Well, my 2.0.20 kernel, up 24 days, is about to go down 8-(
I was on another box, trying to restore a tape:
rsh [box-with-tape] cat /dev/st0 | tar xzvf -
Alas, the data on the tape wasn't compressed, so gzip barfed, tar
barfed, and the rsh ended (on the tar box, not the cat box). Leaving us
with the cat on the remote machine singing along. Now the tape drive
doesn't think it's busy (no activity, and I can eject the tape). The
Linux box has a different view of things - mt reports the device as
busy, and the cat's doing something. kill and kill -9 are completely
ineffective, so I presume the process is never coming up out of the
kernel for air. Is this normal and expected behavior? How does one kill
such a task?
The details:
Configuring Adaptec (SCSI-ID 6) at IO:330, IRQ 10, DMA priority 5
scsi1 : Adaptec 1542
scsi : 2 hosts.
Vendor: HP Model: C1130A Rev: 3540
Type: Processor ANSI SCSI revision: 02
Vendor: WANGTEK Model: 6130-HS T Rev: 4G16
Type: Sequential-Access ANSI SCSI revision: 02
Detected scsi tape st0 at scsi1, channel 0, id 5, lun 0
The kernel is stock 2.0.20, the 1542 and st drivers are modules. There's
also an Adaptec 2940UW running disks, not a module. The HP 'processor'
is a scanner, for the curious.
Please copy me on responses, as I'm only subscribed to the aic7xxx list.
Thanks in advance.
