  • Win Server 2008 Hanging on "Applying Computer Settings"

    - by revoked
    Applied ~8 updates this morning, and on reboot the server just sits on "Applying Computer Settings". I've let it sit for a max of almost 40m with no response. I hard-booted (/duck) and can get into safe-mode. From there it applies it's updates and is ok. But still on normal boot gets stuck in "applying". I've tried uninstalling the updates from safe-mode with the same reaction. Any insights?

  • TCP/IP performance tuning under KVM/Qemu

    - by vpetersson
    With more and more companies switching to public cloud services, I'm curious what you guys' thoughts are on TCP/IP tuning in the cloud. Is it worth bothering with? Given that you don't have access to the host-server, you're somewhat limited I presume Let's say for the sake of the argument that you're running three MongoDB-servers in a replica-set on FreeBSD or Linux that all sync over an internal network. I'd also be curious if anyone made any actual performance benchmarks to back up their arguments. I benchmarked the various network drivers available for KVM/Qemu here, but I'm curious what the gurus here suggest to tune further. I started playing around a bit with the tuning-recommendations as suggested over here, but interestingly enough I saw a decrease in performance, rather than an increase, but perhaps I didn't fully understand the tweaks. Update: I did a few more benchmarks and posted the result here. Unfortunately the result wasn't really what I expected.

  • PSU died, is hard drive fried? Are other components damaged?

    - by srand
    After discovering and replacing my dead PSU, I was able to boot back into Windows. Everything seems to be working fine, however, one hard drive is not. Windows 7 says that this SATA hard drive needs to be formatted before it can work. Can the data be recovered? Also, is there a way to check the integrity of the other components of my computer or assume they will work fine?

  • Hard Drive Bad Sector marking utility

    - by Kevin Boyd
    I already have Windows XP, During installing Ubuntu(dual boot) the disk drive just stuck up at one place and doesn't seem to move ahead.. Is there a disk bad sector mark utility that just marks these sectors so that the disk doesn't seek them later. I tried running Seagate Seatools on the drive but both the short test and long test fail even before they start even chkdsk /f/r doesn't seem to work as the system locks up at stage four.

  • Windows Server 2008 R2 bare metal restore to different hardware

    - by S Falken
    Scenario: I have a Windows Server 2008 R2 x64 installation whose main disk drive is now 7 years old and showing signs of age. For the last couple of months it's been displaying increased errors and requirements to run checkdisk. I have successfully created a bare metal restore (BMR) image on a separate data drive on the server, which can be seen from the Windows Recovery console; I tested it by booting to and using the Windows Server installation DVD's recovery utilities. The BMR image includes the system drive with boot partition, system state, and the D:\ drive of the server, which is where I have followed the practice of installing any program that does not require a C:\ installation path. Therefore, the BMR includes both the C:\ and D:\ drives, system state and boot partition. The C:\ drive is a 7-year old Seagate 160GB. The D:\ drive is a rather newer 120GB Western Digital. I have purchased a 128GB solid state Samsung 830 that I want to restore these partitions to, using the BMR. Questions: In the above-referenced article, Microsoft seems to be indicating that I am only able to restore to like-kind hardware, which doesn't help at all and is difficult to believe. Is this really true? I've cleaned these drives up and minimized the size of partition they require. C:\ will need about a 70GB partition, and the data on D:\ will need about 50GB. Will Windows Server backup allow me to restore the BMR to newly-created partitions on the SSD, discarding extra space? I don't need a "how-to": I just need an "is it possible". Justification: Before posting this question, I checked ServerFault articles with the following titles, but none of them were about this exact scenario: Restore SBS 2008 Backup to Same Hardware but Different Disk Configuration Restoring Windows Server 2008 to different hardware - OEM License Restoring II6 server after a hardware failure windows 2008 r2 fail to restore Domain controller failed to restore using windows backup tools How does restore to dissimilar hardware work? Migrating Windows 2008 R2 from a PC to a different PC TFS 2005 Server restore from one hardware to another I also researched Microsoft but only received an oblique answer which was not precisely aimed at my question, at the following URL: http://support.microsoft.com/kb/249694#method3

  • df shows negative values for used

    - by GriffinHeart
    Hey everyone, first question around here. I have a centos 5.2 server and running df -h i get this: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 672G -551M 638G 0% / /dev/hda1 99M 12M 82M 13% /boot tmpfs 2.0G 0 2.0G 0% /dev/shm that space wasn't even near 10% usage the last time it showed a correct value, i'm at a loss with whats going on. Thanks.

