[linux-lvm] Incorrect metadata area header checksum

[Eckhard Kosin <Eckhard.Kosin@online.de>]

Hi all,

I just reordered my disk space:  shrunk /dev/hda6, created a new
partition /dev/hda10 with this new space and added /dev/hda10 to the
existing volume group vg_uhu00.  After that I could boot and all seems
to be fine. but running vgscan I get

root@uhu:/home/ecki/backup/uhu# vgscan
  Reading all physical volumes.  This may take a while...

Some additional information:

I'm running Ubuntu 6.06 (dapper)

Partition table entries are not in disk order

The volume group vg_uhu00 uses the partitions /dev/hda8, /dev/hda9 and
/dev/hda10 and, I believe, but I'm not sure, /dev/hda5 (swap
partition).  I can't check, because lvdisplay gives the same output as vgscan above.

I have a line

  filter = [ "r|/dev/cdrom|", "r|/dev/hda[1,6,7]|" ]

in my /etc/lvm/lvm.conf

Any suggestions, how to get a clean volume group?

       Thanks a lot
