Many thanks to Yan, Eddie and Serge!
What I am trying to do is to implement a CLI command to migrate the resource
to the backup node.
From the replies, my understand is: there is no single command can do that.
No matter what, I need to do:
1. "standby on node1"
2. after a while
3. "standby off node1"
or
1. "crm_source -M -r node1"
2. after a while
3. "crm_source -M -r node1 -U"
Any existing tool can promptly inform me that the "step 1" is done?
I am sending messages to heartbeat mgmt module because I did not know
crm_tools. Looks the crm_admin tools
are you guys recommend, is that correct?
Thanks!
