Red Hat :: Unable To Perform Recovery On Corrupted LVM Volume
Feb 14, 2011
I just set up a new CentOS 5 server with three identical SATA hard drives in LVM. Last week we copied all of our files to the new server and it was working fine on Friday. I came after the weekend and booted the machine back up but our new LVM isn't showing up. So I do this...
Code:
[root]# lvscan
Couldn't find device with uuid 4NmvxK-JE6K-U8cd-Br3D-W9ba-fuaI-UMoRxt.
inactive '/dev/lvm0/apps' [469.01 GiB] inherit

I've two laptops, my main one is Dell inspiron 1545 and for experimental purposes, I use Acer Aspire 5315. I used to be a Redhat linux user from 2001 to 2003 on and off, but lost touch with linux for the past few years. I grew frustrated with windows after my Vista recovery partition in Acer Aspire got corrupted and when I took the laptop for servicing, the service person installed a pirated copy of XP. The laptop constantly overheated and I always received all kinds of warnings from microsoft about using pirated version. I finally decided to buy a new laptop and hence bought Dell inspiron 1545. Too bad I didn't realize I could have switched to linux.
I was suspicious about Windows 7 in my new dell right from the day one and thought of checking linux options available. I was surprised to know the the most popular linux distro now was no longer Redhat or Suse but a relatively newcomer Ubuntu. I installed Ubuntu 9.10 on a 40GB extended partition and was extremely satisfied with the ease of installation. The hardware detector told me I need to install "Broadcom STA" for my wireless card to work. I installed ATI driver from AMD website and it worked like a charm. Like any linux user, I couldn't resist the temptation to distro hop, so decided to use my old Acer laptop as testbed. The first distro I tried was KDE version of Fedora 12. The splash screen was very impressive and more graphical than Ubuntu's, however the boot time was painfully slow and I ran into a dependency hell while trying to upgrade using Kpackagekit.
I tried Linux mint KDE next and it was impressive, but I was still not completely satisfied. I then tried Opensuse 11.2 KDE and I immediately fell in love with the beautiful look and feel. I was so impressed that I went ahead and replaced the ubuntu in my dell with Opensuse 11.2. However, it was not smoothsailing when it came to hardware detection. After a lot of trials and tribulations, I managed to download Broadcom STA drivers and managed to get my wifi working. I realized that Radeon HD was installed as default and tried to turn on compositing. KDE got stuck and even after cold reboot, didn't recover. I had to re-install the OS and this time I tried to install ATI proprietary driver. But running the driver install script threw up lot of errors and I lost my mouse cursor. I had to re-install the OS again, generate RPM for the ATI driver and install it along with Kernel source, headers, gcc, make, etc... Finally I was able to activate compositing.
I then installed Xen and when I booted to Xen kernel, my mouse cursor again dissapeared, most likely due to non-compatibility of ATI driver. I had to uninstall Xen. I then tried to upgrade the kernel to 2.6.31-15 and again my mouse cursor dissapeared. I had to re-install the entire OS again. I'm so frightened of Kernel updates now. I never had such problems with Ubuntu kernel updates, maybe ATI is more pro-active in releasing new versions of drivers when it comes to Ubuntu.
In-spite of all my hardships, I'm so much in love with Opensuse and KDE. I love it so much that it now runs on both my Dell and Acer. I've removed all the other distros from my Acer. It has been quite a long time since I tried any other distro and I don't even have the faintest desire to distro-hop. Infact, for the past few days I'm so worried about the news of Novell takeover. I really don't want Opensuse to die. It will be a big loss for Linux users.

