I want to create 2 server glusterfs but I don't know why when I run command gluster peer probe server1
they have error. Firewalld is active.
# gluster peer probe server1
peer probe: fail: Probe returned with Transport endpoint is not connected
In case the problem is with the firewall, you should be able to open the firewall ports with the following command:
# firewall-cmd --zone=<zone_name> --add-service=glusterfs [--permanent]
You might want to test first if disabling the firewall works, and then tune the firewall rules and services for your environment.
