Tape Backup Problem
Hi All,
I've been trying to get tape backup working on a server and almost everytime
I attempt to backup files to the tape drive the machine goes crazy. The
load goes sky high (way over 100.00) and it stops responding to everything.
Maybe someone out there has some insight on the problem.
Specs:
Debian 2.0 with Kernel 2.2.2 running on a Dell with
a Quantum DLT4000 tape drive.
Details:
I attempted to do a test backup a 150meg directory to tape using the tape
backup program "Taper" After about 10min of it running (46% done) the
machines load starting going up and up. I tried to stop the program, and
kill it but was unable to since machine stop responding to my commands via
telnet. The load was very high... --> load average: 246.98, 267.86, 210.28
Then i couldn't even telnet to the machine or anything. Everything appeared
to be down, except that I could ping the machine.
Finally about 30min later I was able to telnet back into the machine.
I noticed several of the following messages in the messages file and also
when i typed "dmesg"
--
May 3 14:23:23 taz kernel: SCSI host 0 abort (pid 228089503) timed out -
resetting
May 3 14:23:23 taz kernel: SCSI bus is being reset for host 0 channel 0.

So a week later I attempted again with tape backup using a different
program. this time i used "Tob".
I did a small test backup using a 20meg directory. It appeared to work
fine. I was able to backup and restore the files.
I then attempted to backup a 2gig directory.
After about 15min the machine went crazy like last time and load went up and
I got locked out so I had to have someone reboot the machine.
Didn't see any error messages in any logs or anything.
Anyone ever expierance this problem?
Anyone have any ideas what might be causing it?
I been trying to figure it out for a couple weeks now with no luck.
Any help is appreciated.
TIA
-Joe
