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)

Why could there not be a 3-way or even 4-way RAID level 1 (mirror)? It seems every hardware (and at least the software I tested a few years ago) RAID controller only supports a 2-way mirror.I recently tried to configure a 3ware 9650SE RAID controller. I selected all 3 drives. Then RAID 1 was not presented as an option. Only RAID 0 (striping, no redundancy) and RAID 5 (one level of redundancy, low performance). Is there some engineer who thinks "triple redundancy is a waste, so I'm not going to let them do that"? Or is it a manager?
Mirror RAID should be simple, even when more than 2 drives are used. The data is simply written in parallel to all the drives in the mirror set, and read from one of the drives (with load balancing over parallel and/or read-ahead operations to improve performance, though some of this is in question, too).

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:
Reading all physical volumes. This may take a while... 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"

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'.

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.

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.

I am using Centos 5.2, with the latest 3ware driver installed. The 3ware bios shows all the external disks (its a 9690SA-8-E), they are setup as Jbod, but when I login to Centos I do not see my attached drives only my local ones. When using fdisk -l under root I see my attached disks but not my external array:
[root@sf ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md1 7.6G 749M 6.5G 11% /
/dev/md2 190M 24M 157M 14% /boot
/dev/mapper/vg01-scratch

I'm helping my brother setup a server he has. The server has a 3Ware 9690SA Hardware RAID card, and it has 4 x 2Tb 5400 RPM Samsung Harddrives. When I boot into the 3Ware BIOS, it recognizes all 4 drives, no problem. What he wants to do is install them in RAID 10 for a 4 Tb mirrored volume for performance and redundancy. When I try to create a RAID array with the 4 drives, and set it to use RAID 10, it only allows me to utilize 2079 Gb (1/4 x 8 Tb), which is half of what I would expect for this RAID config.
Assuming I go ahead and allow it to build the array with this volume, we can go on to install Fedora 14 with no issue, but still only 2 Tb are available. This is our first time setting up a RAID array like this, I've also tried enabling Auto-carving to insure that I have support for physical volumes larger than 2 Tb, but to no avail. With the version of Linux we're running, and the RAID card he's got, it should support greater than 2 Tb PVs either way though.

I have several servers running 3ware 9750 raid controller cards. The 9750 does not have a driver built into the linux kernel and must be manually added during installation. This hasn't been a problem as I had a driver compiled for the kernel versions I was using.
There isn't a driver available precompiled for 10.04.3. I would like to compile one from the source code I downloaded from the manufacturer, but I am not sure where to start. I've looked for some sort of walkthrough or directions, but I haven't had any luck. I've compiled and installed software from source, but I have a feeling that drivers are probably a bit more complicated, especially since I will need to compile the driver on a system that does not have the same kernel version.

I Made a fresh Installation of Fedora 13. It shows VolGroup00 and File System in the Computer on desktop.
The size of the hardisk is 160gb. The file system shows some 4gb. I'm not able to open the Volgroup00. On double clicking it it shoes the error "Unable to mount location"
on entering fdisk -l,
It says the partiton one /dev/sda1 did not end on cylinder boundary.
The partition /dev/sda1 ends on Cylinder 63 and the emaing LVM partition also starts on Cylinder 63.
I tried reinstallling after dropping both the partiotions 4 times, but this is always the case.

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
(from the still running system)

I like the buttons on the left. I'm running 10.04 & I know how to move them. The problem is that changing themes will move them back right. OK, if the new theme has them on the right that's OK. But going back to the other theme doesn't change them back. They don't seem to be controlled by the theme, or I'm just not doing it right.

I have limited experience in terminal, but let me first explain what I am trying to do to see if there is some easier way to do it. Basically I want to change the skin in aMSN. I downloaded the new skin but am unable to unzip or move it without /root permissions. I don't know how to acquire this without being in terminal. So I figured there had to be some way to go into the terminal and use it to move the unzipped folder from the desktop to the aMSN skins folder.

I'm told to go to /home/jbander/Downloads, so how do I do that, I assume you do it in terminal but what do you do next, I can get to home but thats it. How do I go from one directory or file or whatever they are, to another and once I'm there what do I do to see what is in the download file. One more question if I want to change it from e.g. cow to e.g. duck how would I do that(they are just arbitrary names) how do I get rid of cow and how do I put duck in it's place.

