Subject: [gentoo-user] rescuing lvm data
Date: Wed, 24 Oct 2012 22:08:52 +0200 [thread overview]
Message-ID: <50884AD4.4060806@xunil.at> (raw)
greetings ...
the server in my basement is driving me nuts ... and I start making
mistakes ... sigh
It had a LVM volume group ... consisting of two PVs ...
The question in short:
if I only have one PV at hand, which contains all the PEs of a given LV
... (how) am I able to extract/export/read the contents of that LV?
background:
when I searched for the reason of those crashes, I removed and swapped
and cloned hard disks all around.
Right now I am on a brand new machine and want to sort out harddisks etc.
One PV wasn't detected correctly ("unknown device") even though it had
the correct uuid. I did some "pvcreate -u" on it ... and now those LVs
on it aren't accessible anymore (can't mount or even fsck).
My luck (I hope!): I have a clone of that harddrive.
But I don't want to simply plug it in because I fear to ruin things as I
already messed up that VG further by trying stuff like vgcfgrestore etc.
Yes, my fault.
The clone contains all the blocks for an LV I would like to keep
somehow. So I assume it should be possible to access them?
(explanation why there is no backup: the data is mythtv-stuff, video
which is nice to have, but not critical.)
Thanks, Stefan
