[ClusterLabs] Phantom Node

I can't seem to track this down and am hoping someone has seen this or can
tell me what's happening.

I have a 2 node test cluster, node01.private and node02.private.

[root at node01 ~]# cat /etc/hosts   localhost
::1         localhost   node01.private  node02.private  cluster.private

The issue is when I run 'pcs status' it shows both nodes online but a 3rd
node, node01, to be offline:

[root at node01 ~]# pcs status
Cluster name: cluster.private

    <clusternode name="node02.private" nodeid="2">

          <device name="pcmk" port="node02.private"/>
    <fencedevice agent="fence_pcmk" name="pcmk"/>
[root at node01 ~]#

Everything appears to be working correctly, just that phantom offline node
shows up.