I'm hoping, now that I've recovered my partition tables, how to rebuild my LVM volume group. The trouble is that one of the volumes lost its partition table, and after rebuilding the table, LVM can no longer identify the drive. I'm trying to rebuild the 'fileserver' volume group.
pvscan produces the following:
Couldn't find device with uuid 'jsZAMq-LSa1-87Zb-WoGs-oi6v-u1As-h7YZMl'.
PV /dev/sdc5 VG dev lvm2 [232.64 GiB / 0 free]

I am trying to install an ARM version of Ubuntu onto an SD card for a BeagleBoard from a .img file downloaded from http://releases.ubuntu.com/lucid/. I have tried several files of .img and .raw downloaded from several places. I am using 'dd' on a PC running Ubuntu 10.0.4. My question doesn't relate to the BeagleBoard at all since I never get that far. The files for Angstrom that I copy directly onto a formatted SD card boot up fine on the BeagleBoard, but I need Ubuntu on there and can't do it with these image files. The command I use is:
sudo dd if=<the downloaded file> of=/dev/sdb1 After it asks the root password, it chugs along for some time and then gives what appears to be a successful response like the following. (This time it was for the Maverick version of Ubuntu in a .raw file):
leiphasw@dell-linux:~/Downloads/ArmMaverickUbuntu$ sudo dd if=maverick-preinstalled-netbook-armel+omap.raw of=/dev/sdb1
4090632+0 records in
4090632+0 records out

Could not download all repository indexes.The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.and therefore i am unable to perform many tasks.this is a clean install of 9.10 on a brand new laptop

for some reason Win7 has gone and run a startup repair (there was two boot options in GRUB, perhaps I chose the wrong one by accident) which has corrupted my GRUB. Now, the only way I can get anything to run is by booting Ubuntu of a live-pendrive/flashdrive! I tried following a couple of walkthroughs that claimed to fix the problem; and I don't doubt that they work - on someone elses computer! I receive errors whenever I try to use things like 'sudo grub' and often (but not always) with 'mkdir' and 'mount' - and I have very little idea what some of them are doing (I gather 'mkdir' is making a directory and 'mount' is mounting a device virtually, but some others are a little harder to guess)
So, I am wondering if someone has a little insight as to how I can fix this and perhaps point me in the correct direction to learning about making my way around ubuntu and these fancy terminal commands! Currently, I am at the stage where I can boot into my flash drive by spamming escape before the bootloader. However, when GRUB loads it tells me there is an error and gives me a command line; through which I have been unable to get anything to happen. I am running Ubuntu 10.10, I believe, and Windows 7 on the same hard-disk and possibly the same partition (though, I am unsure of how Ubuntu works itself into partition's). I also ran a little code (seemed somewhat like a batchfile in windows) that made a txt file of my boot info; I'm attaching it below if that helps at all. Boot Info Results:

The Ext 4 file system of the partition (dev/sdb1) is corrupted. When I seek to repair this using the boot repair tool it is unable to resolve this. I admit that I don't fully understand the problem - except that I'm unable to open and use programs.

I installed lucid last week, and this morning installed some updates that appeared in update manager and then started having issues with permissions so I rebooted. Now when I try and log in I get the message Authentication Error Normally this wouldn't be a problem I would reboot again hit ESC just before loading Grub appeared and go into recovery mode and change the password for my master user. But I never get the chance to press ESC, and even I hold the key down from the time my BIOS flash screen is up, I never get the GRUB menu.

I broke sudo when I wrongly edited a file in /etc/sudoers.d in vi(did not use visudo :-().I read that I could fix the same by rebooting into the 'Recovery Mode' by selecting the same from the grub menu.
However I'd earlier disabled the showing of the grub menu by editing /etc/default/grub. As a result I can't seem to go into recovery mode to fix my broken sudo.

My MBP fails to boot Arch. This is what I did to install ArchLinux. Install rEFIT.
Partition using disk utility such that first one is Mac partition, second is Arch & the third ie the last one is windows.
Then put Windows 7 CD, select it from rEFIT and install it. Similar, install ArchLinux just as I did for windows.
Then finally to install the GRUB, I issued the command $grub-install --root-directory=/mnt/arch - recheck /dev/sda3 (after mounting my /dev/sda3 to /mnt/arch).
This is the exact error and then it drops to recovery:
Error after typing exit:
I have tried rootfstype too. No success.

