• How to utilize 4TB HDD, which is showing up as 2.72TB

  - by mason

  I have two internal HDD's. They're both 4TB capacity. They're both formatted with the GPT partitioning scheme, and they're Basic Discs (not dynamic). I'm on Windows 8 64bit. I have UEFI, not BIOS. When I view the discs in Computer Management MMC with Disk Management, they show that each partition is formatted as NTFS and takes up the entire drive. And it shows that each drive has a capacity of 3725.90GB in the bottom section of Disk Management, but 2.794.39GB in the top section. When I view the discs in "My Computer"/"This PC" they only show up as 2.72TB, which matches the amount capacity I'm getting from some other 3TB HDD's I have. Why are they showing up as only 2.72GB? Will I be able to use the full 4TB capacity? Also of note, although I'm not sure it's relevant: I often get corrupted files on these two HDD's. None of my other HDD's give me corrupted files. Usually the problem is fixed by running chkdsk /f on the drives, but it's extremely annoying. In the picture below, it's the X: and Y: drives. Steps I've tried Flashed latest BIOS (MSI J.90 to K.30)

• Run script before shutdown/restart

  - by dtbarne

  I'd like to run a PHP script when an instance is told to shutdown, but of course before it actually finishes shutting down. My particular script is just looking to push some log files from the local partition to a another server. I've got the gist of how this process works, but I need some clarification. How I understand it. Please correct me if I'm wrong. Create an executable script in /etc/init.d (lets call it /etc/init.d/push-logs) Create a symlink to /etc/init.d/push-logs from /etc/rc0.d (shutdown) and /etc/rc6.d (reboot). The name should be KXXpush-logs Here's my questions: Of course - am I understanding correctly? For #2 above - it sounds like the lower the XX the better - is there too low a number I can use? Does it matter if it shares a number with another script? Does the script in /etc/init.d/push-logs HAVE to follow the standard init.d template (supporting start/stop, etc. commands)? This doesn't really apply to my use case. If possible I just want the script to be the following: #!/bin/sh # # Run PHP file prior to shutdown # /usr/bin/php /path/to/php_file.php

• Backing up VMs to a tape drive

  - by Aljoscha Vollmerhaus

  I've got myself one of these fancy tape drives, HP LTO2 with 200/400 GB cartridges. The st driver reports it like this: scsi 1:0:0:0: Sequential-Access HP Ultrium 2-SCSI T65D I can store and retrieve files like a charm using tar, both tar cf /dev/st0 somedirectory and tar xf /dev/st0 work flawless. However, what I really would like to backup are LVM LVs. They contain entire virtual machines with varying partition layouts, so using mount and tar is not an option. I've tried using something like dd if=/dev/VG/LV bs=64k of=/dev/st0 to achieve this, but there seem to be various problems associated with this approach. Firstly, I would like to be able to store more than 1 LV on a single tape. Now I guess I could seek to concatenate the data on the tape, but I think this would not work very well in an automated scenario with many different LVs of various sizes. Secondly, I would like to store a small XML file along with the raw data that contains some information about the VM contained in the LV. I could dump everything to a directory and tar it up - not very desirable, I would have to set aside huge amounts of scratch space. Is there an easier way to achieve this? Thirdly, from googling around it seems like it would be wise to use something like mbuffer when writing to the tape, to prevent what wikipedia calls "shoe-shining" the tape. However, I can't get anything useful done with mbuffer. The mbuffer man page suggests this for writing to a tape device: mbuffer -t -m 10M -p 80 -f -o $TAPE So I've tried this: dd if=/dev/VG/LV | mbuffer -t -m 10M -p 80 -f -d 64k -o /dev/st0 Note the added "-d 64k" to account for the 64k block size of the tape. However, reading data back from a tape written in this way never seems to yield any useful results - dd has been running for ages now, and managed to transfer only 361M of data from the tape. What's wrong here?

