1 IP. <VirtualHost 127.0.0.1:8000> <Location /repo> DAV svn SVNPath "PATH_TO_MY_REPOSITORY" </Location> And this it work good.

• LVM mirror attempt results in "Insufficient free space"

  - by MattK

  Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a solution Not sure if I am making a rookie mistake, or there is something more subtle wrong (I am more familiar with ZFS, new to using LVM): # lvconvert -m1 centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --mirrorlog mirrored --alloc anywhere centos_bi/home /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home /dev/sdi2 /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available The two disks are of the same size, and have identical partition layouts via "sfdisk -d /dev/sdi part_table; sfdisk /dev/sda < part_table".

• Replace dual-XP installs with single-XP install and repartition drive?

  - by caeious

  Hello, The Current Situation I have a hard drive that currently is split up like so: Primary Partition C: 9.77 GB NTFS Healthy (System) with XP Pro (in Polish) installed Extended Partition D: 39.82 GB NTFS Healthy (Boot) with XP Pro (in English) installed 6.30 GB Free space When I start my comuter I get a black and white Windows Boot Manager dual boot screen with 2 choices both being Microsoft Windows XP. The first choice is the English version of XP and the second choice is the Polish version of XP. Images of my Computer Management window and Dual Boot screen The Mission What I need to do is get rid of the entire extended partition (D: 39.82 GB & 6.30 free space) and just have the one primary C: drive which I assume will be somewheres around 55 GB big. So in the end I just want XP Pro in English running on my C: drive and no black and white boot screen to show up when starting up my laptop. The Question How do I go about successfully completing The Mission with out making my computer a useless pile of silicon, plastic and metal? UPDATE: So I went ahead and tried to follow Neal's suggestion but hit a wall. I got to a Windows XP Pro install screen that had the 3 following options as well as my drive data: To set up Windows XP on the selected item, press Enter To create a partition in the unpartitioned space, press C To delete the selected partition, press D 57232 MB Disk 0 at Id 0 on bus 0 on atapi [MBR] C: Partition1 [NTFS] 10001 MB ( 4642 MB free ) Unpartitioned space 6448 MB D: Partition2 [NTFS] 40774 MB ( 26225 MB free ) Unpartitioned space 8 MB I figured I would go with the first choice ((To set up Windows XP on the selected item, press Enter)) because I just wanted to set up Windows XP on C: Partition1 (which was preselected) so I pressed Enter which brought me to a screen displaying this message: You chose to install Windows XP on a partition that contains another operating system. Installing Windows XP on this partition might cause the other operating system to function improperly. CAUTION: Installing multiple operating systems on a single partition is not recommended. So this leads me to 2 new questions: How do I get rid of the Windows XP (Polish language) install on C: Partition 1 so that I can cleanly and safely install Windows XP (English language) on it? Neal, is this what you meant by me possibly having to delete the partition that the Windows XP (Polish language) install was located on? Since I have the option to delete partitions with the 3rd choice ((To delete the selected partition, press D)), should I do that on this screen or wait until I have Windows XP (English language) safely installed on C: Partition 1? I have to ask these questions because I have read that it is possibly dangerous to delete hard drive partitions. Just being cautious.

• External USB drive is failing

  - by dma_k

  I have an external USB 2.0 drive WD My Book Mirror Edition, running in RAID 1 (mirroring) mode. A while ago the hard drive started to fail: it stops responding (directories are not listed returning an error after a big timeout). Sometimes it works for weeks before a failure, sometimes – few hours. Small write operations (like removing few files or editing a small file) do not harm, but when copying large files to the drive over the network, or creating the archive locally, the kernel dumps. Also interesting to note that once kernel has failed, Linux does not want to reboot normally (reboot hangs); when Linux box is shutdown with power button, WD drive does not go to sleep mode (as it usually does): leds continue to run, pressing and holding the "shutdown" button on drive's back panel does not do anything; only unplugging the power cord helps. Here goes the boot log: Aug 16 00:32:21 kernel: [ 1.514106] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver Aug 16 00:32:21 kernel: [ 1.657738] ehci_hcd 0000:00:1d.7: PCI INT A -> GSI 23