I've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.

My Windows-system has broken down and I can't reach my files on the hard drive, because i'm unable to boot Windows.
I am running Linux from the cd, but when I try to open the hard drive, it gives me an error: 'Unable to mount the volume 'C:OS''
Details: '$LogFile indicates unclean shutdown (0,0). Failed to mount '/dev/sda1': Operation not supported Mount is denied because NTFS is marked to be in use.
Choose one action:
Choice 1: If you have Windows then disconnect the external devices by clicking on the 'Safely Remove Hardware' icon in the Windows taskbar then shutdown Windows cleanly.
Choice 2: If you don't have Windows then you can use the 'force' option for your own responsibility.
For example type on the command line: mount -t ntfs-3g /dev/sda1 /media/OS -oforce Or add the option to the relevant row in the /etc/fstab file: /dev/sda1/media/OS ntfs-3g defaults,force 0 0

I didn't have Linux until the day Windows crashed on me for the gazillionth time. I was simply playing some music in Windows Media Player as the entire PC froze. No CTRL+ALT+DEL, no alt F4... so I was forced to hard-reset my computer using the ON-button. After that it never launched Windows again simply because it didn't feel like it. Now, we're not here to find out why Windows is a bitch about all this, my real problem lays somewhere else. Seeing as a lot of important files were on my Windows drive I figured I could just install Linux on the other drive and fetch the files from there. The problem is I can't. Every time I attempt to open the disk I get the following error:
Quote:
Cannot mount volume.
Unable to mount the volume.
Hibernated non-system partition, refused to mount. Failed to mount '/dev/sda2': Operation not permitted. The NTFS partition is hibernated. resume and shutdown Windows properly, or mount the volume 'read-only' with the ro-option. Or mount the volume 'read-write' with the remove_hiberfile-option.
Code:
mount -t ntfs-3g /dev/sda2 /media/disk -o remove_hiberfile
I've tried both the ro-option and the remove_hiberfile but in both cases I'm given this error in the console:
Quote:
Mount is denied because NTFS is marked to be in use.
Choice 1: If you have Windows.. click on the 'Safely Remove Hardware' icon in Windows task bar to shutdown Windows cleanly..
Choice 2: If you do not have Windows then you can use the 'force' option...
And thus looping me back to the first command, upon entering I will again receive the first error. Things I have tried:
- said commands or slight variants
- re-installing windows (gets stuck during installation)
- used the Ultimate Boot CD in an attempt to access and copy the files from my Windows Drive onto an external hard drive / my Linux drive
- clicking the Drive icon furiously for a period of time in hope of a different result (which obviously did not work) Seeing as I can't screw open my laptop and take the drive out I'm really hoping there is some way for me to connect to the drive from Linux and extract the files.
- most likely my Windows system files have gone corrupt and I will need a format, but I'm not willing to do that unless I'm a 100% sure there is no way for me to extract the files first. I have an Acer ASPIRE 7720G (laptop) running an Intel Core Duo T7500 and have 2 physical hard drives (each as one large partition) of 500GB, further more it has 4GB DDR2 RAM memory and a fancy graphics card.

I was just playing some .flv files on my laptop with Ubuntu Lucid. At the start they played okay but after playing a few of those files the next files stopped playing. I tried playing one which had played just two minutes ago and it could not play. So evidently the problem was not with the files. Since I was using VLC I got an error message saying that the file could not be opened. So I restarted the laptop and tried playing them again and they did work(play). But the problem now is that the volume control which is placed at the top panel was not there anymore. I right clicked and selected Add to Panel. I searched for Volume Control but could not find it.

