I'm running CentOS 5.2, it uses LVM to manage the disks and we had a

came up it kernel panicked. Luckily it's not production, it was their
sandbox. But they didn't backup any of their files. I know the disks are
fine because I was able to boot from a linux live cd and mount the /boot
partition from the sda drive, and the sdb drive that has the mysql database
mounted at /var/lib/mysql and not using LVM. What I don't know how to do
is mount /dev/sda2 (root / partition) which is an LVM/ext3 partition. Does
anyone have the steps to mount this drive while booted into a linux live cd?
Commands that might be useful:
pvscan - verify the physical disks are present
vgscan - scans for volume groups
vgchange -a y - activates all volume groups
Now your logical volumes should be present and seen with 'lvscan' and
so can be mounted (/dev/VolGroup/LVName would be the volume to mount)
