Welcome to communities....
Thanks for pasting the screenshots it helps me understand better.
I see the management lif of node "meridian-clus-01" as down (you can check why it is down and correct it)
The command cluster create is not required. I see the cluster already made.
Try running the command -- cluster show
This would show the cluster and the two nodes
Here is what has happened. (correct me if this is not the case)
a) when node1 - meridian-clus-01 was booted cluster create command was used to create the cluster
b) and when node2 was booted up cluster JOIN was issued to join the first node.
hence the cluster has two nodes.
You are trying to create the cluster again which is not right as the cluster has been made already
hope this helps