I have browsed and read similar error reports here and there and I tried: I have upgraded the kernel from v2.6.26-2 to 2.6.32-5, which has not solved the problem. They say, this might a cable problem. I have tried to replace the USB-to-miniUSB cable (that connects external drive with computer) with another one. No changes. Somebody suggests to try another USB port. I have only 4 external USB ports, tried another one with no success. They say to try uhci_hcd. I have unmounted the device, unloaded ehci_hcd and mounted again. The difference was that now in log I get reset full speed USB device using uhci_hcd and address 2 and similar kernel dumps after a while. They say to echo 128 > /sys/block/sdb/device/max_sectors. I tried it with ehci_hcd with no success (note: I have issued this command after the drive was mounted but before using it actively). I have lauched smartmond and checking periodically the output of smartctl: drive temperature is OK, number of bad sectors and uncorrectable errors is 0. Nothing suspicious is reported by S.M.A.R.T. except maybe the following: Aug 16 12:40:12 kernel: [43715.314566] program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO Aug 16 12:40:13 kernel: [43715.705622] program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO Of course, I have not tried all combinations of above. But unfortunately, I am run out of cardinal ideas. If anybody can advice something specific about the problem, you are very welcome.

• Install MegaCli to Monitor Perc 5/i in Nexentastor 3

  - by Peter Valadez

  I have a Dell 2950 with a Perc 5/i Raid controller that we've already installed Nexentastor 3 Community Edition on. We setup a raid-10 array that and put a ZFS pool on top of the hardware. As I understand, in this configuration ZFS/Nexentastor will not be able to tell when a disk fails in the array. Obviously, this is not optimal. Since the Dell Perc 5/i controller is a rebranded LSI controller, you should be able to use the MegaCli utility to manage the array and monitor its condition. I had seen in a separate forum that the Perc 5/i is very similar to the LSI MegaRAID 8480E, so I tried installing the MegaCli utility at the link below. However, I have not been able to successfully install the utility. http://www.lsi.com/support/products/Pages/MegaRAIDSAS8480E.aspx Here is what happened when I tried to install MegaCli: root@Nexenta2:/files# pkgadd -d MegaCli.pkg Warning: unable to relocate '$BASEDIR' mv: cannot move `solmegacli-8.02.16/' to a subdirectory of itself, `solmegacli-8.02.16//var/lib/dpkg/alien/solmegacli/reloc/solmegacli-8.02.16' mv: cannot move `solmegacli-8.02.16/' to a subdirectory of itself, `solmegacli-8.02.16//opt/solmegacli-8.02.16' 822-date: warning: This program is deprecated.

I've got three questions: Is it possible to install and use MegaCli in Nexentastor 3? If so, how can I install MegaCli on Nexentastor 3? Suggestions welcome!!! If not, is there a better way to monitor the condition of the Perc 5/i hardware raid? Our 2950 does have a DRAC card, so can I use that to monitor the raid condition?

• Xen won't start after it had been working

  - by Paul Tomblin

  I've been setting up this Debian Stable system with a dom0 and 3 domUs. It was working fine for several days, and I'm almost ready to deploy it to the rack.

• iSCSI timeouts under high load

  - by Antonio

  I have two servers connected via Gigabit Ethernet. One is iSCSI target, the second one is initiator. When I run mkfs.ext4 at initiator, after a while disk IO slows down critically. In the target host I can see the following in syslog: Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668c 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668c 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668d 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668d 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668e 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 1196696 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 1196696 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119669e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119669e 6 Sep 14 09:40:04 sh11 tgtd: abort_task_set(1139) found 119669f 0 Sep 14 09:40:04 sh11 tgtd: abort_cmd(1115) found 119669f 6 And load average grows to 12 or even more: # uptime 12:37:00 up 23 days, 13:25, 1 user, load average: 12.00, 7.00, 4.00 CentOS 6.3 tgtd 1.0.24 Intel Pentium 4 2.4GHz 1Gb RAM 2Tb WD Cavlar Green SATA 2.0 #lspci 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 02) 00:01.0 PCI bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE Host-to-AGP Bridge (rev 02) 00:1d.0 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 82) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 02) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV200 QW [Radeon 7500] 02:01.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet Adapter (rev 11) (rev 11) 02:02.0 RAID bus controller: VIA Technologies, Inc.

