Hi,

i'm currently changing a bit in my cluster because i realized the my configuration for a power outtage didn't work as i expected.
My idea is currently:
- first stop about 20 VirtualDomains, which are my services. This will surely takes some minutes.
I'm thinking of stopping each with a time difference of about 20 seconds for not getting to much IO load.
and then ...
- how to stop the other resources ?
- put the nodes into standby or offline ?
- do a systemctl stop pacemaker ?
- or do a crm cluster stop ?

And what is if both nodes are running ? Can i do that simultaneously on both nodes ?
My OS is SLES 12 SP5, pacemaker is 1.1.23, corosync is 2.3.6-9.13.1

Thanks for your help.

Bernd
