Hi;
RAID 4/5 does not seem to be working properly with
the patches I have applied from Neil Brown's site
for kernel 2.4.0-test11. When raid5 is in the kernel,
I cannot boot. When it is a module, the oops shown
below occurs with the lsmod showing:
xor (initializing)
You cannot rmmod xor thereafter EVER without rebooting.
>From http://cgi.cse.unsw.edu.au/~neilb/patches/linux/,
I am using:
patch-A-mdinit
patch-C-mdwarn
raid5-debug.patch
(this patch is attached as it is not on the site)
The issue: trying to make a raid level 5 with three
partitions: hda4, hdc4, and hdd4. All are only
500M each. This happens with a variety of raidtools
from RedHat 6.2/7.0 in standard release.
During a insmod/modprobe I receive the following kernel
oops with modutils-2.3.18 or modutils-2.3.20:
