Hi,<br>
<br>
I know, no fencing configuration creates issue.<br>
But the current scenario is due to fencing??<br>

Maybe, maybe not. I can say that *not* having it will make solving the problem much more difficult. Please get it working, it's pretty easy and it will make your life a lot easier.<span class=""><br>

The syslog isn't revealing much about the same.<br>
I would love to configure fencing but currently need some solution to<br>

It is critical, yes. Please add it, test it and then hook DRBD into it.<span class=""><br>

That is quite old. Can you update to 8.3.16? Also, what version is pacemaker and corosync?<br>

Hi all,<br>
<br>
Facing a strange issue which I'm not able to resolve as<br>
I'm not<br>
sure where what is going wrong as the logs is not giving away<br>
much to my<br>
knowledge.<br>
<br>
Issue -<br>
Have configured 2 Node Clustering, have attached the configuration<br>
file(New CRM conf of BIC.txt).<br>
<br>
If Server2 which is primary is shutdown(forcefully by turning<br>
off the<br>
switch), Server1 restarts within few seconds and starts the<br>
resources.<br>
Even though the Server1 restarts and starts the resources the<br>
time taken<br>
to recover is too long to convince the clients and the current<br>
working<br>
is erroneous is what I feel.<br>
<br>
Have attached the syslog with this mail.(syslog)<br>
<br>
Do go through the same and let know a solution to resolve the<br>
same as<br>
the setup is in clients place.<br>
<br>

You really need fencing, first and foremost. This will cause the<br>
survivor to put the lost node into a known state and then safely<br>
begin taking over lost services. Do your nodes have IPMI (or iRMC,<br>
iLO, DRAC, etc)? If so, setting up stonith is easy.<br>
<br>
Once it is setup, configure DRBD to use the fence-handler<br>
'crm-fence-peer.sh' and change the fencing policy to<br>
'resource-and-stonith'. Without this, you will get split-brains and<br>
fail-over will be unpredictable.<br>
<br>
Once stonith is configured and tested in pacemaker and you've hooked<br>
DRBD's fencing into pacemaker, see if you problem remains. If it<br>
does, on both nodes, run: 'tail -f -n 0 /var/log/messages', kill a<br>
node and wait for things to settle down. Share the log output here.<br>
<br>
Please also tell us your OS, pacemaker, drbd and corosync versions.<br>