  • After upgrade to Lucid, computer doesn't respond to clicks or pressed keys until X restart

    - by Victor Stanciu
    I upgraded to Lucid today, and after the update the display is "frozen". I can move the cursor, but I cannot click on anything, nor does it respond to any keys. The only way to fix it is to SSH into the machine (which, by the way, works just fine), and kill and start X. Then I'm taken back to the login screen and everything works. This happens every time I boot. Let me know if there are more details that I can provide.

  • What's a good (preferably standard) was to restore iptables config in ubuntu 9.10

    - by nixomose
    I never quite got why this isn't some built in setup, although maybe it is and stuff changes so quickly I just missed it. I can use iptables-save to generate something I can feed into iptables-restore, but what I was wondering is if there was a standard place to put it so that it gets picked up on boot without me having to add something to rc.local or the ever changing init/event.d scripts.

  • Malzilla Tutorial #4 - how to get it working

    - by Sim
    I am trying to understand the basic work flow of using Malzilla , and therefore doing the tutorials. But already in the first one, where you actually get to do something I am lost as it doesn't work for me at all, even though I follow it step by step. In the first paragraph where you have to concatenate the string and then translate it using the MiscDecoders->DecodeUCS2, I am getting not printable chars as a solution, after concatenating and using the decoder. In the second paragraph where you are told to run the script after adding the function-call at the bottom of the script, the Decoder tells me that he cannot handle the arguments.callee.toString() method and therefor wont run the script. How outdated are those tutorials and how can I get them to work?

  • Optimal way to make MySQL backups for fairly large databases (MyISAM / InnoDB)

    - by WinkyWolly
    Currently we have one beefy MySQL database that runs a couple of high traffic Django based websites as well as some e-commerce websites of decent size. As a result we have a fair amount of large databases using both InnoDB and MyISAM tables. Unfortunately we've recently hit a wall due to the amount of traffic so I've setup another master server to help alleviate reads / backups. Now at the moment I simply use mysqldump with a few arguments and it's proven to be fine.. until now. Obviously mysqldump is a slow quick method however I believe we've outgrown its use. I now need a good alternative and have been looking into utilizing Maatkits mk-parallel-dump utility or an LVM snapshot solution. Succinct short version: I have a fairly large MySQL databases I need to backup Current method using mysqldump is inefficient and slow (causing issues) Looking into something such as mk-parallel-dump or LVM snapshots Any recommendations or ideas would be appreciated - since I have to re-do how we're doing things I rather have it done properly / most efficient :).

  • linux disk usage report inconsistancy after removing file. cpanel inaccurate disk usage report

    - by brando
    relevant software: Red Hat Enterprise Linux Server release 6.3 (Santiago) cpanel installed 11.34.0 (build 7) background and problem: I was getting a disk usage warning (via cpanel) because /var seemed to be filling up on my server. The assumption would be that there was a log file growing too large and filling up the partition. I recently removed a large log file and changed my syslog config to rotate the log files more regularly. I removed something like /var/log/somefile and edited /etc/rsyslog.conf. This is the reason I was suspicious of the disk usage report warning issued by cpanel that I was getting because it didn't seem right. This is what df was reporting for the partitions: $ [/var]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 511M 8.9G 6% / tmpfs 5.9G 0 5.9G 0% /dev/shm /dev/sda1 99M 53M 42M 56% /boot /dev/sda8 883G 384G 455G 46% /home /dev/sdb1 9.9G 151M 9.3G 2% /tmp /dev/sda3 9.9G 7.8G 1.6G 84% /usr /dev/sda5 9.9G 9.3G 108M 99% /var This is what du was reporting for /var mount point: $ [/var]# du -sh 528M . clearly something funky was going on. I had a similar kind of reporting inconsistency in the past and I restarted the server and df reporting seemed to be correct after that. I decided to reboot the server to see if the same thing would happpen. This is what df reports now: $ [~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 511M 8.9G 6% / tmpfs 5.9G 0 5.9G 0% /dev/shm /dev/sda1 99M 53M 42M 56% /boot /dev/sda8 883G 384G 455G 46% /home /dev/sdb1 9.9G 151M 9.3G 2% /tmp /dev/sda3 9.9G 7.8G 1.6G 84% /usr /dev/sda5 9.9G 697M 8.7G 8% /var This looks more like what I'd expect to get. For consistency this is what du reports for /var: $ [/var]# du -sh 638M . question: This is a nuisance. I'm not sure where the disk usage reports issued by cpanel get their info but it clearly isn't correct. How can I avoid this inaccurate reporting in the future? It seems like df reporting wrong disk usage is a strong indicator of the source problem but I'm not sure. Is there a way to 'refresh' the filesystem somehow so that the df report is accurate without restarting the server? Any other ideas for resolving this issue?

