[linux-lvm] Incorrect metadata area header checksum

["C'est Pierre" <cestpierre gmail com>]

Hello,

I am running through this error in CentOS 4.3, has anyone gone through
this situation?

I added a disk to the VG, initialized it with pvcreate and vgextended
our VG. However, it's constantly showing these messages:

# vgdisplay
 Incorrect metadata area header checksum
 /var/lock/lvm/V_VG00: open failed: No space left on device
 Can't lock VG00: skipping

which don't seem to be true at all:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VG00-LogVol00
                     9.0G  7.0G  1.6G  83% /
/dev/sda1              99M  9.0M   85M  10% /boot
/dev/mapper/VG00-LogVol01
                      14G  510M   13G   4% /opt/lampp/var
/dev/mapper/VG00-LogVol02
                     977M   18M  910M   2% /tmp


Not of the disks is fully used, yet I can't even write to /root

# >foobar
-bash: foobar: No space left on device

Any idea?

Thanks
Pierre
