Re: [bug #37569] unknown LVM metadata header

[Øyvind Hvidsten]

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 $?
0
