[linux-lvm] pv problem?

[Heinz J . Mauelshagen]

Tom,

you seem to have hit the gcc 2.96 or similar optimizer bug.

Please regenerate the LVM software *without* optimization (change "-O2"
to "-O0" in the configure script;run "make distclean";
run "./configure;make;make install").

With regard to PVs displayed as "NOT available": they simply belong
to a not activated volume group and hence have that status.

Regards,
Heinz    -- The LVM Guy --
