SubjectCrashes reading and writing to disk
Date
From
My machine is an 8 processor Dell P-III 700Mhz with 8GB of memory and
no swap. The disk systems I am using are 3 12 drawer JBODs with 6
disks in a raid 5 arrangement and spanned logical drives attached to
an AMI Megaraid 467 (Elite 1500) controller with a total of 700GB+ of
space formated reiserfs. I am using kernel 2.4.6, compiled with gcc
2.95.4.

Identical crashes occur when using ext2, non-spanned drives (170GB),
or kernel 2.4.4. The failures occur with all 3 JBODs, two different
467 RAID controllers and a 466 RAID controller. I still cannot rule
out hardware failure, because an identical machine with a very similar
setup can pass the following tests without crashing.

When reading or writing to the disk the machine crashes. This can
reliably be repeated with either of the following commands:

dd if=/dev/zero bs=1G count=10 | split -b 1073741824

find /bigfulldisk -type f -exec cat {} \; > /dev/null

The dd crash reliable occurs after writing about 4.5GB of data, but
after a reboot, only about 1.7GB of data has made it to disk (an
emergency sync request just causes the crash to occur again). I am
not sure how much data has been read by the time the find command
causes a crash, but it dies in less than 5 minutes.

Attached below is the ksymoops output from the stack dump. I don't
know if it will be useful, but I can provide any other information
that is requested. As I can recreate the crash at will, please let me
know if there is any before or after information that would be useful
in tracking down the cause of these problems.

ksymoops 2.4.1 on i686 2.4.6. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.6/ (default)
-m /boot/System.map-2.4.6 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
