Greetings,
I am having problems with my LVM setup. I recently had to reboot my
machine and when it came back my, my LVM is not mounting. It is currently
only a one-drive setup (was going to add more drives to LVM eventually).
Any help would be greatly appreciated. Most of this data is backed up,
however there are a significant number of photos that can't be replaced from
a recent event. If anyone could point me in the right direction for
something to try that I've missed, it would be greatly appreciated.
pvscan, lvscan, vgscan, and lvmdiskscan all report nothing useable.
I have a current backup in /etc/lvm/backup/media_vg
# vgcfgrestore -vv media_vg
Setting global/locking_type to 1
Setting global/locking_dir to /var/lock/lvm
File-based locking enabled.

(Is that a proper Id? Plus, looking at my media_vg backup, I don't believe
there should be a partition because the hint is /dev/hdb, not /dev/hdb1)
