Hello,
I am contacting you because I have a problem with my cluster and I
cannot find (nor understand) any information that can help me.
I have a 2 nodes cluster (pacemaker, corosync, pcs) installed on CentOS
7 with a set of configuration.
Everything seems to works fine, but here is what happens:
* Node1 and Node2 are running well with Node1 as primary
* I reboot Node2 wich is passive (no changes on Node1)
* Node2 comes back in the cluster as passive
* corosync logs shows resources getting started then stopped on Node2
* "crm_mon" command shows some ressources on Node1 getting restarted
I don't understand how it should work.
If a node comes back, and becomes passive (since Node1 is running
primary), there is no reason for the resources to be started then
stopped on the new passive node ?
One of my resources becomes unstable because it gets started and then
stoped too quickly on Node2, wich seems to make it restart on Node1
without a failover.
I tried several things and solution proposed by different sites and
forums but without success.
Is there a way so that the node, which joins the cluster as passive,
does not start its own resources ?
thanks in advance
Here are some information just in case :
