This is the linux LVM group, but I can assure you that LVM in AIX 4.3
is *very* stable. You'll have to ask in an AIX group, but I suspect that
it is still very good. As far as I'm concerned, AIX LVM is the one to
beat for open source LVM.

AIX 4.3 LVM didn't support snapshot, but mirroring (and striping) worked great,
(and are still working great).
Linux LVM got snapshots before mirroring/striping. This was sensible because
mirroring/striping is available via the linux 'md' driver - albeit somewhat
kludgy compared to LE based LVM support.
