Bug 1881823

Getting the following error message while adding a brick from different node to the volume.

"volume add-brick: failed: Multiple bricks of a replicate volume are present on the same server. This setup is not optimal. Bricks should be on different nodes to have best fault tolerant configuration. Use 'force' at the end of the command if you want to override this behavior. "


Provide version-Release number of selected component (if applicable):
glusterfs-server-6.0-45.el8rhgs.x86_64


Is this issue reproducible? If yes, share more details.:
Always

Steps to Reproduce:
1.Create a replica 2 volume.
2.Add a brick from different node to convert it to replica 3 volume.

Actual results:
Getting an error message.
"volume add-brick: failed: Multiple bricks of a replicate volume are present on the same server. This setup is not optimal. Bricks should be on different nodes to have best fault tolerant configuration. Use 'force' at the end of the command if you want to override this behavior. "
However, with force option, add-brick is successful.
 
Expected results:
Error message should not be seen as the brick to be added is from a different node.
 
 

Additional info:

[root@dhcp47-141 ~]# gluster vol create vol2 replica 2 10.70.47.141:/bricks/brick2/vol2_brick2 10.70.47.41:/bricks/brick2/vol2_brick2
Support for replica 2 volumes stands deprecated as they are prone to split-brain. Use Arbiter or Replica 3 to avoid this.
