• How to troubleshoot a hardware problem on linux?

  - by Jack

  Just to note I am not having a problem at the moment, but have had previously so it sparked my curiosity... When a computer locks up suddenly to so caps lock flashes incessantly and the only possibility to restart....how do you troubleshoot what is causing it? On Windows there would be some errors in the event log...on Linux it seems there is no opportunity for anything to be written to the log, making it hard to troubleshoot... In this case, how would you troubleshoot the problem through linux?

• What hardware is most important for video editing?

  - by Kato

  I have heard that video editing uses the processor, while gaming uses the graphics card, and the more RAM the better for both. Is this true, and is it different for certain operations, like rendering and effects?

• Hardware issue, bsod with windows xp irq and strange messages with ubuntu

  - by JP Hellemons

  I have an old Acer T160 and it used to run Windows XP. But I keep getting random BSOD's. I keep seeing IRQ conflicts. I tried to run ubuntu, which runs and keeps running. But sometimes is not responding. Also there are these popups at ubuntu 12.04 that my network cable (which is onboard) is unplugged. But I have no cable in it! and have an usb dongle for wifi. which also seems unstable. have to (auto)reconnect sometimes. So my question is: is it my mobo, power supply or something else? FYI: I had an dvd-rw station which did not open properly, so unplugged the ata and power, als removed the second harddrive. now only have sata harddrive. also removed the extra video card (ati sapphire x1600 pro) so use only onboard video now and still have these issues. EDIT Update: will try with a new PSU (power supply unit of 400watt) the old (factory) one was 300watt. and will use a usb drive which has 12.04 ubuntu on it (made with unetbootin) to format everything and re-install ubuntu. (so also delete mbr partition) will update the day after tomorrow.

• hardware: delay and distinct 'click' before hard drive access

  - by matt lohkamp

  I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

• Choosing hardware for Flash Media Server

  - by minaev

  Having read the answers in this discussion, I still would like to come up with the same question: What should I buy to run Flash Media Interactive Server 3.5? I just have slightly different boundary conditions. We plan to serve video to ca. 1,000 users simultaneously. It will be live stream, so the server will receive the stream in HD (1280x720), cache it, reformat to various other resolutions and send it to users. OS of choice is Linux, but if you say it should MS-DOS, so it will be... What would be a decent server for this task?

• Suppliers for revision-controlled hardware, long-life motherboards?

  - by jacobsee

  Has anyone had good experience with suppliers of industrial computers, specifically 'long-life, revision-controlled' motherboards? I'm found a couple of likely candidates including ITOX, BCM, and DuroPC but haven't been able to find much in the way of independent review. I'm currently using off the shelf motherboards for an industrial data-acquisition system and am trying to eliminate the problem of rapid turnover/obsolescence of motherboards.

• Minecraft server hosting hardware specifications [on hold]

  - by Andrew Wright

  I am planning on purchasing a server to rent off Minecraft game servers, largely to friends. I am planning on purchasing a 128GB RAM server to save on colocation costs (as I am likely to need more than 32GB and would have to rent 2U of space...) I am hoping for some advice about the processing power needed to deal with this level of RAM. The servers will be run in a shared environment on linux in a VM to make backups easier. The server I have in mind is dual CPU. I have been considering at the low end dual Xeon E5-2609V2 Quad-Core 2.5Ghz, and at the high end dual Xeon E5-2650V2 Eight-Core 2.6Ghz. The difference between these is 6.4 GT/s and 8 GT/s and £3000 for the lower spec server, £4300 for the higher spec. I was hoping I could get advice about whether it is worth paying for the extra/higher speed processor or if I would be wasting my money? Thank you for any help - I appreciate that this is not directly related to professional system administration.

Better integration with Windows Firewall With this upgrade, MSE is irresistible antivirus application to have on every Windows PC.

• ApplicationSettingsBase.Upgrade() Not Upgrading User Settings after Recompiling with .NET 4.0

  - by Mageuzi

  I have a C# program that is using the standard ApplicationSettingsBase to save its user settings. This was working fine under .NET 3.5. And the provided Upgrade() method would properly "reload" those settings whenever a new version of my program was created. Recently, I recompiled the program with .NET 4.0. My program's version number also increased. But, when I run this version, Upgrade() doesn't seem to to detect any previous version settings, and does not "reload" them. It starts blank. As a test, I recompiled yet again, going back to .NET 3.5. And this time, the Upgrade() method started working again. Is there a way to allow Upgrade() to work when switching frameworks? Is there something else I am missing? Thanks.

