How do I determine the cluster's state?

Hi,

 

I have the following scenario:  OVM version 3.4.2, running on a x2 node cluster.  The cluster appears to be faulty. I am trying to determine the cluster's actual state.

 

a) The OVS nodes' console shows:

 

Node 1:

Clustered : Yes

Cluster State: DLM_Ready

 

Node 2:

Clustered : No

Cluster State: Heartbeating    -------------------------------> note the state

 

However, Node 2's o2cb service indicates node is part of cluster (see outputs below):

 

b) The o2cb service cli shows:

 

Node 2 # service o2cb status

Driver for "configfs": Loaded

Filesystem "configfs": Mounted

Stack glue driver: Loaded

Stack plugin "o2cb": Loaded

Driver for "ocfs2_dlmfs": Loaded