• Prevent Windows 7 User Accounts from accessing files in other User Accounts

  - by Mantis

  I'm trying to set up another User Account on my Windows 7 Professional laptop for use by another person. I do not want that person to have access to any of the files in my User Account on the same machine. This machine has a single hard disk formatted with NTFS. User accounts data is stored in the default location, C:\Users. I use the computer with a Standard Account (not an Administrator). Let's call my user account "User A." I have given the new user a Standard Account. Let's call the new user's account "User B." To be clear, I want User B to have the ability to log in to her account, to use the computer, but to be unable to access any of the files in the User A account on the same machine. Currently, User B cannot use Windows Explorer to navigate to the location C:\Users\User A. However, by simply using Windows Search, User B can easily find and open documents saved in C:\Users\User A\Documents. After opening a document, that document's full path appears in "Recent Places" in Windows Explorer, and the document appears as a file that can be opened using the "Recent" feature in Word 2010. This is not the desired behavior. User B should not have the ability to see any documents using Windows Search or anything else. I have attempted to set permissions using the following procedure. Using an Administrator account, navigate to C:\Users and right-click on the "User A" folder. Select "Properties." In the "User A Properties" window that appears, click the "Security" tab. Click the "Edit..." button to change permissions. IN the "Permissions for User B" window that appears, under "Group or User Names," select User B. Under "Permissions for User B", check the box under the "Deny" column for the "Full Control" row. Ensure that the "Deny" box is automatically checked for all the other rows, and then click "OK." The system should then begin working. The process could take several minutes. When I followed this procedure, I received several "Access Denied" errors, suggesting that the system was unable to set the permissions as I had directed. I think this might be one of the reasons why User B is still able to access files in User A's account folders. Is there any other way I could accomplish my goal here? Thank you.

• Random servers in Citrix servers suddenly bluescreens (mostly 0x0000008e and 0x0000007e)

  - by Rasmus Rask

  I'm responsible for a Citrix Presentation Server 4.5 farm. Starting Friday 30. November, my servers started to crash randomly. So far we've experienced 80 crashes, so it's obviously becoming an increasingly big problem for us. I have 12+ years experience with IT, so I know the difference between 0 and 1, but I have a hard time cracking this. We've rolled back any recent changes I can think of for different groups of servers, but all groups still seem to crash. I don't have the skills to interpret the memory dumps to find the culprit. Has anyone encountered the same or a similar problem? - might be a generic Windows issue Other than executing "analyze -v" in WinDbg, how do I work my way through the memory dumps to see what actually triggered the BSOD? Any suggested steps in getting to the bottom of this? Any help is greatly appreciated. I can also provide links to kernel memory dumps or WinDbg output if necessary. Thanks! Problem description The majority of the STOP errors we encounter are: 0x0000008e KERNEL_MODE_EXCEPTION_NOT_HANDLED (50%) 0x0000007e SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (26%) 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA (21%) We also see a few 0x0000000a IRQL_NOT_LESS_OR_EQUAL (3%). For both 0x0000008e and 0x0000007e bug checks, the exception code is 0xc0000005 (Access Violation). When opening dump files in WinDbg, most details are exactly the same, for all the 0x0000008e and 0x0000007e bug checks respectively: 0x0000008e Exception address: 0x808bc9e3 Trap frame: [varies] FAILURE_BUCKET_ID: 0x8E_nt!HvpGetCellMapped+97 Probably Caused by (IMAGE_NAME): ntkrpamp.exe 0x0000007e Exception address: 0x808369b6 Exception record address: 0xf70d3be0 Context record address: 0xf70d38dc FAILURE_BUCKET_ID: 0x7E_nt!MmPurgeSection+14 Probably Caused by: memory_corruption About 30% of the crashes happens between 17:00 and 19:00, which leads me to believe this tend to happen more often during logoffs. But then again, only ~15% occurs between 15:00 and 17:00. Summary of farm Citrix Presentation Server 4.5 R06 on Windows Server 2003 R2 SP2 All high priority patches, at least as of October installed Virtualized using VMWare ESX/vSphere 4.1 on HP Proliant BL460c G6 blade servers About 53 Presentation Servers in production, divided into three silos - only one of which, the largest, is affected 2 vCPU's (5 GHz reserved), 8 GB RAM (all reserved) for each Presentation Server Plenty of free disk space Very few printer drivers - automated deletion of non-approved drivers every night ~1.000 peak concurrent users, which is reached at around 10:30 (on weekdays) Number of sessions steadily decline between 15:00 and 19:00 to ~230

