| |
Help is desperately needed to make my backup system back. Sorry for mutiple list posting.
My scsi tape driver suddenly doesn't work. It's about 2 months since last proper backup. I really can't recall what change made it since too many updates happened since then. I issued the command tar cvf /dev/st0 /home After backing up some files, at a fixed point (backing up the file home/PREDATOR/code/bin/xxx which is about 14 Mbyte large), error would happen. Following is the error from system log: ============= Jan 14 02:37:34 localhost kernel: st0: Error with sense data: extra data not valid Current error st09:00: sense key Medium Error Jan 14 02:37:34 localhost kernel: Additional sense indicates Excessive write errors Jan 14 02:37:34 localhost kernel: st0: Error with sense data: extra data not valid Current error st09:00: sense key Medium Error Jan 14 02:37:34 localhost kernel: Additional sense indicates Excessive write errors Jan 14 02:37:34 localhost kernel: st0: Error on write filemark. ================= I'm not sure which info are needed for your help so I include the dmesg message in the following: =================== Linux version 2.2.0-pre5 (root@phoenux) (gcc version egcs-2.90.29 980515 (egcs-1.0.3 release)) #2 Thu Jan 14 00:50:48 /etc/localtime 1999 Detected 199436396 Hz processor.

Any help is grateful and even some suggestion would be good. I really don't know what to try to find the reason. Please CC to me directly when you reply.
