[CentOS] Was, Re: megaraid/PERC, is LVM

*sigh*

After all that, I found one of our R905's is basically not in use at the
moment, so, fine, I umounted a couple of data drives, pulled them, and
plunked what I *thought* was a RAID.

And saw partitions, this time - dunno why I didn't see them on the other
box. fdisk... and the damn things are LVM.

So, I've done pgscan, vgscan, see the group name, tried vgchange --mknod,
but the groups aren't active, nor is there a VolGroup directory created
down in /dev. Anyone know what I've missed?
