The primary goal is to transparently update software in cluster. I just did HA suite update using simple RPM and observed that RPM attempts to restart stack (rcopenais try-restart). So
a) if it worked, it would mean resources had been migrated from this node - interruption b) it did not work - apparently new versions of installed utils were incompatible with running pacemaker so request to shutdown crm fails and openais hung forever. The usual workflow with one cluster products I worked before was - stop cluster processes without stopping resources; update; restart cluster processes. They would detect that resources are started and return to the same state as before stopping. Is something like this possible with pacemaker?
