[linux-lvm] pvmove: ERROR "pv_read(): device major number"

[Heinz J . Mauelshagen]

Stephan,

you seem to run LVM 1.1-rc1 as pvmove states which
had a flaw checking used devices.

Could you please either use LVM 1.1-rc2 or LVM 1.1 from top of CVS
(see instructions at www.sistina.com IRT CVS repository on how to check
that out) and tell me, if that works.

Please keep in mind that LVM 1.1 is unstable development software not meant
for production systems!
