[linux-lvm] using a read-only PV

[Eduard Bloch]

Hello,

is it possible to use a physical volume in read-only mode? The idea is:
put a snapshot of the PV on a CDROM. Later, build a volume group, with
this read-only volume as the first volume in the snapshot mode, and an
additional volume on the harddisk where the differences are stored.

Is a such scenario possible - or already useable?

Gruss/Regards,
Eduard.
