Carter" Message-Id: <199506222044.NAA00333@geli.clusternet> To: bugs@freebsd.org Subject: st bug again. Sender: bugs-owner@freebsd.org Precedence: bulk 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.