• Trying to run QEMU with a file as hda

  - by Felix

  I'm trying to run QEMU and use a simple file on the host system as the guest's hard drive. Here's what I attempted so far: $ dd if=/dev/zero of=/home/felix/vm/archlinux.img bs=1MB count=8192 8192+0 records in 8192+0 records out 8192000000 bytes (8.2 GB) copied, 86.6054 s, 94.6 MB/s $ qemu -hda /home/felix/vm/archlinux.img -cdrom archlinux-2009.08-netinstall-i686.iso -boot d Then I try to install Archlinux to that file. It goes pretty well (it's able to format it from what I can tell) until I start installing packages, when I get errors like this: And, of course, everything goes downhill from there (unable to mount the partition, corrupted files, ...). What am I doing wrong? Note: I'm just doing this for entertainment purposes. I don't intend to actually use this on servers or anything. The only use I can think of for this kind of installation would be to actually get an 8GB USB stick and dd that file to it and wham! You have a bootable stick with a fully fledged and customized OS, and without torturing the stick through the installation.

• Install Ubuntu 10.10 from loopback mounted ISO image

  - by Zifre

  I have a laptop with a faulty BIOS that has stopped booting from CDs even though it supports it (and it doesn't support booting from USB drives). I am trying to install Ubuntu 10.10 on it. I already had 9.10 installed. I tried using Kexec, but it refused to accept the kernel image. Eventually I found this page which shows how to make GRUB 2 boot from an ISO file. That worked fine, and I am now running the live image from the file. (If I can get this to work, it will be my new preferred way of installing Ubuntu, as it saves CDs and boots much faster.) However, I can't install it. The installer won't make changes to the hard drive, because the partition containing the ISO is mounted (and can't be unmounted because it is in use). Even if I only choose to use other partitions that are not mounted, the installer refuses to go any farther. Clearly, it should be possible using other partitions on the same disk. Is there any way to work around this issue or force the installer to go ahead?

• Red Hat 5.3 on HP Proliant DL380 G5 and failed drive on RAID controller

  - by thinkdreams

  I have a development ERP server here in my office that I assist with support on, and originally the DBA requested a single drive setup for some of the drives on the server. Thus the hardware RAID controller (an HP embedded controller) looks like: c0d0 (2 drive) RAID-1 c0d1 (2 drive) RAID-1 c0d2 (1 drive) No RAID <-- Failed c0d3 (1 drive) No RAID c0d4 (1 drive) No RAID c0d5 (1 drive) No RAID c0d2 has failed. I replaced the drive immediately with a spare using the hot-swap, but the c0d2 continues to mark itself as failed, even when I umount the partition. I'm loathe to reboot the server since I'm concerned about the server coming back up in rescue mode but I'm afraid that's the only way to get the system to re-read the drive. I assumed there was some sort of auto-detection routine for this, but I haven't been able to figure out the proper procedure. I have installed the HP ACU CLI utilties, so I can see the hardware RAID setup. I'd really like to find out what the proper procedure should have been, where I went wrong, and how to correct it now. Obviously this goes without saying I should NOT have listened to the DBA and set the drives up as RAID-1 throughout as was my first instinct. He wasn't worried about data loss, but it sure would have been easier to replace the failed drive. :)

• Get details / solve issue with a kernel panic?

