Subject: 2.4.27: md RAID1 oops on alpha revisited
Date: 28 Sep 2004 01:44:24 +0200 [thread overview]
Message-ID: <ujcr7onnup3.fsf@nfsd.linpro.no> (raw)
2.4.27: md RAID1 oops on alpha revisited
We have a Compaq Alphaserver DS10 466 MHz running Debian Woody with a
self compiled 2.4.27 from kernel.org. We have not been able to make it
run stable on md RAID1. It always crashes in less than an hour
uptime, presumely while stressing the RAID code. Running on single
disks, it's rock stable.
While debugging the problem and googling for answers, we came across
very similar problems, posted to lkml by Norbert Preining 2004-03-27
(http://www.uwsg.iu.edu/hypermail/linux/kernel/0403.3/0837.html)
According to that thread, things should work ok with a newer gcc. It
also seems like some version of the patch mentioned has gone into the
kernel. We rebuilt the kernel using gcc-3.3.4. The result: The machine
crashes maybe a little later, but always within an hour or so.
As the bootlog shows, we booted with degraded mirrors, and added the
other parts of the mirrors after booting. (This to make sure the box
doesn't oops till it's done booting.)
The machine locks up after the oops, so we had to run ksymoops after a
reboot without raid, but with the same kernel and same modules loaded.
Below is ver_linux, cpuinfo, meminfo, some info from gcc, output from
lsmod, the oops run though ksymoops, and the bootlog from dmesg. The
oops was captured using a serial console.
Is it possible to make this thing run stable on md RAID1?

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