• Wix - Upgrade always runs older installer msi and fails in trying to read old msi

  - by rkhj

  I'm having a problem though with the Windows caching of the installer. I'm trying to do an upgrade and each time the Windows installer is launching the installer of the older version. And when I do the upgrade it is complaining about problems with reading the older version's msi file (because its not in the same directory anymore). I did change the UpgradeCode and the ProductCode but kept the PackageCode the same. I also have different ProductVersion codes (2.2.3 vs 2.3.0). Here's a sample of my code: <Upgrade Id="$(var.UpgradeCode)"> <UpgradeVersion Property="OLDAPPFOUND" IncludeMinimum="yes" Minimum="$(var.RTMProductVersion)" IncludeMaximum="no" Maximum="$(var.ProductVersion)"/> <UpgradeVersion Property="NEWAPPFOUND" IncludeMinimum="no" Minimum="$(var.ProductVersion)" OnlyDetect="yes"/> </Upgrade> This is the Install Sequence: <InstallExecuteSequence> <Custom Action='SetUpgradeParams' After='InstallFiles'>Installed AND NEWAPPFOUND</Custom> <Custom Action='Upgrade' After='SetUpgradeParams'>Installed AND NEWAPPFOUND</Custom> </InstallExecuteSequence> The error I am getting is: A network error occurred while attempting to read from the file: Thanks,

• Upgrade TFS 2008 to 2010 on different server

  - by Chen

  Hi, I have been looking for a way to migrate and upgrade our TFS 2008 server to 2010 server preferably without losing any data. I have been looking at the TFS Integration Platform http://tfsintegration.codeplex.com/ and also Visual Studio 2010 TFS Upgrade Guide vs2010upgradeguide.codeplex.com Looking at the document TFS Integration Platform - Migration Guidance.xps using the first link, it seems to suggest that I could preserve all the data by first migrating the TFS 2008 from one server to the other and then upgrade the TFS 2008 to 2010. Is this true? Thank you, Chen

• DB2 upgrade database Fails due to descriptor corruption

  - by Jdcc

  Hi Everyone, I've recently upgraded my DB2 9.5 to DB2 9.7, and I am unable to update my database to v9.7. The error I have been receiving is this: "SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "Packed descriptor corruption found. Please run RUNSTATS on this table".) SQLSTATE=58004" I have tried to connect with 9.5 clients that worked before the "upgrade" on other machines, but they complain about the DB not being migrated to the current version. So my DB is now somewhere in limbo between 9.5 and 9.7. Would anyone have any clever ideas on how to execute runstats on this DB without being able to connect to it? I'm not concerned so much about the data inside, as I am about the settings (name,optimization stuff, etc) Please let me know if I there is any information I left out. Thanks, Jdcc

• Add server 2008 to 2003 domain schema upgrade failed

  - by Ken

  I'm trying to add a server 2008 r2 server to an existing 2003 domain (upgraded to 2003 functionality). I've followed the steps from microsoft which are clarified by this post: 2003 DC AD upgrade to 2008 on second server migration plan While running adprep /forestprep I lost my connection and wasn't able to resume or remote control that session, so I couldn't see the end result of the command. Rerunning adprep /forestprep indicates that the process has already been completed successfully. After finishing the rest of the steps (/domainprep ... and /gpprep, etc), the 2008 server won't join. The error message is the same "you need to run forestprep first" So the situation I'm in is that I can't rerun /forestprep, but my Registry key still reads schemaVer=30. Should I have staged forest upgrades? Any ideas how to get my schema ver to 44 at this point?

• No GUI after upgrade to Ubuntu 9.10 (boots to command line)

  - by Gathris

  I have just upgraded to Ubuntu 9.10 (network upgrade using the update manager, from 9.04 which had different graphics related problems) and when I try to boot into it all I get a small Ubuntu logo, flickering text and then the tty1 command line with a logon prompt. startx gives following error: Fatal server error: no screens found I traced down a tutorial that said I needed the latest graphics drivers (Gigabyte ATI Radeon 4650 HD installed with 9.10 catalyst drivers) so I did using the 'sh' command and a USB stick (I have a working Windows partition) and it installed fine but did not fix the problem. Edit: Thanks to UK and Arjan van Bentem below I was able to understand the full error message of start x: Parse error on lone 2 of /etc/X11/xorg.conf 'nameserver' is not a valid keyword in this section Fatal server error: no screens found This has nothing to do with a graphical error (sorry if I misled anyone) but the xorg.conf file has 3 lines in it and lines 2-3 have an entry 'nameserver'. Using the nano command I commented out (using a # before the entries) the nameservers and can now boot Ubuntu. Thanks to everyone for their help.

