Re: [ClusterLabs] what is the "best" way to completely shutdown a two-node cluster ?
If you gracefully shutdown a node - pacemaker will migrate all resources away so you need to shut them down simultaneously and all resources should be stopped by the cluster. Shutting down the nodes would be my choice.

If there are multiple meta attributes sets, the attribute is set in all of them. If the resource is a clone, all target-role attributes are removed from the children resources.

I'm not sure how "crm resource stop " actually stop a resource. I thought it would set "target-role=Stopped", but I might be wrong. If "crm resource stop" actually use "target-role=Stopped", I believe the resources would not start automatically after setting "stop-all-resources=false". ++ ___ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/

Aren't the VirtualDomains already started by "stop-all-resources=false" ? I wrote a script for the whole procedure which is triggered by the UPS. As i am not a big schellscript-writer please have a look and tell me your opinion. You find it here: https://nc-mcd.helmholtz-muenchen.de/nextcloud/s/rEA9bFxs5Ay6fYG Thanks.
