  • HT Link Sync Error after Ubuntu 10.04 LTS Installation

    - by marklab
    Update 1 I just assembled an exact replica of this server, and successfully installed Ubuntu 10.04 LTS in a RAID10 configuration. The success was confirmed by a login to the initial account. There must be a hardware component that is faulty. Since the error mentions HT, which I believe to be Hyper Threading, I will start with the CPUs. Please indicate if this error is more strongly associated with any other piece of hardware. Or make a recommendation of another approach that would be good for this issue. Issue I was attempting to install Ubuntu 10.04 LTS on this system with the board RAID10 configured. However, the installation failed at the partitioning stage by rebooting the system. Upon reboot, there is an error report after POST listing the following: Node0: NB WatchDog Timer Error Node1: HT Link Sync Error Node2: HT Link Sync Error ... Node7: HT Link Sync Error Press F1 to continue/resume. After pressing F1 the system will boot from the Ubuntu 10.04 LTS installation disc. However, it will fail at the same stage, and go through the same process from there. Hardware CPU: AMD OPTERON X12 6172 G34 2.1G 18MB Motherboard: Supermicro H8QG6-F HDD: WD Caviar Green 2TB 5.4K RPM Troubleshooting I disabled RAID10 on the system, and installed the Ubuntu on a single drive. It installed successfully. I then went back to a RAID10 setup and attempted to install on the system again, and was able to make it through the partitioning stage. However, upon reboot, the system reported: Error: file not found, and then booted me into the Grub Rescue console. I feel I have aggravated the problem at this point because when I attempted to install from the boot disc again, the system reboots upon hitting enter to even start the installation process. It does the same thing when trying to boot from an Ubuntu 11 disc. I have not been able to find any information on this HT Link Sync Error, which I feel may have started the problems I am experiencing now with the installation of the OS. I am also aware that Ubuntu is said not to be supported by the motherboard according to Supermicro's site. However, since I was able to install it successfully on a single drive, I do not believe it is incompatible. I would like to know a reason for why it's failing to install on/off.

  • ZFS SAS/SATA controller recommendations

    - by ewwhite
    I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One can configure multiple RAID 0 arrays and get them working in ZFS, but it impacts hotswap capabilities (thus requiring a reboot upon disk failure/replacement). I'm curious as to what SAS/SATA controllers are recommended for home-brewed ZFS storage solutions. In addition, what effect does battery-backed write cache (BBWC) have in ZFS storage?

  • Load-balancer options

    - by toolkit
    I am looking at a number of possible options for load-balancing. So far, I am constrained to the following options: DNS server load-balancer, balancing to a cluster of tomcat servers, with terracotta for session replication. Pros - don't have to buy new kit. Cons - DNS lb can keep directing to a broken server. Hardware load-balancer, direct to cluster of tomcat servers. Pros - could have second box for failover lb. Cons - expense. Apache server load-balancer. Pros - apache's lb polls for broken servers. Cons - apache server is single point of failure, plus need to buy another server. Are there any other options I should consider? Thanks. Update: Thanks for all the answers so far +1's all round. Not accepting an answer yet, to keep more ideas coming.

  • Ubuntu hardy to intrepid upgrade hung on starting bluetooth

    - by srboisvert
    I have no bluetooth. Preliminary googling indicates that is probably an issue with some usb devices. I had an external drive, a mouse and a network dongle attached. It is just stalled during the Installing the Upgrades phase - the last commands were "Creating device nodes" Cancel will leave the system in a broken state. What next?

  • LVM2 vs MDADM performance

    - by archer
    I've used MDADM + LVM2 on many boxes for quite a while. MDADM was serving for both RAID0 and RAID1 arrays, while LVM2 where used for logical volumes on top of MDADM. Recently I've found that LVM2 could be used w/o MDADM (thus minus one layer, as the result - less overhead) for both mirroring and stripping. However, some guys claims that READ PERFORMANCE on LVM2 for mirrored array is not that fast as for LVM2 (linear) on top of MDADM (RAID1) as LVM2 does not read from 2+ devices at a time, but use 2nd and higher devices in case of 1st device failure. MDADM reads from 2 devices at a time (even in mirrored mode). Who could confirm that?

