This is weird. Did you start rebalance yourself? What does "gluster volume
rebalance volume1 status" say? Also check if both the nodes are properly
connected using "gluster peer status".

If it says completed/stopped, you can go ahead and add the bricks. Also can
you check if rebalance process is running in your second server (xena?)

BTW, there is *no* master and slave in a single gluster volume :)
