Hi,
I have a two-node cluster that has more then 2 multi-state drbd
resources on each node. All these resources must be promoted
to master state on the same node because they creates a filesystem for
Xen DomU. Xen will never migrate so I use DRBD 7.x and the most fresh
HA 2.1.2-15 working on SLES10 SP1.
I have created configuration included as a cib2.xml which mainly do what I want.
(for testing only there are 2 drbd resources and IPaddr resource - not
Xen resource)
My problem is I wasn't able to create rule which make:
-if one of the drbd resources fail on the primary node, all of them
should be on the secondary node promoted to master before starting
there Xen.
How can I create such rules?
Could you give same examples?
thanks in advance
