Check corosync.conf, I'm guessing pcs enabled "two node" mode.

Hi,
pcs cluster stop rhel1
I think both is shutdown.

Did you shut down pacemaker or corosync or both?

Any suggestion please?

I’m making 2 node (rhel1 and rhel2) Linux cluster following Pacemaker-1.1-Clusters_from_Scratch-en-US
After I shutdown one of the node (pcs cluster stop rhel1) , the other partition still have quorum.
While according to document, chapter 5.3.1 ,it should be partition without quorum. (A cluster is said to have quorum when total_nodes<2*active_nodes)
What could be the problem?
Thank you.
