Andrei, thank you!
I tried to find node's scores and have found location constraints for these
3 resources:
pcs constraint
Location Constraints:
Resource: fsmt-28085F00
Enabled on:
Node: vdc16 (score:INFINITY) (role:Started)
Resource: fsmt-41CC55C0
Enabled on:
Node: vdc16 (score:INFINITY) (role:Started)
Resource: fsmt-A7C0E2A0
Enabled on:
Node: vdc16 (score:INFINITY) (role:Started)
but, I can't understand how these constraints were set. Can it be defined
by pacemaker in some conditions or it's only manual configuration?
BTW, how can I see the node's score?
