[flexbackup-help] cat: write error: Input/output error

[Richard B. P. <rp...@ki...>]

Being a complete newby at flexbackup, I need some help. The 
system is Linux 2.4.25 with flexbackup 1.2.1a trying to backup 
to an HP T4000s SCSI tape drive.

I am getting:

cat: write error: Input/output error
afio: "-" [offset 200k+0]: Fatal error:
afio: "-": Broken pipe

I tried changing afio to dump and get:

cat: write error: Input/output error
  DUMP: Broken pipe
  DUMP: The ENTIRE dump is aborted.

ERROR from backup, exiting
offending command(s):
dump -0 -a -f - /home | gzip -4 | cat > "/dev/nst0"

In trying to troubleshoot this, the first thing I noticed was 
that the tapedrive doesn't seem to want to change blocksize:

# mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x45 (QIC-3095-MC (TR-
4)).
Soft error count since last status=0
General status bits on (41010000):
 BOT ONLINE IM_REP_EN
# mt -f /dev/nst0 defblksize 32768
# mt -f /dev/nst0 status

4)).

General status bits on (41010000):

I then tried:

#find /home -print | afio -o -z -v -b 32k - | dd ibs=32k obs=32k 
of=/dev/nst0

and get:

dd: writing to `/dev/nst0': Input/output error
6+0 records in
5+0 records out
afio: "-" [offset 224k+0]: Fatal error:
afio: "-": Broken pipe

Any help will be greatly appreciated.
