Well, my tape is nice and cool today, but has started failing again.
Backing up say 100MB works, but attempting to grab the whole 1GB
of stuff crashes the system reliably. The symptom is the same,
ncrcontrol shows tps decaying to zero, then I lose all the filesystems.
An interesting message did show up in /var/log/messages, one time
out of four crashes:
Jun 22 10:57:49 geli /kernel: st0(ncr0:6:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted
Jun 22 11:05:13 geli /kernel: st0(ncr0:6:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted
I used pax -wvf /dev/nrst0. I suppose it could be the drive,
unfortunately my easy access is just to FreeBSD systems right now.
Here's dmesg:
