If you ever run in to a scenario where you have a VM which won’t boot. You will need to use an install disc to get into rescue mode.


Boot your rescue media.
Scan for volume groups:

# lvm vgscan -v

Activate all volume groups:

# lvm vgchange -a y

List logical volumes:

# lvm lvs –all

With this information, and the volumes activated, you may be able to mount using:

# mount /dev/volumegroup/logicalvolume /mountpoint

If you get an error along the lines of:
you must specify filesystem type

You will need to run a file system check on the logical volume first.

# fsck -f -y /dev/VolGroup00/LogVol00

Then try mounting again. Good luck.
