Hi,

Environment: NetBSD 1.5, i386, Intel motherboard, 128 MB memory, Exabyte
Eliant 8mm tape drive on SCSI.

This was working until recently. There are two possibilities here.

1) The system may have developed a hardware problem.

2) The dump script is flawed and the flaw is causing a problem now
   because the partitions have exceeded the size I specify with the
   dump parameters.

Below are the parameters for dump, the first part of the output from the
cron job (the rest is more failed dumps), and the output of df.

The script usually continues with /var, /home, and /var/mail.

Am I using the correct parameters for the Eliant? Should I be using the -B
option and forgetting about length and density?

Thanks.


b=126
d=108000	# original Exabyte uses 54000, Eliant is double that
s=8500		# for 160m tape (note that 160*6000/112=8571)
		# standard 112m uses 6000
f=/dev/nrst0
dump 0ubdsf $b $d $s $f /
