• Windows Server 2003 Synchronize Not Sticking

  - by lkessler

  We have a Windows Server 2003. It had Raid running on 2 disks. One disk failed and the Raid Controller failed. We replaced the disk and controller and restored everything. No data was lost. The users of that server found that there were a number of directories that appeared empty. We found that from their machine, we could right-click on the directory and select "Synchronize" and the files in the directory would now be visible to them. However, when opening Internet Explorer and browsing the web and ftp'ing to a web site, the files in the directory would vanish. We would have to "Synchronize" them again to get them to reappear. What is going on to cause this need to Synchronize and then re-Synchronize again? What do we need to do to fix this so that the directories are permanently visible?

• High I/O latency with software RAID, LUKS encrypted and LVM partitioned KVM setup

  - by aef

  I found out a performance problems with a Mumble server, which I described in a previous question are caused by an I/O latency problem of unknown origin. As I have no idea what is causing this and how to further debug it, I'm asking for your ideas on the topic. I'm running a Hetzner EX4S root server as KVM hypervisor. The server is running Debian Wheezy Beta 4 and KVM virtualisation is utilized through LibVirt. The server has two different 3TB hard drives as one of the hard drives was replaced after S.M.A.R.T. errors were reported. The first hard disk is a Seagate Barracuda XT ST33000651AS (512 bytes logical, 4096 bytes physical sector size), the other one a Seagate Barracuda 7200.14 (AF) ST3000DM001-9YN166 (512 bytes logical and physical sector size). There are two Linux software RAID1 devices. One for the unencrypted boot partition and one as container for the encrypted rest, using both hard drives. Inside the latter RAID device lies an AES encrypted LUKS container. Inside the LUKS container there is a LVM physical volume. The hypervisor's VFS is split on three logical volumes on the described LVM physical volume: one for /, one for /home and one for swap. Here is a diagram of the block device configuration stack: sda (Physical HDD) - md0 (RAID1) - md1 (RAID1) sdb (Physical HDD) - md0 (RAID1) - md1 (RAID1) md0 (Boot RAID) - ext4 (/boot) md1 (Data RAID) - LUKS container - LVM Physical volume - LVM volume hypervisor-root - LVM volume hypervisor-home - LVM volume hypervisor-swap - … (Virtual machine volumes) The guest systems (virtual machines) are mostly running Debian Wheezy Beta 4 too. We have one additional Ubuntu Precise instance. They get their block devices from the LVM physical volume, too. The volumes are accessed through Virtio drivers in native writethrough mode. The IO scheduler (elevator) on both the hypervisor and the guest system is set to deadline instead of the default cfs as that happened to be the most performant setup according to our bonnie++ test series. The I/O latency problem is experienced not only inside the guest systems but is also affecting services running on the hypervisor system itself. The setup seems complex, but I'm sure that not the basic structure causes the latency problems, as my previous server ran four years with almost the same basic setup, without any of the performance problems. On the old setup the following things were different: Debian Lenny was the OS for both hypervisor and almost all guests Xen software virtualisation (therefore no Virtio, also) no LibVirt management Different hard drives, each 1.5TB in size (one of them was a Seagate Barracuda 7200.11 ST31500341AS, the other one I can't tell anymore) We had no IPv6 connectivity Neither in the hypervisor nor in guests we had noticable I/O latency problems According the the datasheets, the current hard drives and the one of the old machine have an average latency of 4.12ms.

• How can I restore my system from WIM files?

  - by Brian Henk

  I installed another OS on my netbook and decided I want to revert back to Windows 7 Starter. I was careful to keep the recovery partition, but even when I manage to boot to it, the system just restarts a few seconds after selecting "restore." I grabbed all the files from the recovery partition onto a flash drive. I also have been able to use this drive to boot a Windows 7 install, but it was unable to find the recovery partition. These WIM files seem to be the key to installing Windows again. How can I use them?

