Hi,
what would you consider to be the best way for removing a node temporary from the cluster, e.g. for installing updates ?
I thought "crm node maintenance node" would be the right way, but i was astonished that the resources keep running on it. I would have expected that the resources stop.
I think "/etc/init.d/openais stop" seems to be a good solution. The resources are stopped and eventually moved to the other node, then i can install updates, change hardware ... and reboot it afterwards.
Or prefer "crm node standby" ?
Thanks.
Bernd
