[linux-lvm] Problems with LVM after updating from FC 3 to FC4.

Wed Jun 15 16:45:25 UTC 2005

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.
