Red Hat Bugzilla – Bug 191933
Oops with RAID0
Last modified: 2007-11-30 17:07:25 EST
Description of problem:
I have a system with 2 3ware 9550SX-12 boards, each running 11 disk hardware
RAID 5s. I want to do a stripe across these 2 large (>2TiB) disks. I
can create the array just fine, but the system Oopses every time I try
to mke2fs the array. Running mke2fs on 1 of the "disks" works just fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. mdadm -C /dev/md0 -l 0 -c 512 -n 2 /dev/sd[bc]1
2. mke2fs -b 4096 -j -m 0 -E stride=128 -O dir_index -T largefile4 /dev/md0
Oops (see attached serial console capture)
It should chug right along.
I asked on the linux-raid list, and Neil Brown pointed me at this patch
f;h=1eb29128c644581fa51f822545921394ad4f719f>. I created a custom kernel from
the SRPM with this patch, and the problem seems to be resolved.

I've posted the patch internally for review/possible inclusion in the next RHEL
update. Thanks for the consice report and pretested fix.
No problem. Thank *you* for reminding me that this fix isn't in u4. I was
about to update that server. :)