  - by Joseph

  I have a Lenovo T430 running Linux Mint 13 (MATE): joseph:~$ uname -a Linux joseph-T430-LM 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I installed Mint immediately after getting the laptop about two weeks ago, and have noticed that about once a day, the computer will completely freeze up- I can't use Ctrl+Alt+Backspace to restart X, I can't use Ctrl+Alt+F1 to get a text only terminal, can't move mouse, can't type, and if any music was playing it just gets stuck in about a 1-second loop. There is a Windows partition, but I haven't had any issues in Windows. I couldn't find a common thread between the freezes, they were seemingly random (sometimes right after I clicked the mouse, sometimes not; sometimes with Pandora/flash being used, sometimes not, etc). I assume they're kernel panics since it completely locks up, but the laptop doesn't have a capslock or scroll lock LED. It is on a dock and I do have a USB keyboard, but the scroll lock/capslock lights do not flash when it happens (not sure if this is indicating its not a kernel panic, or if the kernel panic just wouldn't illuminate the LEDs on a usb keyboard attached to a laptop dock). This was annoying but not terrible. However, I've found a way to reproduce it. I have a particular CSV file that when I open up in LibreOffice Calc and scroll around, the same thing happens- complete lock up. I really need to use this file, so I'd like to fix the issue, but at the least it's given me a test case to work with. So, having a case where I can cause this issue, what can I do to better find out what's going on? I've looked in /var/log/syslog but haven't found anything seemingly useful. Any thoughts?

• I used disk copy to clone my drive, now my windows 7 profile won't load correctly

  - by RzK

  I used easeuse disk copy, after acronis, clonezilla, windows image restore failed me. Basically it copys all sectors, I set it to skip bad sectors(40). The source drive works, it just gave me a couple errors and stopped booting at one point. The drive is an identical copy, minus 40 bad errors. The drive is set to C and active partition, I rebuilt the boot order. I've ran sfc /scannow and ran chkdsk /r chkdsk found 20kb of bad sectors if I remember right. Now the issue I get is when I log into my profile which was saved right, I get a blank light blue wallpaper (non-license) explorer.exe is not running, and there are only 4 processes running in taskmanager, including taskmanager. I would try a repair install but CRTL-E would not open, nothing will open once I force start explorer.exe, almost like all services are down. What should I do? Fresh install is almost not a possibility I will try and fix this issue. sfc /scannow /offbootdir=c:\ /offwindir=c:\windows returns "Windows Resource Protection could not perform the requested operation"

• Windows 32-bit and 64-bit and GPT

  - by MrLane

  I know similar questions have been asked before across several sites, but the answers at least to me have been confusing and conflicting. My understanding has always been that 64-bit Windows will create and use GPT disks just fine, but will not boot from them without a UEFI BIOS. Also my understanding WAS that 32-bit Windows could not use GPT at all and so is always restricted to 2.2TB disks, which was another reason to move to 64-bit on top of the 4GB memory limit. But I have now read that this isn't correct: 32-bit Windows will create and use GPT disks just as 64-bit does. The only resriction is that you can't boot 32-bit Windows even if you DO have a UEFI BIOS? I don't think much of the literature has explained this well. There are several tools floating around for creating virtual disks or 2.2+.8GB partition schemes and such for 32-bit systems. Why when it seems you can use GPT in 32-bit Windows anyway. It also seems that people blame MS for lagging behind with respect to all of this: but it seems the issue is with BIOS manufactures not supporting UEFI rather than MS not supporting GPT... Is my new understanding now correct?

• Does Hyper-V support SCSI Pass-through discs in a Server 2003 R2 VM?

  - by Peter Bernier

  I'm running into some difficulties getting pass-through disks to be accessible to a Hyper-v server 2003 r2 virtual machine. Host OS : Server 2008 R2 full w/Hyper-V role Guest OS : Server 2003 R2 (Windows Home Server) The guest's OS disk is a pass-through disk on the IDE controller (not the best solution, but I can live with it). My storage disks will be pass-through disks on the SCSI controller. I'm able to see all of the disks that I'll be using for the VM on the host without issue. The problem that I'm having is that I can't seem to get the guest OS to be able to 'see' the storage drives (as pass-through disks on the SCSI controller). Here's what I'm doing : On the host, the storage drive is set to 'Offline' just like the OS disk (this is required for pass-through to work). In the VM, the storage drive is on the SCSI controller. Hyper-V Integration Tools are installed in guest. That's as far as I'm able to get. I don't see the drive in Computer Management, or in Windows Explorer (I've tried with an unformatted disk, as well as after formatting a partition). I am able to see a removable device that lists the disk's model number in the Guest, but I can't seem to access the storage. (I get an entry in Device Manager that needs drivers, but nothing on the Integration Tools disc works..) Trouble-shooting steps I've tried : If put the pass-through drive on the IDE controller, I can see it in the Guest. If put the storage drive 'Online' in the host and create a VHD on it on the SCSI controller, I can see it in the Guest. I suppose I could create a fixed-size VHD that consumes the entire disk, but I'd rather not have that overhead. I've also extracted the contents of the Integration Tools drivers (x86 and amd64) and tried pointing the disk controller to each of those, with no luck. Can anyone offer suggestions as to how I can get this to work properly?

