2. Any recommendations and or changes I need to make on the gluster

PS: My hosts that are connecting to the Gluster cluster using the GlusterFS client and are bare-metal servers used for docker containers. Also the MTU on these are set to 1500 instead of 9000. <br id="yui_3_16_0_ym19_1_1472226940299_4239">
