I had a machine running Fedora Core 3 that had a severe motherboard failure during an update session.
I cannot get the drive to boot properly in another system so what I was hoping to do is add the drive to this second system as hdb and just pull the data that I need off of the drive.
How do I go about getting the data from the original LVM volume onto another system? I am new to working with LVM and I do not want to screw up my data.
you can mount it like any other file system.. the fact that it happened during an upgrade sounds like too much of a coincidence to me though. Just plug in the hard drive and mount it. Are you sure the motherboard is dead?
I definitely verified the board is bad, the IDE controller ports do not work and the mouse PS2 port does not work either.
As for pulling the data off, are you saying that I can mount the partition (/dev/hdb2) just like a normal partition? I was concerned just directly mounting it because it was part on a LVM volume. I will give a shot and see if I can pull off the data.
If the distribution you are using is not natively LVM aware (e.g., FC4 Linux Rescue mode is NOT natively LVM aware), try activating the volume group(s) by running:
lvm vgchange -a y
OR
vgchange -a y # Note: this is a symlink that may not work
Then run:
lvm lvscan
OR
lvscan
to see the logical volumes.
Then mount them like any olde partition:
mount /dev/VolGoup00/LogVol00 /mnt/temp
or something like that, where /mnt/temp or whatever you want to mount under preexists.
I'm having the very same problem, now my system won't boot, and displays the same message about not being able to find the PV with the specified UUID.
I'm going mad! I can't access my data, and I need it badly. I've asked in several forums, and nobody has an answer. I would be happy if I could hex edit my partiton, and try to recover the info myself, is it possible?
I have not found a good way to resolve this issue. I have worked with a few tools, (insert, recovery, and dfsee). The issue I have run into is that LVM is not really supported in recovery tools. You can do some things but not an extreem amount.
I am still working on my issue and if I find something that works I'll post it here.
I tried something with Partition Magic, from my Windows XP, but unfortunately it prevented me from booting windows. Now that i've corrected it, I'm thinking of deleting my NTFS partition, and installing another Fedora Core 4, to see if it's easier to recover from there. What do you think?
dfsee doesn't support Linux version of LVM. The other tools do.
If you do an install you jeopardize your data. You should go buy a new disc and do a drive to drive copy with one of the tools. Then you can work on the disc you are having trouble with.
Your best bet is to use a bootable hard drive recovery tool. Insert and Recovery tools are ones you should be able to find at sourceforge.net.
So, don't do anything to your disc before backing it up.
