Re: [linux-lvm] Severe problem: data lost while adding a partition

["Heinz J . Mauelshagen" <mauelshagen@sistina.com>]

Sander,

can you tell what you mean with
'...something went horribly wron during install...' ?

Any particular messages which can help analyzing this ?

If you don't have any, take your most recent LVM metedata from the archive 
(/etc/lvconf/ ; you've got a backup, right ?), figure out disks used as PVs
with "vgcfgrestore -ll ..." and run "pvcreate -ff ..." and vgcfgrestore
on all of them. The archive you use shall _not_ include the recently added
disk.

Regards,
Heinz    -- The LVM Guy --
