Dear Heinz, Thanks a lot for your quick response! I've not seen the problem for a week since I added a "sync()" right after every operation, including "vgcreate", "vgextend", "lvcreate"...... Is this the answer to my VGDA problem? I don't know. But it's just gone!! I'll keep the script you gave me if the problem should come up again. (Hopefully not!!) Thanks again!
