A couple of months ago I setup an LVM2 device conisting
of a 400Gb SATA and a 80Gb PATA...
After a a couple of weeks, the SATA disk crashed (badly).
I managed to get it removed from the LVM2 setup, but now
I got the (warranty) replacement...
I've been trying to get the data on the PATA disk so that
I can recreate the whole thing, but I'm not shure how to
do that (I don't have much experience with LVM...
Now do I recreate the whole device with the two new 400Gb
SATA disks and move the data I already have on the PATA disk
to this new LVM2 disk/device?
I'm running PPC Ubuntu dapper, and this is (if it matters/helps)
what /etc/lvm/archive/* say:
----- s n i p -----
root@pegasos:/etc/lvm# grep ^description archive/*
archive/MovieShare_00000.vg:description = "Created *before* executing 'vgcreate MovieShare /dev/sda'"

I guess it's >= 4 that matters (seems like I didn't create it
correctly the 'first time' :).
This is what 'backup/MovieShare' contains (empty lines trimmed):