• Firefox 3.5.6 causes entire computer to freeze

  - by Anthony Aziz

  Here's the situation: Environment: Just installed a fresh copy of Win7 Pro 32-bit to NTFS partition on 750GB SATA drive Hardware: E8400 3GHz ASUS P5QL Pro 4GB DDR2 1066 RAM EVGA 9800 GTX+ Plenty of cooling, no problems with hardware before Data is stored on a separate partition, including My Documents No security software is yet installed No extensions installed yet Problem: While using Firefox, sometimes the entire computer will freeze/hang. I get no mouse or keyboard input, can't CTRL+ALT+DEL, no "not responding" indication, just a static image on my display. My drivers are all up to date as far as I'm aware (I just installed this copy of Windows last week). I first noticed this when trying to install Xmarks. I went to the Xmarks site and tried to install and it would freeze. I managed to get it installed (Safe mode and the Mozilla addon site worked), but when I go to configure it (log in, etc), the computer freezes. I don't think it's a matter of usage time or memory issues, because while testing, I browsed wallpaper galleries for about 30 minutes, sometimes as many as 12-15 tabs open at a time, without issue. Sometimes I won't even try to install Xmarks at it will hang. I can install (some) other extensions, the only one I've tried is download status bar (which works). What I've done to try to fix: Restarted (duh) Windows safe mode Completely remove Firefox and install it to a new directory, according to Mozilla's KB (I haven't tried the profile manager, though I assume this does the same thing, except perhaps more thoroughly) Some BIOS changes, including Power options, disabling oveclocking (it was a modest overclock on the CPU, which has run Win7 beta and RC for almost a year now) Memtest Used another Windows user profile, same tragic results I'm STUCK now, with no idea what to do. I'm using Chrome as my main browser at the moment, but that's not something I want to be stuck with. I like Firefox and want to use it. I'm going to try creating a new profile first. One thing I did notice: I started leaving task manager and performance monitor open when anticipating (but dreading) a freeze. firefox.exe had low CPU and low memory, but it looked like overall disk usage was seeing some spikes on the small graph Performance Monitor gives you. I saw on one blog post a fellow using XP moved his Local Settings directory from a separate drive to his main drive, and that solved it, but I don't think my AppData directory is on my D: drive, and that's on the same physical device anyways. Still, something that might be worth trying. I'd extremely appreciate any help. Thanks very much. I really don't want to reinstall Windows from scratch again :( Anthony Aziz

• swapping or thrashing with vast amounts of unmapped pagecache

  - by Marco

  EDIT: I noticed that this is more appropriate for superuser.com, I apologize. I don't know how to delete this question. I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive. For example, right now the system is working (albeit a tad slow), with only firefox and wing ide running, and I have 2Gb cached with only 45Mb mapped: $ free total used free shared buffers cached Mem: 3346388 3247328 99060 0 8416 2117980 -/+ buffers/cache: 1120932 2225456 Swap: 2144668 519448 1625220 $ cat /proc/meminfo MemTotal: 3346388 kB MemFree: 97128 kB Buffers: 7872 kB Cached: 2120224 kB SwapCached: 413860 kB Active: 2304596 kB Inactive: 865984 kB Active(anon): 2279168 kB Inactive(anon): 830236 kB Active(file): 25428 kB Inactive(file): 35748 kB Unevictable: 32 kB Mlocked: 32 kB HighTotal: 2492940 kB HighFree: 5456 kB LowTotal: 853448 kB LowFree: 91672 kB SwapTotal: 2144668 kB SwapFree: 1625244 kB Dirty: 84 kB Writeback: 0 kB AnonPages: 629304 kB Mapped: 45768 kB Slab: 45600 kB SReclaimable: 21756 kB SUnreclaim: 23844 kB PageTables: 4468 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 3817860 kB Committed_AS: 3735020 kB VmallocTotal: 122880 kB VmallocUsed: 9352 kB VmallocChunk: 66600 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 888832 kB If I try to drop the caches, little happes: # sync ; echo 3 > /proc/sys/vm/drop_caches ; free total used free shared buffers cached Mem: 3346388 3220580 125808 0 3020 2100600 -/+ buffers/cache: 1116960 2229428 Swap: 2144668 519356 1625312 Right now I've vm.swappiness = 5, but I've tried also with 0 and 1 (without noticeable differences).

