Hi,
We have a custom Master-Slave resource running on a 3-node pcs cluster on
CentOS 7.1
As part of what is supposed to be an NDU we do update some properties of the
resource.
For some reason this causes both Master and Slave instances of the resource to
be restarted.
Since restart takes a fairly long time for us, the update becomes very much
disruptive.
Is this expected?
We have not seen this behavior with the previous release of pacemaker.
