I'm trying to recover from a hard disk crash on a Fedora 5 system. The hard drive with the OS installation failed, but the two other drives in the system (data only) are fine. I had originally installed both of these "data" drives in their own volume group, separate from the VG for the main drive with the Fedora installation.

Anyway, here is the problem. I've replaced the main drive, installed Fedora 5 again, and now I'm trying to get LVM to properly recognize and mount these two additional drives. LVM can find the physical drives, and it can identify the VG to which they belong, but it doesn't show any logical volumes on either drive (or even a filesystem), and I cannot mount them.

Any ideas?

Thanks.

have you tried a live 'rescue' CD ?

knoppix or systemrescueCD - i've used both in the past with some success

copy the data (if u can see it!) onto an external drive and start again

neill

What steps have you tried to access the vg?

have you tried vgscan && vgchange -ay ??
the last command should activate available volumes as /dev/<vg>/<lv>

Thanks a million - that was the command I needed!