  • Windows 7 x64 installation freezes on new PC build

    - by jhsowter
    Symptoms While attempting to install Windows 7 (64 bit) on my new PC build, it freezes usually at the point where it is expanding the windows image, but has frozen as early as accepting the licence agreement, and as late as just after the first restart. My specs are at the bottom of the post. So far I have tried the following to identify the problem, in rough chronological order: Tried different hard drives with different sata cables. Same symptoms. I later used a different computer to install windows on the same hard drive with no problems. Tried the RAM in different slots, and tried one RAM stick instead of two. Same symptoms. Updated the BIOS to 1.60. Same symptoms. Ran Memtest86+ with RAM in dual channel. It passed about 6 times when I left it running overnight. Used USB to install windows instead of an optical drive. Same symptoms. Change SATA configuration from AHCI to IDE. Same symptoms. Tried various different SATA ports. Same symptoms. Updated BIOS to 1.70. Same symptoms. I saw the RAM did not list my motherboard as being supported even though the motherboard did list the RAM as being supported. So I tried some Kingston DDR3 1333MHz RAM instead. Same symptoms. Other (possibly) pertinent information My CPU idles at about 30 °C. I can't tell what it gets to when it's working. When I installed the CPU, the lever which locks the CPU in place took quite a bit of force to pull down. Now I didn't just yank it down without rechecking the CPU was seated properly about 5 times, but it does seems unusual, and I wonder if the CPU was seated badly if I would see these symptoms? I am out of ideas and don't know how to diagnose any further. I suppose either the motherboard or CPU must be the problem. I am on the verge of taking it to a specialist. The Question How should I proceed from here? Is there anything I can rule out as being the source of the symptoms I am seeing? My Specs CPU: Intel i5 3570k RAM: G.Skill RipjawsX 8GB kit HDD: single 3.5" 500GB SATA or 160GB 2.5" SATA (at different times and sometime together. But no RAID or anything). MB: ASRock Extreme4 Z77 PSU: Silverstone Strider Plus 600W ST60F-P

  • How do I setup a cloud server to share and sync files on ESXi hosted environment?

    - by Manoj Agarwal
    I want to setup my private cloud network for my company for syncing and sharing files. Instead of using existing players like dropbox, google drive, amazon etc. I want to setup my own cloud infrastructure. The requirement is to easily share private data internally within the organization. I already have an ESXi based cloud environment, running several virtual machines in it. Will it be feasible and achievable?

  • Using Windows 8 with Bootcamp?

    - by Farhad Yusufali
    I am trying to install Windows 8 using Bootcamp on OSX Mountain Lion. I need a bootable CD. Does the bootable CD have to be the size of the ISO image or can it be smaller (since it only contains the installer)? If it does not in fact have to be the size of the ISO image, what's the minimum required size of the CD I insert into my drive to create a bootable CD? (i.e. the minimum size of a bootable USB is 8GB)

    Hi, my laptop does not have a DVD driver at all. But I'd like to convert my video to a DVD format (e.g. Video_TS and Audio_TS). Is there a Virtual DVD writer out there that can pretend to be a DVD+R or DVD-R or DVD-RW drive?

  • Is there a reason to use library backups if I'm backup up full disks?

    - by Ben Brocka
    In Windows Backup I can backup libraries or whole drives (or specific folders). I want a complete backup of all relevant drives. After selecting the drives, there's still the option to backup libraries: Is the backup going to do anything different if I include libraries as well as drives? Should I just backup the whole drive instead? Space used by the backup shouldn't be an issue, since I know the incremental backup is pretty smart..

  • How to disable "Attachment Execution Service" in Windows?

