[linux-lvm] Incorrect metadata area header checksum



hi-

what does this error mean, and how do i rectify it? i have existing lvm
volumes on this box, but creating this big one (~350gb) on my new
software-raid5 array is giving me grief. i can mke2fs /dev/md2 just
fine, but when i try to install lvm2..:

root cerulean:~# pvscan
  PV /dev/md1   VG raid1   lvm1 [15.65 GB / 0    free]
  Total: 1 [0   ] / in use: 1 [0   ] / in no VG: 0 [0   ]

root cerulean:~# pvcreate /dev/md2
  Failed to read label on physical volume /dev/md2
  Physical volume "/dev/md2" successfully created

root cerulean:~# vgcreate raid5 /dev/md2
  Incorrect metadata area header checksum
  Incorrect metadata area header checksum
  Volume group "raid5" successfully created

root cerulean:~# vgdisplay raid5
  Incorrect metadata area header checksum
  Incorrect metadata area header checksum
  Volume group "raid5" doesn't exist
