Subject: RAID-6: help wanted
Date: Sat, 23 Oct 2004 23:46:46 +0000 (UTC) [thread overview]
Message-ID: <cleqh6$ps4$1@terminus.zytor.com> (raw)
Okay, it's well overdue to do this...
There is currently a data-corruption bug in the RAID-6 md layer
(raid6main.c). I have so far not been successful in locating it,
although it is easily reproducible, thanks to a set of scripts by Jim
Paris. I suspect it is a race condition between raid6d and the rest
of the kernel.
The problem is that I already have way too many projects in flight,
and I *really* would like to focus the time I have on getting
klibc/early userspace integrated. Thus, I don't expect to have any
time at chasing the RAID-6 corruption bug any time soon.
What can be ruled out is errors in the RAID-6 algorithm codes,
however. Those are easily testable in isolation and have a clean bill
of health.