We are really scratching our heads on this one.We moved 3 Dell PowerEdge servers with Fedora 12 x86_64 from one datacenter to another.2 of them are fine but the 3rd we cannot log into any more.The KDE login screen comes up,e user names are shown, but our passwords don't work.Going to the console, we cannot log in as root with the password either.Also, I set up shared keys for ssh between the 3 boxes so that I could ssh between machines without entering my password -- that doesn't work either. This one is one of the head scratchers since /home is on a different disk.I'm 1,600 miles away and the tech that went into the cage to try from the console does not know Linux. Dunno how he got picked...
What exactly would have been corrupted to cause this behavior -- unable to login locally AND ssh authorized_keys no longer works?Oh, and apparently they were initially able to get into the machine from the console after the move since they were able to configure the NICs. But now we can't.We know how we can get a root login on a reboot from GRUB, but we don't know what to look for as far as what might be wrong with the system once we're in

I dual boot XP and Linux. Right now i've been running Mandriva but haven't been that satisfied with it as of late and am thinking of switching to the new Ubuntu. My question is, what would be the best way to go about this.. would i want to switch back to the windows bootloader, remove the linux partitions and then remake these partitions from free space during the Ubuntu install?
My main concern is wether it is necessary to switch back to the windows bootloader before proceeding (LILO currently) as i have no problem removing the old Mandriva partitions... I thought I'd reply to this thread rather than start a new one:
Doing almost the same thing with Mandriva, Vista & Grub going to Suse.
Am I to assume that I shouldn't have issues and that the Suse bootloader will overwrite Mandrivas? It is written in the MBR.
Now that I saw the poll of top distros for new users, I'm considering Ubuntu & Mint as well.
Will any distro's bootloader overwrite a prior version?

I am an experienced Windows Server user/admin (over 12 years). I have touched Linux here and there and know my way around the "GUI" portion of it; which is not to say much.
In Windows I am not just a GUI guy and have been using script and command line since the DOS days.
I want to learn Linux Server internals just as I do in Windows Server. Most of the books/guides I find are geared toward moving windows desktop user to Linux. Most linux books that I have come across are not for porting your knowledge from Windows servers to linux but instead they start to teach you linux from abc and then I lose interest because I know the basics.
what I should start so that I can pick the right distro for a server, configure it to be a solid server and deploy/manage it appropriately? I plan to use this knowledge at customer sites instead of just at home.

Lets say I have /dev/VolGroup00/LogVol00 which is a 5.8 GB ext3 partition that resides on a 10GB drive. This is just a logical volume partition, one of a few... this being the one that isn't swap, the main data.
I have a 20GB drive... I want to move the LogVol00 to it, and it is /dev/sdb. I partition /dev/sdb1 to be 8192 MiB in size in gParted.
I move as such:
dd if=/dev/VolGroup00/LogVol00 of=/dev/sdb1
The operation finishes with no problems.
Fsck reports clean... so... I run:
fsck -l /dev/sdb1
A few small errors pop up and they get fixed.
My free space remaining, as expected, is 5.8 GB.
I go into gParted and resize the partition to 15GB in size, still working on the 20GB drive.
It does so, the operation completes.
I have what I want: the partition was taken out of LVM, data was retained, I have no issues resizing it. Additionally I tried writing random junk to this new filesystem to test to see if it's broken, and also deleted 3gb of files already on it with no problems.
I just want someone to look this over and tell me if they see any problems with what I've done. I've tested this twice so far with success each time. Is there a better or easier way to do this? I do not want to keep LVM for various reasons. By the way, you might be wondering why I made the partition 8GB for an almost 6GB system. Because the first time I did it, I put down a number that was too exact and it didn't work. Overestimating to 2GB fixed the issue - I'm guessing this is probably due to block size.

I am pure fresher in cvs, svn, git administration. we bought new server and now I want to move above repositories from old servers to new server. Becuase old servers are not having enough free disk space & having very lower configuraion. So how to move cvs, git, svn repositories from old servers to new server. But these repositories also should be in old servers becuase once when developers confirm that everything is working fine then we will completely replace the old servers with new.

I'm trying to move files from one directory to another. I only want the files that start with a capital and within a certain range. Say all files that start with a capital between A-K. I've googled this and they all say to use: [A-M]*. But it moves all files A-M regardless if they are uppercase or lowercase.

I run a dell inspiron 1521 laptop, and 2 weeks ago i went from Vista to Ubuntu. What i shoulda done was splitting my hard drive and having them both on my pc. What i ended up doing was taking the whole disc space simply because i absolutly hate windows and loved the general idea of linux where software should b accessible to everyone and free of charge.
Unfortunatly, its been a major headache ever since, spent a week trying to set up my wireless and graph card, and now, 2 weeks into it, my biggest addiction, world of warcraft, is really starting to itch. ive tried to follow guides, im getting errors allong the way, and for now, just dont feel like going through another troubleshooting war with my pc.
My general plan is, getting Vista back, and then installing Ubuntu because i still love it, and use linux for the rest of my general activity.
when i launch the recovery disc, i cant select a hard drive to install it to.

I have a local drive on this machine which I want to use, but I cannot figure out how to move the location of the trash can. I am using redhat with nautilus.

I have 2 harddisks, and a very new SuSE 10 installation.
Suppose I have a user called test in the users group. At present its home directory is /home/test. This is on one of the harddisks, sda.
Now I have a partition on the other harddisk /other. I would like all my users to be on sdb, so that their home directories are /other/users/test for instance for the test user.
I have played around with YaST to create another user "toets" in /other/gebruikers, but I would like to have it as /other/users/toets.
I want all the user accounts on /other.