• What can go wrong with a GLIBC upgrade?

  - by Sevenless

  I recently installed a piece of software that my group needs for a research project starting next September. Turns out the software has a known crash bug when used with glibc 2.12.1. My boss asked if we can upgrade glibc on the server that's supposed to run it. Cue my skeptical silence.... At some point, I got it into my brain that messing with glibc was about as good an idea as messing with a hungry puma; however, I've been unable to determine the source of this belief. So, if I go ahead with this: Am I doing something flagrantly stupid (e.g. I won't fix my problem, I will brick my server, or I will initiate a zombie apocalypse)? What can go wrong? What is likely to go wrong? How do I avoid the answers to 2 and 3?

• newbie hard drive upgrade question

  - by musoNic80

  I have an Acer Aspire 3500WLMi laptop. It currently has a 40gb hard drive which I would like to upgrade. Could someone talk me through the process? I've listed my concerns/queries... Can I buy and install any 2.5" SATA or IDE hard drive into this machine? Should I buy somesort of USB caddy and clone my existing drive onto the new one via USB then physically swap the drives over? My current disk is partitioned to include a small amount of space for a Ubuntu install. Will a clone keep the current partition sizes or is it best for me to repartition once I've cloned? Many thanks.

• Justifying a memory upgrade, take 2

  - by AngryHacker

  Previously I asked a question on what metrics I should measure (e.g. before and after) to justify a memory upgrade. Perfmon was suggested. I'd like to know which specific perfmon counters I should be measuring. So far I got: PhysicalDisk/Avg. Disk Queue Length (for each drive) PhysicalDisk/Avg. Disk Write Queue Length (for each drive) PhysicalDisk/Avg. Disk Read Queue Length (for each drive) Processor/Processor Time% SQLServer:BufferManager/Buffer cache hit ratio What other ones should I use?

• Complete solution to upgrade PostgreSQL on debian production server

  - by Daimon

  I'm using Debian 6 (Squeeze) in production for a couple of websites. I decided to use postgresql backports so that I could use PostgreSQL 9.0 features. I thought that it would remain 9.0 and receive updates to that major version. Unfortunetly Squueze backports were updated to PostgreSQL 9.1 so probably I won't receive updates to 9.0. I'm planning upgrading to 9.1 but I know that it's not done automatically. I've read about official pg_upgrade and debian's pg_upgradecluster, but I would appreciate complete guide to upgrade. What are steps to do (first apt-get install postgresql, then pg_upgradecluster, then remove old cluster)? List of steps would be nice. What are possible failure scenarios? How to prepare to failures and react on them? I can stop database for a couple of hours only so I want to be prepared

• Upgrade a legacy, expired RHEL 3.4.6 server to modern Centos/Scientific Linux

  - by Gabriel Tasiopoulos

  I have a machine running a legacy J2EE app. The code is not Maven-ized and it works with pretty old Java and Postgres versions. I have converted it to a VM in ESXI and I'd like to try to upgrade it to a modern, binary-compatible version of RHEL (Centos or Scientific LInux) and see if things would still work. Where should I start? Am I being too optimistic with this one? It's more of an experiment and I'm not doing it on a production machine. But given the OS is pretty old I am looking for a way to do this eventually. Many thanks

• Safe BIOS upgrade run from external USB-HDD and not native OS

  - by ecoologic

  I have a Toshiba M200 laptop which came with Windows Vista. After buying it, I replaced the OS with XP and recently I swapped the internal hard disk with a bigger one where I only have Ubuntu. So now I can boot XP from the external USB hard disk. There's a BIOS update available (2.3 against my 1.8) which I'd like to install and there's also a version for XP. Is it "reasonably" safe to install this upgrade for Windows XP (despite the original OS was Vista, the laptop model is the right one) from my external USB hard disk with Win XP?

• How to recover an interrupted 12.04 upgrade from 11.10?

  - by martin

  Ok, I will get right to the point. I was upgrading ubuntu to 12.04 from 11.10 (x64) and right in the middle of the package installation I had a freeze (not ubuntu's fault) forcing me to do a hard reset of my pc. Now the ubuntu installation is completely broken I can only get access via recovery mode. I already tried "apt-get update && apt-get upgrade" and the option to fix broken packages. Nothing changed. So I'm wondering if its possible to fix the broken packages, or maybe to restore before the upgrade? Thank you in advance.
