Getting comfused by LVM

[Perrin49]

I did a fresh install of FC6, but when I did it I didn't reformat my LVM partitions.

I'm now having trouble mounting that partition.

I think I can't see the forest for the trees, but I'm not sure what to do next.

Here is some info:
[root@MythBox MythTV]# /usr/sbin/lvdisplay

What do I need to do to be able to mount this partition?

[joshuapurcell]

Try to activate the volume group, then mount one of its logical volumes (in this case /dev/VolGroup01/LogVol00):
vgchange -a y VolGroup01
mkdir /mnt/oldLV
mount /dev/VolGroup01/LogVol00 /mnt/oldLV
Post if that gives errors. The best set of LVM instructions I've ever found is here:

Sweet.

Ya know, I have been on that page and it never clued in that I was missing the activate. I also didn't recognize that I needed to do the mkdir before I could mount (*slaps palm to forehead*)

Awesome - now to (re-)install MythTV
