Nope, the drives are jumpered master (without slave). I'm puzzled, because everything else works without any problems. dump(8) with snapshots seems to be an excellent torture test. > Once I fixed the jumpering and swapped in > a better hard disk cable, the problems went > away. I suspect a hardware error too. The kernel doesn't hang since ping works; switching consoles is not possible, perhaps because that may require a disk access, therefore blocking. Hmmm... I'll try again with other cables. > Tim Kientzle Many thanks, -Farid. -- Farid Hajji -- Unix Systems and Network Management. http://www.farid-hajji.net/address.html Quoth the Raven, "Nevermore." --Edgar Allan Poe.Received on Fri May 09 2003 - 13:37:01 UTC