I am not well versed in using Ubuntu. I was using Win XP Pro SP3 on my old machine. I decided to make the move to Ubuntu. No problem since all files on the primary drive of the old machine were just OS related. I kept all of the important stuff (music, documents, reg codes, etc.) The computer had no problem importing the songs on the external drive to the music library. I am playing songs and loving it. Now the problem... when I am starting with ubuntu I don't find the drive and I can't mount it.
I get a box stating:
You are not privileged to mount this volume
DBus error org.freedesktop.DBus.Error.NoReply:

When I installed Ubuntu, I created an 52 gb encrypted partition which shows up in the disk utility, and in the window that opens when I click on the "home folder" icon. I get my normal windows partition, and under that the 52 GB LVM2 partition. But when I try to access it, I get this error.
Unable to mount 52 GB LVM2 Physical Volume - not a mountable file system
This is what fdisk -l shows

How can I fix this, and be able to access that 52gb partition? This is only my second day that I work with Ubuntu, so If more information is needed then let me know

I'm uncertain if this is the correct forum to ask this question. Please redirect me to the correct forum if necessary. I am attempting to install MS Windows 7 as a guest in VirtualBox inside Ubuntu Karmic Koala 9.10. on a ZaReason Strata 3660 with 4GB of RAM and adequate memory. The machine is correctly partitioned for this event. I am using the Ubuntu Walk Through as a guide: [URl].. All was going fine until VirtualBox asked for the .iso image from the MS cd 'UDF Volume'. There appears to be no .iso file in the UDF Volume.

I believe server section is the best when speaking of RAID stuff...
I have the following situation:We have a DELL T3400 with embedded fake raid on it. I dont know exactly how the system was setup (I wasnt here at that time), but the RAID was enabled in bios and while booting, the two harddrives would be seen as members of intel raid volume0 (RAID 1 mirror). I am not sure if the software raid was actually properly configured in Linux (Fedora 9) and if the OS was reconstructing the whole raid or it was just the bios part that was mirroring the /boot or just some parts of it. Frankly I find these hydrid raids very confusing.Some bad disk manipulation from my part caused the server to crash, but I was able to recover and boot just with one hard drive after using fsck.
I decided to get rid of the raid as it's not the right solution for the application we need it for and decided to go for a traditional single harddrive system and to use Ghost for Linux to clone to a spare disk when backups are needed.So I installed the latest Fedora 12 distribution onto another harddrive and disabled RAID in bios (changed from RAID ON to autodetect, which is the only other option).
Here is what I have now:
/dev/sda has the newly installed fedora 12
/dev/sdb is an empty harddrive that I would use as an intermediate
/dev/sdc is the old harddrive member of intel raid volume0
sdb was partitioned into sdb1 sdb2 and sdb3 and I created an ext3 filesystem on sdb2. The hard drive belonging to RAID volume0 (sdc) has a lot of work done on it and I would like to be able to recuperate the files to the new disk (sda). I cannot mount that old harddrive while in fedora 12, as it sees some unknown raid member filesystem on it probably assigned by the intel raid chip.
So I decided to do it from the other side: to boot from raid volume 0, and from there mount a third intermediate harddrive (sdb) onto which I would copy the documents and then mount the same harddrive from the newly installed fedora 12 and copy those documents from that intermediate harddrive.I can mount /dev/sdb2 from fedora 12 fine and copy stuff to and from it, but not when I boot from the RAID volume 0 harddrive (sdc) with fedora 9 on it. It keeps saying that the partition in question (/dev/sdb2) is an invalid block device.I am stuck here, as my knowledge in this sort of things is very limited.If somebody can indicate me how to recuperate files from that old raid harddrive onto the new fedora 12 drive, I would appreciate a lot.

I'm running squeeze (last updated today), and everything has been working great. There is only thing that would simplify my life minutely..Anybody know how can I have the volume buttons on my laptop change the "pcm" channel volume rather than "master"? If they could control pcm, then I could adjust the volume coming out of my headphones or my computer speaker (both controlled by pcm, but not master...seems strange to me) with just one click.I tried to find this info online, but all results seem to refer to an older version. The simple "click here, set this" solution no longer is possible.
