Segment with extent 19632 in PV /dev/hda2 not found

Hello!

When I restore the configuration with:

debian:/opt# vgcfgrestore computer100 -v -f /opt/neu2.vg

i retrieve the following errormessage:

File descriptor 3 left open
File descriptor 5 left open
File descriptor 7 left open
Incorrect metadata area header checksum
Segment with extent 19632 in PV /dev/hda2 not found Couldn't read all logical volumes for volume group computer100. Restore failed.

What does it mean? What can I do?

Best regards! Ralph