  • Macbook Pro + Windows: How to make external monitor default monitor for games

    - by Linux Jedi
    When I boot into Windows on my Macbook Pro, I am unable to make the external monitor the default monitor. So when I play games full screen, they automatically open up on my laptop monitor. I want them to open up on my secondary monitor. The only solution I found to this is to make my external monitor mirror my laptop monitor. I can't even close the lid of the laptop monitor because that will cause the system to go to sleep.

  • Ubuntu Server 10.10 vs. Fedora Server 14 for Mono.NET app hosting in VM

    - by Abbas
    Ubuntu Server 10.10 vs. Fedora Server 14 I want to create a web-server running Mono, MySQL 5.5 and OpenLDAP running as a VM (on VMWare Workstation). Searching “Ubuntu Server vs. Fedora Server” mostly yields flame wars and noise. There are a few good articles available but they are either out-of-date or don’t offer very convincing arguments. I know the answer is most likely to be “it depends” but I wanted to harness the collective wisdom on ServerFault and get opinions, experiences and factual information to the extent possible. My selection criteria would be (other than what is mentioned above): Ease of use Ease of development Reliability Security

  • System failure - need diagnostic recommendation

    - by Ladislav Mrnka
    I have big problem with my computer. Configuration is: Intel i7 + 6x2GB OCZ DDR3 Motheboard: Asus P6T Deluxe V2, HDD controller configured to AHCI Main drive: OCZ Vertex 2 (SSD) - contains all installed programs and system Second drive: Samsung SpinPoint - contains User profiles, ProgramData, virtual machines and databases Third drive: Samsung SpinPoint - data drive + backups OS: Windows 7 Ultimate x64 I have never had any problem with this computer until now. During weekend my computer completely crashed without any reason. Each time I tried to boot to Windows I got BSOD with message BAD_SYSTEM_CONFIG_INFO and automatic restart (I didn't install any new SW or HW). But after restart main OCZ drive was disconnected (not detected by BIOS). When I turned off and on computer, the drive was again connected. It also happend every single time I tried to repair installation somehow. It ended with some error and after restart drive was disconnected. The only thing which worked was format + fresh install. After installing almost everything I wanted to install Visual Studio 2010 Ultimate (complete installation without SQL Server Express). During installation of VS itself I always get BSOD - it is too fast so I'm not able to read description. After restart it searches for all disk drives for really long time and sometimes it changes boot drive so the system is not able to start - Bootmgr not found. After reconfiguring BIOS the system starts. There is no event describing the failure in Event viewer. Installing VS 2010 is absolutely necessary for me. I need help with diagnostic. I need to find where is the problem - I expect that the problem is in OCZ drive or in HDD controller on motherboard but I don't know how to find it. All components still have valid warranty. Can you recommend me some approach or tools to find the problem? Edit: I'm still looking for source of the problem. New information is that Windows are not able to perform check disk (Chkdsk) on the SSD system drive. After restarting it always starts checking drive and in part where files are checked it fails with BSOD - BAD_SYSTEM_CONFIG_INFO. After next restart and skipping check disk tests the system runs.
