I'm trying to back up a 14GB RAID-5 array (19981005 snapshot
drivers/tools) to a 12/24GB DAT drive using dump. Here's what happens:
running /sbin/dump 0ufbB /dev/nst0 32 18874368 /raid
DUMP: Date of this level 0 dump: Thu Nov 5 15:19:53 1998
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/md0 (/raid) to /dev/nst0
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 13976887 tape blocks on 0.74 tape(s).
DUMP: dumping (Pass III) [directories]
DUMP: dumping (Pass IV) [regular files]

DUMP: bread: lseek fails
DUMP: short read error from /dev/md0: [block -134215688]: count=4096, got=0
DUMP: bread: lseek2 fails!
DUMP: short read error from /dev/md0: [sector -134215688]: count=512, got=0
DUMP: bread: lseek2 fails!
DUMP: short read error from /dev/md0: [sector -134215687]: count=512, got=0
DUMP: bread: lseek2 fails!
[and so on, ad infinitum]
is this a problem with the RAID drivers, or am I just seeing Linux
barf with an oversized volume? Is there a solution besides
repartitioning to smaller volumes (and how should I proceed with that,
given that I can't dump the filesystem..?)
