[linux-lvm] recover one LVM disk without the other

[linux-lvm] recover one LVM disk without the other

[burlen]

Hi recently we had a FC4 system with 2 disks go down do to disk failure. 
I replaced the bad drive, and installed Ubuntu 7 on the new drive with 
out the old drive. Unknown to us, FC4 was apparently using a LVM. I try 
to mount the remaining FC4 drive but get the mount error:

burlen@terra:~$ sudo mount /dev/sdb2 /mount_hd/
mount: unknown filesystem type 'LVM2_member'

How can I recover this drive? Really all I need to do is mount it and 
recover some data then we can repartion/ format it as well.

It should be a simple matter of using "vgscan" to activate the volume
groups. Of course this will only work if the volume groups do not
contain any physical volumes that were on the failed drives. If the vgs
do come up, use "lvdisplay" or "lvs" to display the logical volumes that
you can mount.