• Compaq R4000 laptop randomly locking up

  - by Josh

  I have a Compaq R4000 laptop with 2GB of RAM, running Ubuntu Linux 9.10. It is randomly locking up on me, approximately once every two days. I have a second partition with Windows XP Home installed, and I have had the system lock up in XP as well, meaning I believe this is a hardware issue. I have run two passes of Memtest86+ with no errors. The system has a fan that has died, so I initially suspected overheating. However the system just locked up on me while I was in the middle of typing a script to warn me / shut down if the temperature was too high. When the lockup happened the temperature was 88°F, so I am now starting to believe that may not be the issue. When the system locks up, I cannot SSH in nor ping it. Nothing shows in syslog when I reboot. I have configured it to send syslog messages to a local server as well and no messages appear on that server when the lockup happens. I am open to any and all advice!

• Looking for a comprehensive/"expert" guide to BCD parameters

  - by Stilez

  I'm interested in educating myself about BCD on Windows 8. There are many, many "walkthrough" guides" and "howtos", but I can't find any guides at typical "enthusiast" level covering what each option or argument in a BCD /ENUM dump might mean, and the principles governing how these all work together. Imagine trying to rebuild or debug BCD (including EFI/BIOS variants and recovery/hibernate/memtest sections, and perhaps multiple boot Windows/WinPE/WinRE) from scratch using just BCDedit + DiskPart, and trying to understand rather than just copy/pasting commands. That's roughly the knowledge I'm after. Example questions might be: How is a BCD /ENUM dump to be read, item by item? How do its sections work together? (A lot of guides only show a specific example rather than explaining all the all common args that can exist and what they mean, they don't actually explain how sections work together, or they assume MBR/BIOS/Vista/7 and omit info needed for EFI/GPT/Dynamic disks/8) Partitions are specified by volume letter or as a \Device\HarddiskVolumeNNN. Why does it sometimes show these items as a letter and sometimes as a GUID? What are the practical differences if any? What exactly is syntax like "ramdisk=[C:]\Images\winpe.wim,{ramdiskoptions}" saying, and how will the drive letter "C" be interpreted at runtime in a line like this? Is the drive in such a line always "C:" (most examples assume so) and if not, when wouldn't it be? Many websites state that an sdi device and path may be needed in some sections of BCD, but what is sdi and what are these args doing when they appear? How does the GUID to HDD volume/partition mapping work under EFI/GPT? So that if disks or partitions/volumes change it's clear how one can confirm from basic principles whether data shown in BCD /ENUM ALL is still correct or not. Does anyone know of a suitable reference source for this kind of raw BCD data and structures? Thanks!

• Best option for storage clustering

  - by sam

  I'm working on an application that requires a large amount of storage space and I want to handle storage 'in-house' (Much cheaper than, say, S3) so we will have multiple servers (Initially 4) with large amounts of storage (6TB each). The storage will need to be very flexible and configurable, each piece of data should be replicated on at least 2 servers and must be easily readable/writable from ether an API of a UNIX device/file/folder like a normal drive, I don't mind which. We must also be able to easily offload content to our HTTP CDN (Edgecast), it doesn't need to have built in HTTP support but if it doesn't I'm going to have to write something to get the files onto HTTP so they can be pulled by the CDN. I've looked at a lot of solutions including Eucalyptus Walrus OpenStack Object Storage MogileFS and some others which I can't remember All the servers will be running RHEL 6, they have 4x1.5TB drives which will be RAID1'd into a single partition. All the servers have 1GB/s connections between them and 100MB/s connections to the internet with unlimited bandwidth. They have 2x2.66ghz processors. I understand there isn't a single, perfect answer but it would be nice to get some pointers.

