[linux-lvm] LVM and HD-crash

[Heinz J . Mauelshagen]

Markus,

you need to replace the failed drive, set up the same partition table
you had on the gone one and vgcfgrestore(8) LVMs metadata to it.
See the manual page of vgcfgrestore for details.
vgscan + "vgchange -ay" should then bring your VG back to life.

Getting data back makes only sense, if you've got LVs, which *don't* have any
extents allocated on the gone drive. Otherwise your filesystem
stored in there will complain loudly cause of missing data and metadata.

If you need more redundancy, please think of soft/hard RAID.

Regards,
Heinz    -- The LVM Guy --
