Package: linux-image-2.6.35.6
Version: 2.6.35.6-10.00.Custom
Severity: important
Hello.
First of all - this it my first bugreport to debian and I sorry if I do something wrong - just tell me what need to fix in it.
I have 2 servers Dell 2950 and try to use it as a email cluster.
I use DRBD with OCFS2 over it. Both nodes is reboot on heavy load every time.
I report bug for a package linux-image-2.6.35.6 but it is not true - I have this problem on 2.6.26(stable) and 2.6.32(testing). I just try latest kernel to be sure.
I try ocfs2-tools from stable and from testing - nodes reboot. I try DRBD8 from backports and then on 2.6.32 native and compile DRBD-8.3.8 from sourse with 2.6.35-6 - nodes reboot.
So I think it is a kernel relaited but I can be really wrong. Im not sure what couse this reboots.
What I do:
1) Create a DRBD md on both nodes
drbdadm create-md drbd0
2) Sync it
drbdadm -- --overwrite-data-of-peer primary drbd0
drbdsetup /dev/drbd0 syncer -r 110M
3) Make both primary
drbdadm primary drbd0
4) Make FS
mkfs.ocfs2 -L ocfs2_drbd -N 2 -T mail --fs-feature-level=max-features /dev/drbd0
5) Mount it on both nodes
mount /var/spool/dovecot
(fstab options - nodev,noauto,noatime,data=writeback)
6) Make folders for test
mkdir /var/spool/dovecot/iozone1
mkdir /var/spool/dovecot/iozone2
7) Start IO test on both nodes in different folders
iozone -RK -t 4 -s 10g -i 0 -i 1 -i 2 -b /tmp/`hostname`.xls
8) Allways got reboot after 30-180 min. Sometimes with stack trace and halt but not everytime.
OCFS2 partition seems to work ok at normal work.
P.S. If i was wrong to write this in sid like system - just tell me. This bug easly repeatable on stable or testing.
