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

<br>
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.<br>
<br>
Any help would be appreciated.<br>
