[linux-lvm] Recovery of a damaged striped volume

[Heinz J . Mauelshagen]

Philipp,

presuming that just the first sectors have been wiped out, your option
is to run vgcfgrestore(8) on the wiped disk, the vgscan + "vgchange -ay".

See the vgcfgrestore(8) manual page for details, please.

Regards,
Heinz    -- The LVM Guy --