• ThinkPad T400 backlight doesn't always turn on when booting from battery

  - by srunni

  I have a Lenovo ThinkPad T400, which I've owned for about a year. A while back, I noticed a problem in which the LED backlight would not always turn on when booting from battery. Usually, if I hold the power button down until the BIOS screen shows up, the backlight turns, but sometimes even that doesn't work. If I just press the power button and let it go right away, the backlight usually doesn't turn on. This happens before the OS (I dual-boot Linux and Windows) gets a chance to boot - the BIOS screen itself is displayed without the backlight if it fails to turn on, so the problem isn't at the OS level. Any ideas? Thanks!

• PCMCIA preventing laptop from booting up

  - by Pongus

  My friend has brought his dead laptop over. It is a Sony Vaio with Windows Vista. When booting up, it blue screens and reboots. I have tried to boot up with Knoppix and this will freeze when starting up PCMCIA. If I start Knoppix with knoppix nopcmcia it disables pcmcia and boots up fine. So I presume there is a problem with the PCMCIA controller on the laptop. My friend does not use any PCMCIA cards, so doesnt really need it. Is there anyway I can similarly disable PCMCIA so that Windows will boot up fine?

• Time Machine for Windows

  - by Kevin L.

  A simple Google search for "Time Machine for Windows" results in a flurry of different little apps. But instead of relying on forum anecdotes and advertisements, I call on the much wiser Super User beta community for some depth on this one. Having Time Machine running on Leopard is like a warm, fuzzy blanket of comfort that I never got with RAID, rsync, or SyncToy on Windows. I'm not asking the community what the "best" backup software for Windows is, but instead: Is there any true Time Machine clone for Windows, one that includes as many of the following as possible: Completely transparent, "set-it-and-forget-it" backup Incremental backups (changes only) for every hour for a day, every day for a month, and every week until the backup disk is full Ability to rebuild from this backup disk in case of main drive meltdown (the backup doesn't have to be bootable; neither are Time Machine disks) Extremely easy to use UI (target user == wife). Bonus points for a beautiful UI

• Slow file operations, possible I/O error but chkdsk says OK

  - by mikolajek

  I've recently faced a strange problem. I use Directory Opus file manager that suddenly started to report an I/O error when trying to copy files onto one of my disks. The Windows Explorer did copy those files but it was extremely slow. I run chkdsk on this drive (ca. 300GB) and it took it over two days to complete! However it reported no errors found. I run Hard Disk Sentinel that says the drive is OK. But the files still read and write extremely slow! Can anyone advise me what to do? I have a spare space I am copying my files for backup now but should I get rid of this disk? Or can I try to "heal" it somehow? Many thanks for your ideas!

• ESXi 5.1 on Poweredge 510 freezes after base-esx update

  - by goober

  Background / Problem Just experienced an issue where an ESXi host was upgraded from 5.0 -- 5.1 perfectly fine. Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully. However, on reboot, the server hangs at the "Initializing Power Management" phase. I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :) Question Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?

• HP Probook 4530s great specs, but lagging. Hard Drive?

  I have this laptop, which has a i3 processor, 4gb memory, 7200rpm hard drive. So there is nothing wrong with the specs. Even when I have no applications open, simply closing and opening windows, lags. Or opening the start menu, or dragging icons across the desktop. sometimes even the cursor lags. So I checked out the resource monitor, and the resources using disk activity are svchost Avast ------- my antivirus, but not much System (PID 4) ------ This is using a huge chunk The total disk activity fluctuates between %50 - %100

• Office 2011 Mac - Unable to save Word files, plus normal.dot alert errors

  - by Jeff D

  There are actually 3 errors here. When I open Word, I get: Word cannot open the existing global template. () If I create a file, type a character and try to save to the desktop (that I have no problems writing to otherwise), I get: Word cannot save or create this file. The disk may be full or write-protected. Try one or more of the following: * Free more memory * Make sure that the disk you want to save the file on is not full, write-protected, or damaged. () I am just saving to the desktop, and I can save excel files (or anything else) there. After the failure, if I save again, the default file name becomes: .doc...doc Weird. Finally, when I close word completely, I get: Do you want to replace the existing Normal.dotm.

