CentOS 5 :: Volume Group "VolGroup00" Not Found

Sep 29, 2009

This is my development virtual machine, I had Centos 5.3 on it and a lot of stuff I really can't afford to lose.

First off I'd like to say if there is any method anyone knows of recovering information off a VMWare disk, I'd love to trash it. I've already tried the drive mapping in VMWare workstation but only the boot partition comes up and I need /home and /etc.

I was screwing around with the LVM size of the disk and totally screwed it up. I can see the two partitions on /dev/sda, /dev/sda1 as the small partition and /dev/sda2 as my large data partition (the one I need access to).

If anyone could guide me into getting my data off or rebuilding my LVM to get it booted again that'd be amazing.

Fedora Installation :: I2O Controller - No Volume Groups Found Volume Group "VolGroup00" Not Found Unable To Access Resume Device

Apr 8, 2009

Dual PII 400, 512Mb with a Promise SuperTrak 100 IDE Array Controller. At present I have only one drive on the controller, configured for 1 JBOD array. I install FC9 with no problem. New partition is created and formatted, Grub is installed, and then... Grub is found and booted, but then I get:

No volume groups found Volume group "VolGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01) mount: could not find filesystem '/dev/root' I can boot in rescue mode, chroot to the installed system. I changed the kernel boot parm "root=/dev/VolGroup00/LogVol00"

Fedora :: Volume Group "VolGroup00" Not Found - Froze Archive Drive

Nov 13, 2009

I have a dual boot system running FC8. I had a problem with an uninstaller on the Windows side that affected both the drives on the Windows and Linux sides. It froze my Linux archive drive. I removed the drive, and was able to boot the Windows side from a recovery disk, but not through Grub. I can't access Grub, but can start the Linux boot process with SuperGrub. The boot process gives the following errors:

No Volume groups found. Volume group "VolGroup00" not found. mount: could not find file system 'dev/root'.

Installation :: FC10 - Volume Group "VOLGroup00" Not Found - Unable To Access Resume Device

Feb 2, 2009

I already know "what" my problem is, however I am having difficulty fixing it. I recently upgraded our companies server to a HP ML150; decided to upgrade to FC10 hoping it would go smooth and it is not. It does not detect the SATA drives after the installation.

I get.

"Volume Group "VOLGroup00" not found
Unable to access resume device (/dev/VolGroup00/LogVol01
mount: error mounting /dev/root on /sysroot as ext3: No such file or directory

I know the problem is that my SATA is not enabled in the kernel or grub, but I don't know how to fix this. My internet searches are coming up a little short and LIVE discs are not working so I am having trouble figuring this out.

CentOS 5 :: Boot - Volume Group Not Found

Oct 5, 2010

Before creating this topic I googled a lot and found lots of forum topics and blog posts with similar problem. But that did not help me to fix it. So, I decided to describe it here. I have a virtual machine with CentOS 5.5 and it was working like a charm. But then I turned it off to make a backup copy of this virtual machine and after that it has a boot problem. If I just turn it on, it shows the following error message:

Activating logical volumes Volume group "VolGroup00" not found Trying to resume from /dev/VolGroup00/LogVol01 Unable to access resume device (/dev/VolGroup00/LogVol01) ... Kernel panic ...! During the reboot I can see 3 kernels and if I select the 2nd one the virtual machine starts fine, it founds the volume group etc. (But there is also a problem - it can not connect the network adapters.) So, it is not possible to boot it with the newest kernel (2.6.18-194.17.1.el5), but it is possible with an older one (2.6.18-194.11...)

I looked into GRUB's menu.lst and it seems to be fine. I also tried #mkinitrd /boot/initrd-2.6.18-92.el5.img 2.6.18-92.el5 no luck! Yes, I can insert DVD .iso and boot from it in "linux rescue" mode.

Red Hat :: RHEL AS4 Not Booting Up - Volume Group Not Found

Jan 18, 2010

I have run into some serious problems trying to start up RHEL AS4. I am trying to install Oracle on this box which by the way is running as a guest OS through VirtualBox. I was running with it fine yesterday. I was doing the prerequisites of updating the /etc/sysctl.conf file with additional kernel parameters. Prior to that I added another scsi virtual disk and extended a PV and left it at that for the night. I am since come back today and trying booting and am getting the following errors:

Volume group "VolGroup00" not found;
Couldn't find all physical volumes for volume group VolGroup00;
Couldn't find device with UUID "Some UUID of the device";
ERROR: /bin/lvm exited abnormally! (pid 318);
mount: error 6 mounting ext3;
mount: error 2 mounting none;
switchroot: mount failed: 22
umount /initrd/dev failed: Z
kernel panic - not syncing: Attempted to kill init!

I have tried running in rescue mode and it can find volume group VolGroup00. I also have installed Storage Foundation which includes veritas volume manager and other various veritas components. Does anyone have a clue what I am supposed to do here to get RHEL up and running again? I am running kernel version 2.6.9-42.EL if that helps as well.

Debian :: Volume Group Not Found After Kernel Upgrade

Aug 7, 2015

This is a problem about linux-kernel-3.16-0-4-amd64 and LVM, I guess. I decided to write this here in case other users who installed their debian system with encryption enabled experience this problem with a recent kernel upgrade.

I use debian jessie. Today I gave the command:

Code: Select allapt-get upgrade

There was a linux-kernel upgrade to 3.16-0-4-amd64 among other packages to be upgraded.

After this upgrade my computer cannot boot anymore.

I get following error:

Code: Select allVolume group "ert-debian-vg" not found.
Skipping volume group "ert-debian-vg"
Unable to find LVM "volume ert-debian-vg/root"
Volume group "ert-debian-vg" not found
Skipping volume group "ert-debian-vg"
Unable to find LVM "volume ert-debian-vg/swap_1"
Please unlock disk sd3_crypt:

And it does not accept my password.

I used rescue environment on debian jessie netinst iso and decrypted the partition and took a backup of my /home. Now I have not much to lose if I reinstall my system but I still want to fix this problem if possible.

I have reinstalled the kernel using debian jessie netinst rescue iso but nothing changed.

I have Timeshift snapshots located at /home/Timeshift but timeshift --rescue command cannot find a backup device, it sees the device as crypted. If I could restore a snapshot it would be very easy to go back in time and get rid of this problem. It would not be a real solution, however.

There is not any old kernel option in GRUB menu. So removing the latest one does not seem as an option.

Red Hat / Fedora :: Extending Root Partition - Volume Group Not Found

I am trying to extend my / size as its full. Well the volume group is VolGroup00 & logical volume is LogVol00 but when. I run the command vgextend VolGroup00 /dev/sda8. It says volume group not found. Can it be because I have WindowsXP in my /dev/sda1, which falls under same Volgroup??

CentOS 5 :: Remove A Volume Group / Array?

Nov 16, 2010

I'm trying to do a disk upgrade on some servers. They are using LVM with DRBD on top and each LVM volume contains a Xen image. I have already created identical volumes on another volume group, copied the data and pointed DRBD to the new source (Which seems to have worked).

What I am unsure of is how to safely remove the disks. The disks are an Areca Raid 1 array and support hotswap. Can I just pull them out of the machine or is some sort of command needed to tell LVM or the kernel to disconnect from the physical array device? Is removing the raid array from the Areca management GUI first a good idea?

General :: VolGroup00 Not Found After Moving To 3ware 9650SE

Mar 5, 2010

I wanted to take a current system with a working CentOS 4.7 LVM and move it to a 3ware 9650SE raid card so that I can mirror the drive and have a RAID1. The current system has 2 hard drives. One hard drive contains the CentOS 4.7 LVM install and the second drive is not part of the LVM. The second drive is being used for basic backups. I took a copy of the OS HD using dd and confirmed it worked by booting it up with the hard drive on the motherboard. When I connect it to the 3ware raid card with a new hard drive for the RAID1 and configure the 3ware raid card for RAID1, I get the "Volume Group "VolGroup00" not found" error. It gets past grub and then starts to load up but that is when the error occurs.

The error message exactly is:
Making device-mapper control node
Scanning logical volumes
Reading all physical volumes. This may take a while...
No volume groups found
Activating logical volumes
Volume group "VolGroup00" not found
ERROR: /bin/lvm exited abnormally! (pid 461)

Fedora :: Dumb Lvm - Volume Group And Volume Names Are Gone From View

Jan 22, 2011

I don't know much about lvm and I've managed to screw up a drive. I had a 500GB drive with FC14 on it and I wanted to copy over a load of data to my new 1TB that was replacing it. I set up my new install the same way as the old...including the same volume names (error number 1 I think) I successfully mounted the old/500GB drive (using vgscan and vgchange -a y etc.) using a laptop (running FC13) and an external hdd cradle. I could access the files I wanted but this wasn't the machine I wanted to copy them to (I was doing this while waiting for the install to finish on the new drive).

