I've got a Seagate TapeStor 8000 (TR4) as sa0: sa0 at ahc0 bus 0 target 2 lun 0 sa0: Removable Sequential Access SCSI-2 device I've used the drive to successfully backup nearly 3Gb of crap on my windud 98 partition of my machine and now that I bought a few more tapes, it was time to dump the more important filesystems (i.e. all the BSD ones :). I put in a fresh tape, do "mt erase" and things seem ok. I dump / and that goes without a hitch. Then I prepare to dump /home and the wierdness begins. This is the dump(8) output: root@whale [~]<26># dump -0au -f /dev/nrsa0 / DUMP: Date of this level 0 dump: Thu Sep 16 20:37:08 1999 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rda0s2a (/) to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 30879 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: DUMP: 30906 tape blocks on 1 volume DUMP: finished in 39 seconds, throughput 792 KBytes/sec DUMP: level 0 dump on Thu Sep 16 20:37:08 1999 DUMP: Closing /dev/nrsa0 DUMP: DUMP IS DONE root@whale [~]<27># dump -0au -f /dev/nrsa0 /home DUMP: Date of this level 0 dump: Thu Sep 16 20:38:16 1999 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rda0s2h (/home) to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 63773 tape blocks. at this point, the tape drive write light blinks on and off at about 1 Hz and the muskrat-sounding stepper motors (or whatever they are) are making noise at about 1 Hz, but no further output from dump is given. This filesystem is only 2 times as big as / and / dumped in about 40 seconds. I would have expected my /home partition to finish dump(8)ing in roughly twice that amount of time. However, I've left it running for about 30 minutes now .... I can reliably repeat this behavior. If I erase the tape (or use a new one) I can dump any filesystem of any size, but cannot dump another filesystem right after that. I get the same bizzare behavior described above. I cannot kill the dump either. Even doing a "shutdown" won't kill it and the only thing to get the drive from doing the 1 Hz thing is to power it down. After grepping the archives, it seems that the dump commands I'm using are correct (the -a is supposed to be "auto-size"). Is there some sort of "mt" command that I need to be doing between dump(8) processes so that I can dump many different filesystems onto a single tape? BTW: nothing shows up in my /var/log/messages file regarding this device freaking out. Help.