• Ubuntu 10.04 Keyboard and Mouse Freezing Problem

  - by nitbuntu

  I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

• Data recovery on a corrupted 3TB disk

  - by Mark K Cowan

  Short version I probably need software to run a deep-scan recovery (ideally on Linux) to find files on NTFS filesystem. The file data is intact, but the references are no longer present. Analogous to recovering data from a "quick-formatted" partition. Hopefully there is a smarter way available than deep-scan, one which would recover filenames and possibly paths. Long version I have a 3TB disk containing a load of backups. Windows 7 SP1 refused to detect the disk when plugged in directly via SATA, so I put it on a USB/SATA adaptor which seemed to work at first. The SATA/USB adaptor probably does not support disks over 2.2TB though. Windows first asked me if I wanted to 'format' the disk, then later showed me most of the contents but some folder were inaccessible. I stupidly decided to run a CHKDSK on my backup disk, which made the folders accessible but also left them empty. I connected this disk via SATA to my main PC (Arch Linux). I tried: testdisk ntfsundelete ntfsfix --no-action (to look for diagnostically relevant faults, disk was "OK" though) to no avail as the files references in the tables had presumably been zeroed out by CHKDSK, rather than using a typical journal'd deletion). If it is useful at all, a majority of the files that I want to recover are JPEG, Photoshop PSD, and MPEG-3/MPEG-4/AVI/MKV files. If worst comes to worst, I'll just design my own sector scanner and use some simple heuristic-driven analysis to recover raw binary blocks of data from the disk which appears to match the structures of the above file types. I am unfamiliar with the exact workings of NTFS but used to be proficient at recovering FAT32 systems with just a hex-editor, so I can provide any useful diagnostic information if you let me know how to find it! My priorities in ascending order of importance for choosing the accepted answer: Restores directory structure Recovers many filenames in addition to the file data Is free / very cheap Runs on Linux Recovers a majority of file data The last point is the most important, but the more of the higher points you match the more rep you'll probably get :)

• Getting Grub2 to recognize a Raid 10 boot/root

  - by xenoterracide

  I've been trying to get my raid to boot from grub2 for about 2 days now and I don't seem to be getting closer. The problem appears to be that it doesn't recognize my raid at all. It doesn't see (md0) etc. I'm not sure Why or how to change this. I'm using mdadm, 2 device (essentially a raid1) raid10,f2, which is currently degraded. I have tried adding the raid and mdraid modules with grub install along with others. I've tried several variation on grub-install such as grub-install --debug --no-floppy --modules="biosdisk part_msdos chain raid mdraid ext2 linux search ata normal" /dev/md0 I've been searching the net for an answer to what I haven't done but no luck. On my other drive which I plan on removing the raid is initialized and mounted fine on boot, but it's not the boot/root for that setup. My grub.cfg isn't recognized by grub since it can't read the raid partition so I'm not posting that. md0 is not listed in my /boot/grub/device.map.

• Windows XP Installation problems

  - by Samurai Waffle

  I'm having trouble installing Windows XP on a computer... My friend gave me her old computer, it was riddled with viruses and ran extremely slow. I did my best to clean it out, and after a bit I discovered it had a boot sector virus. So I downloaded the Ultimate Boot CD (installed it on a flash drive), and ran Darik's nuke and boot to completely wipe the hard drive. I then tried to reinstall Windows XP from a USB drive... It doesn't work. The computer just stalls and never boots. The computers dvd drive doesn't work, so I borrowed a spare drive that another friend had, and tried to run a Windows XP cd. For a bit I got the stop 7B error, but now it just stalls like the USB drive does. Since then I've booted back into the Ultimate Boot CD, and ran partition magic. Repartitioned the Hard Drive, and copied the files on the Windows cd to the hard drive. I was wondering if there is any way I can make it run the setup.exe off the hard drive. I have the UBCD at my disposal, but have yet to come up with a way to do it. Any help is greatly appreciated.

