[linux-lvm] vg fun!

[Heinz J . Mauelshagen]

Daryl,

could well be an array dereference bug fixed in the recent version.
Please try the attached statically linked vgscan version 1.0.6 (presuming i386;
not send to the list).
If that works, you want to upgrade to 1.0.6.

Regards,
Heinz    -- The LVM Guy --
