The dump that comes with RH6.2 (dump-0.4b15-1) barfs on multi volume sets. Simple upgrade to dump-0.4b16-1 makes it work fine.
The problem is that dump-0.4b15-1 doesn't completely close the tape drive, so it can't reopen the drive. Where can one find dump-0.4b16-1? + /sbin/dump -b 32 -d 61000 -B 320 -f /dev/st0 /d5 DUMP: Date of this level 0 dump: Sun May 14 07:32:55 2000 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/hdd5 (/d5) to /dev/st0 DUMP: Label: none DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 1978040 tape blocks on 5137.89 tape(s).