• No network upsets gnome

  - by Darren Cook

  An issue that has been bothering me for over a year now. My notebook, running ubuntu 10.04, is almost all the time using a wired connection, with static IP address. And a remote DNS server. Network is configured with entries in /etc/network/interfaces and /etc/resolv.conf, rather than whatever the gnome UI tool was (*) But if I'm out, or simply unplug the network cable, a few things get weird. Specifically the gnome-panel stops working - it is still there, but isn't updating. And opening a nautilus window (e.g. to look at files on the local disk) has huge time-outs. By that I mean it will not open the window for something like 30 or 60 seconds; but when it does finally open it I can see the files and it is perfectly usable. Everything else works fine, alt-tab between windows, etc. I use the commandline to find the pid of gnome-panel, kill it, wait a couple of seconds, and it opens up a fresh panel which is normally usable. (Something like 10 minutes later it will have locked/crashed again; the same for the nautilus windows.) I'm guessing this is a DNS issue? Would setting up a local DNS server help? Guess number 2 was related to having a file server mount (samba, though running on another linux box), and symbolic links to files and directories on that file server on my desktop. My question is a bit vague... Does anyone recognize these symptoms, and have a suggestion? Or do you have some troubleshooting suggestions for narrowing down the problem? My /etc/hosts: 127.0.0.1 localhost 127.0.1.1 myhost # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts 127.0.0.1 testsite.local #Other test website URLs here UPDATE: Some timings to open some desktop folder icons. This is after pulling out the network cable. A sub-directory of the desktop took 23 secs to open up. Content appears immediately (just 8 files, it has no further subdirectories). The home directory icon took 12 seconds to open up, but then took about 30 seconds for the files to appear. I closed it and tried again. This time it took 18 seconds to open up, but then 70 seconds before anything appeared. *: I couldn't work out how to use the gnome network tool for my needs, which include 3-4 static IPs for testing virtual hosts locally.

• Linux HA cluster w/Xen, Heartbeat, Pacemaker. domU does not failover to secondary node

