Hmm - still another problem. That's how far I got:

# df -h

I moved everthing from /dev/hdb1, all PE are free now. But trying to
reduce the VG gives me an error:

# vgreduce /dev/VolGroup00 /dev/hdb1
  /var/lock/lvm/V_/dev/VolGroup00: open failed: Datei oder Verzeichnis
nicht gefunden
  Can't get lock for /dev/VolGroup00


This means that some file or directory is not found. Any ideas what's
going wrong here?
