Hi,
I have created a simple two-node cluster with 2 multi-state drbd
resources on each node. I use DRBD 7.x and the most fresh HA 2.1.2-24
working on SLES10 SP1.
The only rules for my cluster I need are:
- resources must be promoted to master state on the same node (IT WORKS).
- if one of the drbd resources fail on the primary node:
- the rest of drbd resources on the primary mode must be demoted and
- on the secondary node all drbd resources schould be promoted to
master.
I have tried many rsc_colocation rules but without succes.
How to get such result?
The second question is:
If I want node to reboot when a drbd resource stop fails should I have
stonith resource (external/ssh)?
Or should be enough this operation <op id="dummy-resource-stop-id"
name="stop" on_fail="fence"/> for drbd resource?
Below is my cib.xml. Thanks for advance.