  - by Kendall

  I am having the followig problem with an OenSuSE + Heartbeat + Pacemaker + Xen HA cluster: when the node a Xen domU is running on is "dead" the Xen domU running on it is not restarted on the second node. The cluster is setup with two nodes, each running OpenSuSE-11.3, Heartbeat 3.0, and Pacemaker 1.0 in CRM mode. For storage I am using a LUN on an iSCSI SAN device; the LUN is formatted with OCFS2 and managed with LVM. The Xen domU has two logical volumes; one for root and the other for swap. I am using IPMI cards for STONITH devices, and a dedicated ethernet link for heartbeat communications. The ha.cf file is as follows: keepalive 1 deadtime 10 warntime 5 udpport 694 ucast eth1 auto_failback off node dhcp-166 node stage use_logd yes crm yes My resources look as follows: shocrm(live)configure# show node $id="5c1aa924-bba4-4f95-a367-6c9a58ac4a38" dhcp-166 node $id="cebc92eb-af24-4833-aaf0-672adf80b58e" stage primitive Xen-Util ocf:heartbeat:Xen \ meta target-role="Started" \ operations $id="Xen-Util-operations" \ op start interval="0" timeout="60" start-delay="0" \ op stop interval="0" timeout="120" \ params xmfile="/etc/xen/vm/xen-util" primitive my-stonith stonith:external/ipmi \ params hostname="dhcp-166" ipaddr="192.168.3.106" userid="ADMIN" passwd="xxx" \ op monitor interval="2m" timeout="60s" primitive my-stonith2 stonith:external/ipmi \ params hostname="stage" ipaddr="192.168.3.105" userid="ADMIN" passwd="xxx" \ op monitor interval="2m" timeout="60s" property $id="cib-bootstrap-options" \ dc-version="1.0.9-89bd754939df5150de7cd76835f98fe90851b677" \ cluster-infrastructure="Heartbeat" The Xen domU config file is as follows: name = "xen-util" bootloader = "/usr/lib/xen/boot/domUloader.py" #bootargs = "xvda1:/vmlinuz-xen,/initrd-xen" bootargs = "--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen" memory = 4096 disk = [ 'phy:vg_xen/xen-util-root,xvda1,w', 'phy:vg_xen/xen-util-swap,xvda2,w', ] root = "/dev/xvda1" vif = [ 'mac=00:16:3e:42:42:06' ] #vfb = [ 'type=vnc,vncunused=0,vnclisten=192.168.3.172' ] extra = "" Say domU "Xen-Util" is running on node "stage"; if "stage" goes down, "Xen-Util" does not restart on node "dhcp-166". It seems to want to try as an "xm list" will show it for a few seconds and if you "xm console xen-util" it will give a message like "copying /boot/kernel.gz from xvda1 to /var/lib/xen/tmp/kernel.a53gs for booting". However, it never gets past that, eventually gives up, and no longer appears in "xm list". Now, when node "stage" comes back online after being power cycled, it detects that "Xen-Util" isn't running, and starts it (on stage). I've tried starting "Xen-Util" on node "dhcp-166" without the cluster running, and it works fine. No problems. So, I know it works in that respect. Any ideas? Thanks!

• Accidentally Removed Permissions for the XP SP3 Registry key HKEY_CLASSES_ROOT! Workaround Please!

  - by Praveen Kumar

  This is Praveen and I am using Microsoft Windows XP SP3 Build 2600. I had problems with using Microsoft Office 2010. It was keeping on saying, "Please wait while windows configures Microsoft Office Professional Plus 2010". After seeing this link: http://social.answers.microsoft.com/Forums/en-US/outlookcontact/thread/6e9c3f2e-010a-4b74-b433-0c41548ee468?prof=required I thought of giving the Registry Key: HKEY_CLASSES_ROOT, full access permissions for Everyone. I went to the registry, right-clicked on HKEY_CLASSES_ROOT and clicked on Permissions. I added Everyone and gave Full Control to the ACL and clicked on Apply. Also I checked "Replace permission entries on all child objects with entries shown here that apply to child objects." After a long time, it said with an error, cannot replace for few entries. Now, the key, HKEY_CLASSES_ROOT has no access to any user. My system is not starting up. Some of my friends asked me to try the Last Known Good Configuration. Even that did not work out. When I tried to open in the Safe Mode, I got only one driver to load and even that didn't load well. Another friend suggested me to put the Setup disk and reinstall the OS. I tried that and after completing the "Installing Device Drivers" part, when it started "Installing Network", the system is getting restarted. Now, the setup is also half way through and even if I open in Safe Mode to try System Restore, it popped up a message saying, "Setup cannot run under Safe Mode. Setup will restart now." and the system is restarting. All my official files and my software, which I developed for Registry Security, resides in my system now. I am unable to access the system and I want it to be working to submit the project, as the deadline is this week. I had no better solutions from elsewhere. Can anyone please help me out with this issue. If it is possible to open the registry editor's stored file from another system and restore the access permissions, I hope it would solve the problem. Please do help me. Thanking You, Praveen.

• Why is Excel 2010/2013 taking 10 seconds open any file?

