The "notice:" part is the severity of the message -- "error:" or
"warning:" is bad, but anything else is purely informational.

In this case, this message indicates that you have
no-quorum-policy=ignore configured. It will be printed every time one of
the pacemaker daemons or tools reads your configuration, and has nothing
to do with your resource problem.

You'd need to look at a much larger chunk of the logs, typically on more
than one node. The cluster will elect one node to be the "Designated
Controller" (DC), and that node's logs will have essential information
about the decision-making process.
