How to mount an LVM volume? (was lvm2 problem)

[Gene Poole]

I'm not 100% sure that this will work, however it shouldn't hurt either...

As root:

        mkdir /oldboot
        mount /dev/VolGroup00/LogVol01  /oldboot

The file systems should now be available off of /oldboot

If you want to make it available and mounted at boot time, update your 
fstab

Hope this helps...
