Hi, I have one LVM volume of 3 hard disks. The box did have Fedora Core
3, I did upgrade it to Fedora Core 4.
Now I can’t mount my LVM.
I’m new to LVM, but here is what I have tried to do.
# /usr/sbin/lvmdiskscan -v
Wiping cache of LVM-capable devices
/dev/hda1 [ 101.94 MB]
/dev/hda2 [ 4.77 GB]
/dev/hda3 [ 1.17 GB]
/dev/hdd [ 57.27 GB] LVM physical volume
/dev/hdb1 [ 57.25 GB] LVM physical volume
0 disks
3 partitions
1 LVM physical volume whole disk
1 LVM physical volume
#/usr/sbin/vgchange -ay

Well, I don’t know what to do now? Have I lost all my data on the LVM
or? Or what is it with /dev/hdc ?
I have found one that might have the same problem.
