[ClusterLabs] crm resource stop VirtualDomain - how to know when/if VirtualDomain is really stopped ?
Hi, i'm trying to write a script which shutdown my VirtualDomains in the night for a short period to take a clean snapshot with libvirt. To shut them down i can use "crm resource stop VirtualDomain". But when i do a "crm resource stop VirtualDomain" in my script, the command returns immediately. How can i know if my VirtualDomains are really stopped, because the shutdown may take up to several minutes. I know i could do something with a loop and "crm resource status" and grepping for e.g. stopped, but i would prefer a cleaner solution. Any ideas ? Thanks.
