Hi
I'm experiencing the following problem while using OCFS2 over DRBD
partition.
My config is the following:
2 servers with pacemaker+corosync stack configured
Debian Lenny/Squeeze mixed:
kernel - linux-image-2.6.32-bpo.5-amd64 (2.6.32-26~bpo50+1)
kernel modules - drbd = 8.3.7 (api:88/proto:86-91) ocfs2 = 1.5.0
packages:
pacemaker = 1.0.9.1
corosync = 1.2.1-2
dlm-pcmk = 3.0.12-2
ocfs2-tools-pacemaker(contains ocfs2_controld.pcmk binary )=1.4.4-3
ocfs2-tools = 1.4.4-3
Kernel trace follows here:

I don't know how to exactly reproduce this bug. Kernel doesn't stall
after hiting this bug. But it is rather annoying and I am worried about
file system consistency.
Any help would be appreciated.
