I would like to create 3 nodes cluster using SUSE 15 SP5. The second node could be joined to the new cluster. However, the third node can’t be joined with the below error. Please advise how I can fix it. Thanks in advance.

Did you set up the cluster on the first two nodes as root or a user with sudo privileges?

When first creating the cluster the “crm cluster init” command checks for SSH keys for passwordless access and should have generated public and private SSH keys if they didn’t exist.

The problem was fixed after using the hostname instead of IP address.

crm cluster join -c ocsf2-node01

Thanks.