• How to "swap in" again memory from page file to physical memory in Windows at once (like linux swap-off)

  - by Arnout

  Is there a way to swap back in (to put back all the memory data that was put into the page file (or swap, whatever you prefer)) memory on a windows PC? On linux, one can easily do this with the swapoff /dev/sdaX, where X is the swap partition. On windows, it seems to ask me to reboot each time.. The reason I'd like to do this, is that, even though swapping out the data to the swap file allows me to play a resource-hungry game fully in physical ram, when I stop the game, all the rest of my programs run slow. This is or course normal; all the programs were pushed into the page file because my RAM was too small, and all memory access to those programs after gaming bumps into hard page faults, with major delays and some frustration as a consequence. However, that frustration could easily be avoided, by simply allowing the PC to copy all data back into the physical memory for a minute or so, and then resume working on a fast working PC! (rather than having to endure the slowness -while- working) Thanks in advance for any advice on this! Kind regards

• Error loading operating system: format Windows 7 to Windows XP Service Pack 3

  - by Blerta

  I saw that there are other questions like mine here. But O also saw that some problems where solved with fixmbr from a Windows 7 recovery console, but that didn't work for me. I bought my laptop with Vista installed and later reformated and used Windows 7. During formatting with Windows 7 I had some problems with my hard drive and found out it was dead so I bought a new one. I wanted to reformat with Windows XP,because Windows 7 is consuming more RAM that it is able handle and I wanted to use it for other programs. So I formatted with Windows XP Service Pack 3 but after first reboot a message appeared: "Error loading operating system" Reading here, I assumed that maybe I had installed it on the wrong partition and maybe having two OS now, so I used fixmbr but it is still not starting up. Anyway I am sure that is not the case of two operating systems. Is there any chance that when the computer designed to work with Vista you would face problems with Windows XP? Like not recognizing a hard drive?

• How to restore broken Ethernet functionality on Mac G5 running Mac OS 10.4.11 (Tiger)

  - by willc2

  I had a disk error that rendered my Mac unbootable. I repaired it with Tech Tool 4, but now networking does not work. Network Preferences reports that my Ethernet cable is unplugged. I know this is bogus because when I boot from an emergency partition, networking works correctly. Furthermore, wireless networking is also broken, which I tested with a known-good Wi-Fi dongle. Whenever I try to change Network Port Configurations by creating a New or Renaming an existing one, example: I get this message in the console: Error - PortScanner - setDevice, device == nil! Error - PortScanner - setDevice, device == nil! In sets of two as shown. When I try to invoke the Network Diagnostics app, it immediately crashes. My first thought is to reinstall Tiger with the Archive and Install method so I don't have to reinstall all my applications but I have lost my Tiger installer disk. My next thought is to buy Leopard for $107 on Amazon. If there is any way I can just repair my Tiger install I would be happy to save that money, though. This is not my main machine and I am loathe to put more money into it. How can I recover my network functionality? UPDATE: I found my Tiger install disk and tried an Archive and Install. It failed with an unhelpful error message along the lines of "Can't install, try again". I tried again but had the same error. My guess is, some corrupt or missing file in my User folder is preventing migration. I have a backup created with Super Duper that is a bit out of date but will startup the machine (with functional networking). I would love to just copy over the file(s) that got messed up but I don't even know where to look. What is the likely location of the System files that would cause the aforementioned symptoms?

