I cannot seem to get my 2 cluster setup to work they way I want it do, or
believe I think it should.
Issues I have so far are:
First, whenever one of the two cluster nodes goes off-line (forcing them to
do so during testing, but shutdown or stopping openais), then I restart
openais on the cluster that I rebooted or stopped openais on, the resources
restart on the same active node. This cannot happen. I was under the
impression the global variable "resource stickiness" was supposed to be keep
this from happening, I've tried both 0 and INFINITY. I must not be
understanding something correctly. But, its important to me to not have the
resources restart at all if they are already happily running.
Second, if I stop openais on the Active node, the resources do not migrate.
I can see this using LCMC even before I try it. When I stop openais, I can
see in LCMC that the resources will not migrate, but if I try it anyway,
there is an option in the Resource Group to "Remove Migration Constraint".
What is the migration constraint it is removing, and how can I remove it
permanently to make resources migrate like they should?
Using Sles11 SP1 HA.
