I run 2.3.18 SMP, and have two quantum atlas IV connected to a tekram controller using the sym53c8xx driver. The motherboard is abit-bp6 with two celeron 333 processors, no overclocking yet.
I planned to do some tests to find the optimal raid-0 stripe size for my use. (Using bonnie and timed compiles as tests)
The first bonnie run logged a lot of "Got md request, not good..." eventually followed by <6>attempt to access beyond end of device Oct 1 19:52:55 monster kernel: 08:05: rw=1, want=187124, limit=0 Oct 1 19:52:55 monster kernel: Got md request, not good...<6>attempt to access
Bonnie was stuck in uninterruptible sleep after this, attempts to umount or ls on the filesystem get stuck the same way.
The raid-0 had stripe size 4k, I used mke2fs -b 4096 -i 8192 -R stride=1
Is there anything I could do to help debug this? I currently have several empty partitions for experimentation.