• running automated fsck on remote server

  - by GriffinHeart

  I had another question about df, and now i came to conclusion i need to run fsck my partition, i've been reading about it and would like some advice, if possible. The situation is like this, no physical access to the server and i want to run fsck. from what i read i just need to touch /forcefsck and when i reboot it will run fsck. My question is, at its basis, with what arguments will the fsck run? Will it need user input to correct errors, etc? and after running will it save a log of what happened? if this was how it ran it would be perfect, anyway of enforcing that on reboot? fsck -v -p /machine/disk/p1 2>&1 > fscklog.txt Also here they describe this: it's also a good idea on debian and debian-derivatives like ubuntu to edit /etc/default/rcS on remote servers and set "FSCKFIX=yes" that adds "-y" to the boot time fsck, so it doesn't risk the remote server being stuck waiting for someone to login at the console and run fsck. But on Centos that doesn't seem to exist I only have ssh access at the moment so that is why i'm being so picky with it. here's some info about disks and mounted volumes on the server: http://pastebin.centos.org/33314 Thanks.

• Which linux distributions offer seamless support for UEFI and an LVM root out of the box?

  - by Jannik Jochem

  My new ultrabook (an Asus UX32VD) requires UEFI in order to boot from the internal harddisk. I use an LVM partition which contains my root fs and dual-boot Windows 8. I somehow managed to get this working on Sabayon Linux, however the overall process was pretty painful, and system upgrades keep breaking my configuration because everything depends on a hand-configured kernel and a hand-crafted GRUB2 configuration. This causes a lot of hassle and distractions for me, so I am considering to switch to a different distribution. However, I cannot find any concrete resources that precisely document the state of UEFI support in the popular distributions. As an example, the length of the Ubuntu wiki page on UEFI suggests that installing on UEFI systems is a non-trivial process, and this AskUbuntu thread on encrypted LVM on UEFI systems suggests that LVM might also be a problem. I know that this question seems somewhat open-ended, so I'll formulate concrete questions: Are there any Linux distributions with an installer that supports installing to an LVM root in a UEFI boot setting where Windows 8 is dual-booted? Which distributions support UEFI without having to jump through hoops in order to bootstrap into a UEFI-booted system or requiring manual configuration of the boot manager?

• restoring a failed SBS 2000 box...

  - by Brad Pears

  Hi there, I read a post where you had mentioned you have had a PERC card blow up on you in an SBS box... I've got a similar situation where one of my RAID drives failed and then the power supply failed before I could replace the drive... I then replaced the power supply and the failed drive and reconfigured the RAID array. I had a recent full backup of the my Win2k SBS's C: drive stored on my SYmantec backup exec server so I installed win2K server on the c: partition and then once I had that up and running, installed the backup exec agent so as to do a restore of the entire c drive including system state. THis all worked just fine, until I had to reboot. I received an "incorrect drive configuration" error and then it hangs. I figure that likely makes sense becasue I think my RAID array is configured slightly different now in that the partitions may be sizeded ever so slightly differently now than they were before I think... Is there a way I can just restore from my backup BUT maybe exclude some of the registry and hidden boot files it wants to restore so that it is booting with the current configuration now active on that machine - not the pre blow up configuration files? I also read a post that indicated you might have to install the exact same service pack etc... etc.. before attemting a restore but that does not make sense to me being as the entire c drive contents are going to be overwritten by the restore anyway? THe basic OS install is just to be able to get the backup exec agent installed . I can;t understand why one would need to install the exact same SP level. CAn you shed some light on what I might be able to do to get this thing up and running? Thanks,Brad

• Ubuntu 12.04 froze during update, won't boot

  - by Cichol

  I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall. My specs, to the best of my knowledge: Clevo Corp model B7130 (Sager custom) CPU: Intel Core i5 @ 2.53gHz (4 CPUs) Graphics Card: Nvidia GeForce 425m 4096 MB RAM Drivers: Whatever comes with the download of 12.04. As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?
