The disks are back in their original machine currently. 

pvdata gives me:

--- List of logical volumes ---

pvdata -- logical volume "/dev/vg01/usr" at offset   1

"VG Name" in "--- Volume group ---" is empty. Is this normal? In case
this or some other errors within the data structures within one or
more partitions is the cause of my problems: 
My setup is currently working obviosly. Is there a way to write this
working configuration into every LVM partition's metadata overwriting 
some possible errors there?
