Since the existing configuration is 2 X 2 and if you are willing to continue to make this volume a distribute-replicate one, you should add two bricks saying gluster v add-brick videos replica 2 <brick1> <brick2> However, I think you could still convert it from replica 2 to replica 3 with the command what you attempted. Can you share the glusterd log file of all the nodes to debug it further.
