Can you confirm that pacemaker's stonith is working itself? If you temporarily remove DRBD from pacemaker, stop the DRBD service and then try crashing a node, does it get rebooted? I do this test by calling 'echo c > /proc/sysrq-trigger', which causes the node to immediately panic.<br>
<br>
The 'out of memory' issue is not something I've ever seen before. Once we confirm that pacemaker's fencing is working, we can look into it.<br>
<br>
What version of pacemaker, corosync and drbd are you using?<span class="HOEnZb"><font color="#888888"><br>

PS - If fencing fails, DRBD _should_ remain blocked, so that behaviour is expected and good.<div class="HOEnZb"><div class="h5"><br>

Dear Digmer,<br>

Now , when i drop the DRBD link in n2.stg node , these logs appear :<br>

note "out of mem, failed to invoke fence-peer helper"<br>
<br>
Fencing didn't happen , but I/O is blocked .<br>
<br>
<br>
Where may the problem ?<br>

Hi<br>
I installed cluster (corosync+pacemaker+drbd) , and i am using IPMI as a<br>
fencing device .<br>
I have 2 link , one of them for drbd , and pacemaker use both links .<br>
<br>
When I cut the 2 links (by drop connection by iptables) , fencing is<br>
working good , but when i cut the drbd link (also by iptables) nothing<br>
fencing happen .<br>
<br>
why?<br>

<br>
Do you have DRBD configured in pacemaker and did you set the<br>
fence-handler to be /path/to/crm-fence-peer.sh?<br>
<br>
If this doesn't resolve the issue, please shared you 'drbdadm dump' and<br>
pacemaker configurations.<br>