  - by jbkly

  I have a fast Windows 7 PC with two SSDs and 16GB of RAM, so I'm used to programs loading very fast. But recently, for no reason I can figure out, Excel has started taking way too long to open Excel files (of any size--even blank files). This is occurring with Excel 2010 and with Excel 2013 after I upgraded, hoping to solve the problem. Here a couple scenarios: If I start Excel directly, it opens almost instantly. No problem there. If I start Excel directly, and then open any Excel file (.xls or .xlsx), it loads almost instantly. Still no problem BUT if I attempt to open any Excel file directly, with Excel not running, it consistently takes 10-11 seconds for Excel to start. I get no error messages, just a spinning cursor for 10-11 seconds, and then the file opens. During the delay while Excel is trying to start, I'm not really seeing any discernible spike in CPU or memory usage, other than explorer.exe. This problem is only occurring with Excel, not Word or any other program I'm aware of. I've searched around quite a bit on this question and found various others who have experienced it, but the solutions that worked for them are not working for me. For a few people it was a problem with scanning network drives, but my problem is purely with local files; I have no network drives, and the problem persists even with all network connections disabled. Some people suggested worksheets with corrupted formulas or links, but I'm experiencing this with ANY Excel file: even blank worksheets. Others thought it was a problem with add-ins, but I have all Excel add-ins disabled (as far as I can tell). One person solved it by disabling a "clipboard manager" process that was running in the background, but I don't have that. I've disabled as many startup and background processes as I can, but the problem persists. I've run malware scans, disk cleanup, CCleaner, and installed Excel 2013. I've deleted temporary files, enabled SuperFetch, and edited registry keys. Still can't get rid of the problem. Any ideas? My system details: Windows 7 Professional SP1 64-bit, Excel 2013 32-bit, 16GB RAM, all programs installed on SSD.

• Blank Screen After Login on Windows 7

  - by Leigh Riffel

  When unlocking a Windows 7 computer the screen briefly (less than a second) goes blank before showing the screen. Abound once a month (but sometimes within a few days) when I unlock my computer the screen doesn't come back from this brief blackout and stays black. Sometimes after five minutes or so the display will come back. Other times it has been blank for over 20 minutes, so I give up and restart the computer. It seems to happen more often when the computer has been locked for a longer period of time - I lock my computer several times a day, but the problem most happens when I come in at the start of the day. I have updated my video card and monitor drivers. I have two monitors driven by the same graphics card. The computer is a Dell Optiplex 740. When the problem occurs both monitors have a green light on to indicate that they are receiving signal. I've tried unplugging the monitors from the video card and turning the monitors on and off. The screen saver is set to one that is not blank screen. The Windows power settings are set to never turn off the display. When the problem occurs there is no significant disk activity occurring. When the problem occurs I can connect over the network to the hard drive on my computer. When the problem occurs I can't connect over the network with a VNC connection. The VNC client doesn't give an error, but also won't show the screen. The task actually seems to hang as I can see the task, but there is no window for it. This problem occurred when I was running a pre-release version of Windows 7. The hard drive was formatted for release version and the problem still occurs. I've been stopping some of my always running programs to see if one of them may be the culprit, but given the span between failures that will take some time to find the problem if it will even help at all. Some programs I have always running include IE, Firefox, Outlook, Evernote, Kana Reminder, Ditto, Macro Express, Timesnapper, and DisplayFusion. Any ideas appreciated.

• MariaDB doesn't upgrade, 2 versions are installed

  - by zahorak

  I have a server running on Debian wheezy with MaraiDB and OwnCloud. Few days ago, I wanted to update the packages because of the OwnCloud updates but something went wrong.

• What is a good layout for a somewhat advanced home network and storage solution?

