I'm having problem after I enable (mkraid) my raid partition. It's a
simple 2 SCSI RAID and the partition that I'm dealing with is identical
and unused on both disks. My raidtab entry is this:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
persistent-superblock 1
chunk-size 8
device /dev/sda6
raid-disk 0
device /dev/sdb6
raid-disk 1
I'm running 2.2.13 with the raid-2.2.11 patch compiled into the kernel
(not a module) and using raidtools 0.90.
Here is the path I'm following to get the problems.

--------------------------------
After repeating the process several times I have found that it appears
as though the system has become unstable as soon as I use mkraid. 1 out
of 2 times after I run mkraid I start getting errors like "error in
loading shared libraries: libe2p.so.2: invalid ELF header" when I try
running the mke2fs. Is there something that I have configured
incorrectly (in raidtab?) or is there a step that I need to do that I'm
missing somewhere? Thanks.
