Tested with RHEVM 3.6.2.5-0.1.el6 and with RHGS 3.1.2 RC 1. Created a distributed volume and rebalance option is enabled 2. Created a pure replicate ( replica 2 or replica 3 ) volume and rebalance options is disabled 3. Created a disperse volume from the gluster CLI and waited for it to sync in RHEVM UI, and rebalance option is disabled here too 4. Expanded the disperse volume to a distributed disperse volume and rebalance option now got enabled 5. Created a distributed replicate volume, and rebalance option is disabled here Based on the above results, moving this bug to VERIFIED Note : RHGS 3.1.2 has vdsm 4.16.z and it can't be added to RHEVM 3.6 So I have used the custom build vdsm & vdsm gluster of build 4.17.16
