i got a scsi disk error. the system didn't crash but i am wondering
what it all means. thanks in advance for any light you can shed and
tips you can pass on.
i am using linux 2.4.0-test5 (final) with reiserfs 3.6.11 (in
compatibility mode with 3.5.23). it is on a quad ppro system with a
symbios 8751sp card. i am using the sym53c8xx driver version 1.6b
which comes stock with this kernel.
anyhow i am running the iozone benchmark. the iozone program halts
abruptly and complains about a fread command error. i get the
following in my logs (/var/log/messages)
after about an hour of running iozone i get the first of a slew of
mesages

what does "return code = 2" mean? is there a place to look these up?
should i be worried? is my beloved hard drive dying? this is a
rather venerable drive