    - by netvope
    If I run an executable file downloaded from the Internet, Windows displays a warning that this file can potentially harm my computer. This happens even for files downloaded by Firefox (not just IE.) On networked drive, this seems to slow down program launch time a lot. From Wikipedia, I learned that the feature is called "Attachment Execution Service". How can I completely disable it? If this cannot be done, how can I instruct Firefox not to set the "downloaded" flag on the file?

  • Why no "da-doomp" (disconnect notification sound) sometimes when unplugging wireless mouse receiver?

    - by DanH
    Sometimes (maybe one case in 3), when I unplug the wireless mouse receiver on my Sony VGN-CS215J laptop, there is no "da-doomp" sound, even after a minute or two. And if I plug the receiver back in there is no corresponding "du-dump" sound and the mouse is still (immediately) "live". This can happen when the activity light is out and there's nothing obviously going on -- it's not simply that the box is too busy. Other times one gets the expected behavior (and usually I get the correct behavior if I plug the receiver back in a few seconds and then unplug it after a "failure"). The reason this is significant is that if I get no "da-doomp" then the laptop will not sleep properly -- it will go to sleep initially, but then reawaken a few minutes later inside my laptop case and proceed to run the battery down (and no doubt overheat the unit). Any ideas?

  • ShareWebDb_log.ldf is 97GB - How to reduce?

    - by pierre
    We run an SBS 2008 server with WSS. On the drive I have set aside for WSS, I'm fast running out of space due to the ShareWebDb_log.ldf file: I've tried doing to do what I've read online - change the recovery mode, backup and truncate - but I can't actually see how I do this via the SQL Server Management Studio tool. Can anyone shed any light? The database for this file does not show in the list, and I cannot expand Management SQL Server Logs (because it's too large?).

  • Prevent gnome from automatically mounting partition when clicked in nautilus

    - by bjarkef
    Hi, I have two partitions on a hard drive in my machine that are formatted as ntfs, but must under no circumstance be mounted by my Ubuntu installation (unless I do some preparation first). However nautilus happily displays the partitions, and a single click will mount them automatically. This is very dangerous behaviour, how can I hide the partitions from nautilus and prevent accidentally mounting them by a single stray mouse click? Thanks

  • Recovering OS X Mail Accounts Lost in Crash

    - by Tim
    I had a hard crash on my Mac PowerBook and when I restarted, Mail came up with only my MobileMe account still available and I cannot figure out how to restore the other eight email accounts I have. The directories in ~/Library/Mail all seem to be there. I even did an rsync of the modified .plist files from a TimeMachine backup of the directory from before the crash (unfortunately, I was on travel, so the backup is more than a week old and I'd like to try and recover from that point without having to entirely restore from TimeMachine). I also did a fix permissions. So my questions are where exactly is the account information for Mac Mail kept? Any thoughts of what might have caused the failure? Why does only MobileMe come up? Any other thoughts on how to fix things?

  • Are there any generic KVM over IP cards/chips for motherboards without any such capability?

    - by eek142
    I have a remote server that doesn't have any IP KVM capabilities, meaning I can't remotely power cycle it or access the BIOS. I saw that ASUS offers something for their motherboards here: http://www.asus.com/Server_Workstation/Accessories/ASMB5iKVM/ But is there anything like this available for other motherboards? Even something that I could stash away somewhere in a hard drive bay that simply plugs into the board would be great.

  • MS Server 2003 Activiation Loop

    - by RPGonzo
    Recently we had a motherboard failure on a terminal server so we replaced the faulty motherboard, re-setup the RAID arrays (same motherboard but still wouldn't recognize old RAID setup) and continued to recover the system from a previous backup. No problem up to here, after restoring the system you are prompted to reboot and than login. On login we get a message box stating that Windows needs to be activated do you want to activate now, press yes but than the OS proceeds to log you off and do nothing at all. You can try over and over but to no avail. Found a few articles about a glitch in the activation script and how to reset it, tried that with the same results. Hoping someone can share some knowledge if you have seen this before? Thanks!
