<pre wrap="">From what I see you have a dual primary setup with failover on the third
node, basically if you have one drbd resource for which you have both
ordering and collocation, I don't think you need to "improve" it, if it
ain't broke, don't fix it :)

No, I don't have Dual primary. My DRBD is in Single-Primary mode for
both DRBD resources.
I use N+1 setup. I have 2 resource group which have unique Primary
and shared secondary.
pbx_service_01 resource group has primary node-01 and secondary node-03
pbx_service_02 resource group has primary node-02 and secondary node-03
I use asymmetric cluster with specific location constraints in order
to implement the above.
The DRBD resource will never be in primary mode on 2 nodes at the same time.
I have set specific collocation and order constraints in order to
"bond" DRBD ms resource to the appropriate resource group.
I hope it is clear now.
Cheers and thanks for looking at my conf,
Pavlos

True, my bad, Dual-Primary does not apply to your setup, I formulated
it wrong, I meant what you said :)<br>
