I am not certain that's the same issue. I don't have more than one pv in
my lvm, and that is the raid 5 device. It checks out just fine when
tested, too...
# pvck /dev/md3
Found label on /dev/md3, sector 1, type=LVM2 001
Found text metadata area: offset=4096, size=192512
# vgck green
# echo $?

Details:
Setup:
Booting from /dev/sda1 and /dev/sdb1 in RAID 1, no LVM (no separate /boot).
LVM for storage, made from a RAID 5 on top of sdc, sdd, sde, sdf. The raid
is
the only PV in the LVM.
Depending on the versions of grub and os-prober installed, I get a
different
amount of errors when running update-grub, though it prints "done" at the
end
and exits with a status of 0 regardless.
Examples:
grub 1.98, os-prober 1.42 (Debian Stable)

no
