I used the following to figure it out.
http://tldp.org/HOWTO/LVM-HOWTO/
You'll probably need to do /sbin/vgscan to figure out the lvm name then
run
/sbin/vgchange -a y;
mount /dev/VolGroup00/LogVol00 /mnt/whatever
can't remember how I arrived at VolGroup00/LogVol00 but think there is
an explanation in the how-to
to automount I do in fstab
/dev/VolGroup00/LogVol00 /mnt/whatever ext3 defaults 1 2
[note: I had run the vgchange prior to that once though, changed fstab
and it comes up automounted now without doing vgchange.
Hope that is what you were asking.