  - by Shaun

  My home network/storage needs are changing and I am searching for some opinions and starting points on what a good network/storage layout would be that can serve my needs for a few years into the future. I think I have a decent starting point for equipment, but I am also willing to invest fairly heavily in a solution that can last me for a while. I am a bit of a tech nerd and I have a moderate tolerance for setup of the solution. I would prefer if maintenance of the system is somewhat low once it is setup, but I am willing to accept some tradeoffs. Existing equipment: Router - Netgear WNDR3700 (gigabit) Router - DLink Gamerlounge DGL-4300 (gigabit) Switch - 16 port Trendnet green switch (gigabit) Switch - 5 port Trendnet green (gigabit) Computer - i7-950 office computer (gigabit ethernet) Computer - Q6600 quad core media center, hooked up to TV, records shows (gigabit ethernet) Computer - Acer 1810T ultraportable laptop (gigabit and N ethernet) NAS - Intel SS4200-E (gigabit) External hard drive - 2TB WD Green drive (esata) All kinds of miscellaneous network connected TV, Bluray, Verizon network extender, HDhomerun TV tuners, etc. Requirements: -Robust backup solution for a growing collection of huge family picture files and personal files, around 1.5TB. (Including offsite backup) -Central location for all user's files, while also keeping them secure from each other. -Storage for terabytes of movie backups and recorded TV, and access to them from all computers (maybe around 4TB eventually) -Possibility to host files to friends and family easily Nice to have: -Backup of terabytes of movie backups Intriguing possibilities: -Capability to have users' Windows desktops and files look the same from all network computers I am not sure if the new Windows Home Server 2011 would fit into this well, if I need a domain server, how best to organize my backups, or how to most effectively use RAID. Currently I am simply backing up all computers to a RAID 1 on the NAS box, which I was thinking could prevent a situation where I reach for a backup and find that the disk is corrupt. One possibility that I am thinking about now is simply using my media center PC with a huge RAID of hard drives on which all files are stored. Pseudo-backup of all files would be present because of the RAID, but important files would also be backed up off site via carrying hard drives to work. But what if corruption seeps into the files and the corrupted data is then backed up? Does RAID protect against this? I really want to take next to zero risks with the irreplaceable files. I can handle some degree of risk with the movies and other files. I'm looking for critiques on this idea as well as other possibilities. To summarize, my goal is high functionality, media capable, and robust backup of irreplaceable files.

• autocomplete not working on one sever, works on others

  I have Ubuntu 10.10 x64 and x86 running on various servers and auto complete works on all of them bar one. The issue: apt-<tab> would show a list of options but sudo apt-<tab> would not. After fiddling with it for a few hours i've found that /etc/bash_autocomplete did not exist. on the broken server. Copying the one from a working one it now works. but still not properly. sudo apt-get ins<tab> does not show do anything. listing the files in /etc/bash_autocomplete.d/ on the working server has about 50 files, and the broken one only two or three. i dont think that i can just copy these files though as it might show commands for things that are not even installed. TL;DR autocomplete broken, how can i fix it. Seems like its disabled somewhere, why is this EDIT: Ok, it was not ever installed... $ sudo apt-get install bash-completion Reading package lists...

• long access times and errors in iis application

  - by user55862

  I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

• Windows 7 boot problem (with colorful blinking smilies)

  - by Ishmael Smyrnow

  I put my computer (Windows 7) to sleep, and a couple hours later, tried to wake it back up, but the monitor wouldn't come back on. I did a hard reset (held power button), but I still couldn't get the monitor to show anything. I plugged it into my laptop, and the monitor works fine. I then swapped out the video card with an older one I have. The monitor came on and started showing the boot process. However, shortly after the Windows 7 animated logo came up, the screen went blank, it made this weird beeping noise, and I seen the strangest thing ever. Small, colorful blocks started to fill my screen, and flash, as if something was loading. Inside of those blocks, were smilies (like the ASCII character kind). This continued for about a minute, then the computer rebooted. It scared the sh!t out of me. I've never had a virus before, and I'm savvy enough to keep myself from one, but I'm wondering if that's what it was. I've been using computers for ages, and never seen anything quite like this. Has anyone ever seen something like this? I'm doing hardware diagnostics before trying to boot into Windows again. Hopefully I can figure this out, but I thought I would consult the SU community while I wait on these results. -- UPDATE -- I did a Memory Diagnostic, which turned up nothing. I also booted into Safe Mode no problem, and scheduled a disk check on both of my drives (I dual boot XP & 7). I was feeling good, and tried putting my regular video card back in, and the monitor won't display anything with it. Also, even though the monitor displays nothing, the system sounds like it's booting up. However, I hear a clicking in one of my hard drives that isn't there with the older video card. Could this be a problem with my hard drive, video card, or PSU? PSU makes sense, except for the fact I've been using the same setup for over a year, and the video card doesn't require it's own power plug thing.
