[1.] One line summary of the problem:
Linux 2.2.19 system crash with Oops in scsi_do_cmd during mirror rebuild
on megaraid
[2.] Full description of the problem/report:
Seconds after starting a rebuild of a mirrored partition on a megaraid
controller, the
system crashed. It might be reproducable but since this is a production
system I have
not attempted to do it again.
Before I attempted to rebuild the mirror set, I got several kernel
messages like this
kernel: scsidisk I/O error: dev 08:11, sector 71077808
This is on a mirrored partition that the megaraid utility verified to be
flawless.
After the crash, fsck could not repair the file system completely - when
it tried
to write new block descriptors, it got "short write" write errors.
Again, the
megaraid bios said the mirror set was healthy and the individual disks
had not
returned any hardware errors. "mke2fs" had no problems to write
anywhere, and it
also stopped the error messages.
[3.] Keywords (i.e., modules, networking, kernel):
filesystem, scsi, megaraid, kupdate
[4.] Kernel version (from /proc/version):
Linux version 2.2.19 (root@localhost) (gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release)) #1 SMP Tue Apr 3 21:56:41 CEST 2001
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
I had to type this in by hand and some of it had scrolled of screen so
you will have
to forgive any minor errors-- couldn't you guys please put one of the
crash
dump patches into the mainstream kernel?
