Yesterday afternoon, I spontaneously started getting errors like
this:
kernel: scsidisk I/O error: dev 08:12, sector 7096
kernel: scsidisk I/O error: dev 08:11, sector 540720
and the system frooze. My root partition was on sdb and I didn't
have problems with sda as indicated above with numbers 11 and 12
(nor with sdc, by the way) so I'm a bit confused by this.
The controller is a AHA-2940 Ultra.
sda - Seagate Baracuda 4.5 GB Ultra-SCSI
sdb - Seagate Baracuda 9.1 GB Ultra LVD ST39173LW (I use a 68pin-50pin adaptor)
sdc - old Seagate 1GB Fast-SCSI ST31200N
By coincidence, I upgraded the kernel from 2.0.37 (patched with
AIC7XXX 5.1.11) to a 2.2.15 patched with AIC7XXX 5.1.29 (Debian's
2.2.15 package) three days ago. I don't know if if this is
related. Problems only started spontanously yesterday.
I rebooted the 2.0.37 kernel, got an I/O error once (so perhaps
not related to the aic7xxx driver?), tried again and managed to
copy my root partition (about 1 GB) to an IDE disk. I wasn't
able to get this far with the 2.2.15 kernel. I booted 2.2.15 off
of the IDE disk after unpluging the troublesome sdb disk. So
far, it's smooth sailing with the other two SCSI disks on kernel
2.2.15.
Do I have a bad disk?
Has the driver changed such that a LVD disk on a plain Ultra
controller might be a problem?
Any tests I can do?
Any clues appreciated,
Thanks!