• Can't add German as input language in Windows XP

  - by jdm

  I have a laptop that was brought to a computer shop for a hard disk problem. They replaced the disk and reinstalled windows XP, although the English version (the laptop has a German keyboard). I'd like to switch the input language to German. Usually I know how to do this (via "Regional and Language Options"), the problem is when I choose Languages/Details/Add... it doesn't offer me the German keyboard layout: It also uses the "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard" driver - the laptop's keyboard is a 104/105 key German version. I can't seem to change this. Did I just miss the setting, or what is going on here?

• Is it possible to retrieve lost Windows XP profile information?

  - by Simon Shaw

  I'm running Windows XP Professional on a PC which is less than a year old. About 3 months ago I got an error on boot saying windows could not find my profile. At this point it created a temp one. On this occasion I copied the temp data back into my existing profile and carried on using it. After another month it died again and, once again set me up a temp user. Each time this happens I lose everything related to my profile (desktop, start menu, etc). I ran checks on the hard disk and these suggested nothing was wrong so this seems a software issue not a disk problem. On the advice of my computer manufacturer I am now considering reinstalling Windows but just wanted to check if there's any other ideas for things I might be able to try. Any suggestions for what could be causing the problem would also be gladly appreciated.

• VMWare esxi 4.1 storage errors with MD3200

  - by Karl Katzke

  We're seeing some storage errors from the esxi logs relating to our MD3200. I'm sort of a VMWare noob and am not sure where to go from here because I couldn't find a lot of documentation on the VMWare website, and the forums didn't seem to have any posts about it with actual answers. Everything is working, but I'm trying to proactively troubleshoot this. sfcb-vmware_base|StoragePool Cannot get logical disk data from controller 0 sfcb-vmware_base|Volume Cannot get logical disk data from controller 0 sfcb-vmware_base|storelib-GetLDList-ProcessLibCommandCall failed; rval = 0x800E The ESXi boxes are connected directly via SAS to the controller on the MD3200. What do these errors actually mean, and what's a good path to start troubleshooting or solving them?

• fedora liveUSB fails, drops to debug shell

  - by evan

  Trying to install Fedora 15 via a live USB made with unetbootin. I get to the unetbootin boot menu, select Fedora-15-x86_64-Live-Desktop.is, I get to this screen, then it drops into a debug shell with the message sh: can't access tty: job control turned off. The last message is dmseg is dracut Warning: No root device "live:/dev/disk/by-label/Fedora-15-Beta-x86_64-Live-Desktop.is" found. Seems to be the same problem detailed here. Tried to try nk1eto's solution but there is no by-label directory in /dev/disk. There's by-id, by-path and by-uuid.

• Arch linux ati graphics crash after grub install

  - by Jay

  Ok, so I've had an arch linux w/ gnome 3 installed for a while now. And a while ago I installed ubuntu as another partition, I think to fix an issue that cause arch to fail. So, it was all working fine, but then I went and reinstalled grub 1 on the arch partition; Ubuntu had overwritten it on the install. Then when I tried to boot into arch it booted, but the graphics wasn't working correctly: gdm wouldn't even show, and there were weird colors instead. So, I uninstalled xf86-video-ati and then installed xf86-video-vesa. That made gdm run in fallback mode and I was able to boot to gnome 3 fallback mode (or whatever it's called). But I can't seem to get the graphics working correctly.

• Disable PXE progamatically in parallels?

  - by Stefan Lasiewski

  I'm running Parallels 4.0 on Mac OS X 10.5.8. I'm trying to create a bunch of Virtual Machines from the commandline, using the prlctl tool, like so: $ prlctl create test1 -o linux -d centos $ prlctl set test1 --device-del cdrom0 $ prlctl start test1 Now, each time I start a new VM, the VM spends time waiting for a PXE boot. I'd like to turn this off. Can I disable PXE requests using Parallels or a Parallels commandline tool? Or, can I set the boot order of a VM from the commandline?

• How to stop a Linux LVM volume group?

  - by thkala

  I am currently dealing with a multiple disk failure on a Linux LVM Volume Group that is backed up by a RAID-5 md device. One disk has been taken out completely and another one is showing a limited number of corrupt sectors, due to what seems to have been a misbehaving power supply. The problem is that once an I/O error hits, md takes the array down, since it does not have enough devices for it to be operational. Where md the only one involved, I could mdadm --stop the array and then recreate it to get all devices active again. Unfortunately, the array is a PV in an LVM volume group and I cannot seem to get the kernel to release it. vgchange -an does not seem to do anything, bar spew out a couple of I/O errors. I am obviously missing something, but how in the name of -insert-favorite-deity- do I get LVM to release the underlying PV without rebooting the server?

• RAID across SAS controller ports

  - by BlueGene

  Hi, I'm managing a HP DL360 G5 machine. It has a SAS controller with two ports. Port 1 is attached to 4 drive bays and Port 2 has 2 bays. The machine currently has 3 drives connected to Port 1 with RAID 5 configuration. I'm trying to max out the bays by adding 1 disk in port 1 and 2 in port 2. Can I group those three disks(1 disk-port, 2 disks-port 2) in a RAID 5 configuration?

• "EISA Configuration" partition

  - by jpbochi

  I have a new Alienware M17x running Vista x64. I just found out that it came with a misterious "EISA Configuration" partition. On Disk Management, my Disk 0 tells me that my HD has about 300 GB. The EISA partition has 12 GB. That's big enough to know why is it there. So, this is more of a bundle question. What is this "EISA Configuration" partition? Is it safe to remove it somehow? If so, how can I delete it? I mean join it with the primary partition, or set it as a secondary small partition.

• What type of malware can reside in windows restore?

  - by qwertymk

  I was reading aking1012's comment on How to create Windows Vista/Windows 7 Startup disk or Rescue disk or system restore points on a CD? . He says that: The first thing I usually do is disable system restore. Some REALLY nasty malware hides in there and is very difficult to delete. As far as rescue media, I make a full backup image. It doesn't directly address the question so it's a comment not an answer, but I thought it was worth noting What type of malware can hide there, and how is that possible as the restore info must be stored with a checksome to make sure it's not modified, right?

• What are the strategies available to minimise badblocks on an encrypted partition?

  - by David Andreoletti

  Let me explain my backup strategy and the problem I am facing. My current backup strategy: Open encrypted container and execute Carbon Copy Cleaner on it at least once a week. Rotate backup disks. Problem: I have an Truecrypt partition on my 1st external hard disk. I recently found out that some files on this encrypted partition cannot be read due to bad blocks (reported by Antonio Diaz's GNU 'ddrescue'). My backup strategy is ineffective in this scenario because bad blocks are discovered during backup. Possible strategy Strategy #0: Have the encrypted partition over a RAID 1 with 2 disks. Is this a suitable strategy ? Strategy #1: Do you think of any other one ? Environment: Mac OS X 10.8 External 2.5" hard disk (SATA) No RAID

• EC2 persistence of machine

  - by Seagull

  I notice that EBS-backed AMIs are much like a VMWare instances -- I can stop them and also persist them to disk, and all this is done relatively quickly. However, I believe that S3 backed machines are different. They cannot be 'stopped', but rather can only be shut-down, written to S3 disk and started up again; with at least a 15 min delay in doing so. Why the difference? How do AMI providers decide whether to use EBS or S3? If I need to stop/persist/restart machines relatively frequently, then I am implicitly limited to just the EBS-backed machines?

I read somewhere that centos cant install on 2TB disk, so i made some partiotions smaller, but it's not workin. any idea? p.s. i am going to install Proxmox on that, but Proxmox same doesnt accept 2TB disks...

  Hi, I created a kickstart file ks.cfg and then I have put that in the bootable disk*(Ubuntu 10.04)* and then added the following line to the isolinux.cfg linux ks=ks.cfg and have not removed any other lines from the isoconfig.cfg file and then while installing the installation is not automated,again it is asking for language and all. If i removed include menu.cfg or any other line from isolinux.cfg i am getting a boot error. What should i do now to automate the installation.Where should i add the boot parameters so that installation will start from the ks.cfg . Thanks and Regards Ravi Kumar