When I tried the same process on the new install I found that having two lvm with the same name meant I couldn't mount the external one. So I opened the disk utility (palimsest) and was going to change the name of the old volume group but it wouldn't let me do that. I then thought maybe I could get away with just changing the name of the partition where the files were and maybe I could add it to the mounted group or something so I changed it to lv_home2. This changed the name of my new/1TB lv_home to lv_home2 as well. So thinking that wasn't the answer I just changed the name of the new lv_home2 back to lv_home.

From that point on I haven't been able to see the old drives partitions (the new volume group still works so far). I has a physical volume but the volume group and volume names are gone from view. When I try to vgscan on my main computer or the laptop I had it working on earlier I get:

General :: Move / Copy A Logical Volume From One Volume Group To Another?

I'm rearranging a bunch of disks on my server at home and I find myself in the position of wanting to move a bunch of LVM logical volumes to another volume group. Is there a simple way to do this? I saw mention of a cplv command but this seems to be either old or not something that was ever available for linux.

CentOS 5 :: File Based Locking Initialization Failed - No Volume Groups Found

I'm working on a kickstart install to automate a lot of monotony doing installs. When i use the kickstart install i get an error on boot saying "File based locking initialization failed" "no volume groups found". Then it proceeds to boot up with no issues and appears to work just fine. Below is the section of my ks.cfg for creating the partitions: %include /tmp/partition.cfg is included where the partition info usually occurs. The user is prompted in the pre script for how large they would like the partitions to be and then the script below creates the included file with partition info

CentOS 5 :: CentOS5 With Clustered Lvm2 : Not Booting Anymore (VolGroup00 Not Activated)?

Sep 13, 2010

I "inherited" a cluster of 2 systems with XenCluster, based on CentOS 5.5. About five weeks ago I ran the (long overdue) yum update, which crashed in the middle of updating on both nodes, so I had to reinstall all those packages by hand and had to re-enable their startup. So both systems are already in the not-ideal state.

One system rebooted itself during my absence and now won't boot anymore. It seems to boil down to clustered lvm not being activated in the initrd and therefore no VolGroup00 available, which contains the root. The other volume group has good reasons to be clustered but the root does not need to be. But I can't fix it from a rescue CD, every time the error comes up that the volume group is clustered.The exact error display at boot is at

http://people.cs.uu.nl/koos/screen-20100913140414.png

what do I do to either fix the startup to ignore VolGroup00 being clustered OR change the status of VolGroup00 to non-clustered?I notice the other system has this too so my best guess is that I'll have the same problem in a bigger way when this system reboots too. Hoping for no power failures...Relevant versions of stuff:

centos 5.5
kernel 2.6.18-194.11.1.el5xen
mkinitrd-5.1.19.6-61.el5_5.2
lvm2-2.02.56-8.el5_5.6
lvm2-cluster-2.02.56-7.el5_5.4

Fedora :: How To Reduce A Volume Group

Mar 17, 2011

I have one HD and a VG spanning it's entirety. I resized a LV and freed up 10GB within the VG, but I want the 10GB outside the boundary of the VG so I can install another OS for testing purposes. For some reason I'm not able to do this. I don't know if I understand LVMs correctly. Maybe there can be only one VG on a HD?

Fedora :: Extend Volume Group Using LVM?

Debian :: Encrypt A Volume Group - By Using RAID Under

Jul 10, 2010

After months of using Lenny & Lucid Lynx without issues, I come back to the good existential questions.

I'd like a completely encrypted disk (/ and swap) in addition to the Xp partitions (not that safe but I'll switch completely to Linux once I have solved everything.

1. I create an ext4 partition for /boot
2. One other (/dev/sda7) that I set for encryption,
3. On top of that, I create a PV for lvm2,
4. I add to a VG,
5. I create / & swap in the VG.

However, if I add a hard drive, I will have to encrypt the main partition, add it to the VG & then expand /. So I'll need 2 passwords at boot time to decrypt.

So I'd like to:

-Encrypt the VG directly, it would solve everything but no device file appears for the VG, only the PV and th LV.

