I'm trying to do a dump to a 35 GB DLT drive. The filesystem is only
about 1.6 GB, but dump claimes it needs around 40 tapes for the backup.
What am I doing wrong?
> dump -f /dev/nrsa0 /usr
DUMP: Date of this level 0 dump: Mon Jun 11 23:13:53 2001
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/amrd0s1f (/usr) to /dev/nrsa0
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 1613523 tape blocks on 40.99 tape(s).
DUMP: dumping (Pass III) [directories]
DUMP: dumping (Pass IV) [regular files]
DUMP: Closing /dev/nrsa0
DUMP: Change Volumes: Mount volume #2
DUMP: Is the new volume mounted and ready to go?: ("yes" or "no") no
DUMP: Do you want to abort?: ("yes" or "no") yes
DUMP: The ENTIRE dump is aborted.

And this should be the relevant part of dmesg.
