Hello everybody,<br>
<br>
I got the following setup: <a href="http://debian.pastebin.com/Sife0hTz" target="_blank">http://debian.pastebin.com/Sife0hTz</a><br>
<br>
The problem is that when I crm node standby the godfrey node2 everything<br>
nicely migrates to finley node1 and continues to run. (as expected) when<br>
godfrey comes back online and finished synchronising the drbd disks it<br>
tries to take over the resources of finley and fails crashing the iscsi<br>
and drbd systems....<br></blockquote><div><br></div><div>This is something that you should remove from the config, as I understand it, all resources should run together on the same node and migrate together to the other node.</div>

<br>
I have to stop corosync on both nodes and start them again make both<br>
nodes standby and then online godfrey and then online finley to get it<br>
all working again.<br>
<br>
Why doesn't it stay running on the finley node when godfrey comes back<br>
online?<br>
<br>
I am also unable to move the iscsi luns with all his depending resources<br>
to finley and back and forwards by using crm resource move finely.<br>
<br>
Why can't I manually move resources around?<br>

There is probably something I am not doing right but please help me out<br>
i read the Cluster_from_Scratch.pdf,<br>
Pacemaker-1.0-Pacemaker_Explained-en-US and ha-iscsi.pdf.<br>
<br>
Thanks in advance,<br>
<br>
With kind regards,<br>