-After hours of search, I couldn't find a solution for a single password...

Maybe a hope with a filesystem like btrfs in the future providing encryption, but I'll still have to create a swap partition out of it (or create a file for swap but no hibernation possible).

General :: LVM - Multiple Installations In One Volume Group?

I am not familiar with LVM at all, although I have successfully got it up and running in Slackware. What I would like to know is, could I create one Volume Group in a Physical Volume consisting at the moment of just one disk, and install separate Linux releases into Logical Volumes in this solitary VG? So, for example:

/dev/sda1 = Physical Volume
volgroup = Volume Group
lv01-root = Slackware root

Server :: Raid6 - How To Extend Volume Group

May 16, 2010

I'm running debian and used mdadm to setup up a raid 6 array with 4x1TB drives with roughly 1.86TB's available with lvm. Then I added 4x1TB drives to the array. So now I have an 8 drive raid 6 array with 5.+TB's available, the array sees all available space. The question is how do I extend the volume group so that it uses the whole raid and not just half of it. As of right now the volume group is only 1.86TB's.

Fedora :: Creating Volume Group To Add New Hard Drive?

Oct 16, 2009

This concerns the Logical Volume Manager (LVM).

1) Why would I create a new volume group to add a new hard drive to a system, rather than add the drive to an existing volume group?

2) If I created a new volume group and added a new hard drive to it, would I see the total free space (I see 30 GB now via the file browser)? For example, if I have 30 GB free on the main drive (with the OS), and I add a new drive of say 40 GB in a new volume group (using LVM) would I see 70 GB of free space? That doesn't seem to happen.

General :: LVM - Adding New Disk Space To Volume Group?

I plan to install a server using LVM. I thought a partition schema where /boot would be in an ext4 partition while / /usr /var /home and /opt would be in the LVM. My question is: if I'm putting / into the LVM, is it necessary to divide /usr /var /home and /opt into different logical volumes? If I divide them, would it become harder to maintain when new disk space has to be added to the volume group?

Fedora Installation :: F11 - Kickstart Setup For Mirrored Volume Group

Oct 22, 2009

Fedora 11. I am trying to setup kickstart so it lays out a mirrored volume group. I have 2 disks sda and sdb. I want a primary partition on each disk 200mb in size for /boot. This is to be mirrored onto raid device md0 (raid 1). The rest of each disk is to be setup partition which grows to use the remaining space, and is also mirrored (raid 1) md1. Onto md1, I want an LVM volume group called rootvg, and logical volumes set up on there for /, /home, /usr, /tmp etc. I can lay this out manually, and it works fine. However, the code below, which is slightly amended from a previous anaconda-ks.cfg file doesn't work.

Code:
clearpart --linux --drives=sda,sdb --initlabel
part raid.11 --asprimary --size=200 --ondisk=sda
part raid.12 --grow --size=1 --ondisk=sda
part raid.21 --asprimary --size=200 --ondisk=sdb

raid /boot --fstype=ext3 --level=RAID1 --device=md0 raid.11 raid.21

Fedora Hardware :: Resize A Logical Volume Group Partition?

May 17, 2010

Ok so I have one drive. /boot /lv_root and /lv_swap

At the end of the drive I have 32 gigs of free space still contained in the logical volume group. I want to remove it from the LVG but this is on one device. Supposedly there is a way to do this, pvresize and fdisk.

That's normal. pvresize "just" updates the PV header and VG metadata.

#So I guess the partition table has to be modified somehow?

Yes. That was mentioned in my reply: "Then shrink the partition in the partition table."

You can use fdisk or any other partition table editor for this. Some don't support resizing a partition. In that case, you can delete and create a smaller one. If doing the delete/create dance, you *must* create the new partition on the same cylinder boundary as the current one to preserve the current data.

Ive read from every source on LVM its not possible to do this. Why on earth would any Linux developer put LVM on a single drive system by default? Were they even paying attention? I dont mean to go off on a rant but if there are multiple drives LVM makes sense. However if you only have one large drive LVM holds your system hostage and you have to crawl thru the pit of hell to get it back.

I understand you have a choice in the matter when you install Fedora but its really the worst possible choice for default. Many newcomers to Linux run into this problem with LVM. If you cannot resize LVG's the software should have never been put into a Linux distro in the first place.
