Description RamaKasturi 2013-11-21 13:05:48 UTC 
Description of problem:
When glusterd is down in one of the node, clicking on stop rebalance throws an error saying "Error while executing the action stopRebalanceGlusterVolume : Command execution failed."

Version-Release number of selected component (if applicable):
rhsc-2.1.2-0.24.master.el6_5.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create a distribute volume and start it.
2. start rebalance on the volume.
3. Once rebalance is started, stop glusterd in one of the node by using the command "service glusterd stop".
4. Now click on the drop down button in the activities column and click stop.

Actual results:
It gives an error saying "Error while executing the action stopRebalanceGlusterVolume : Command execution failed."

[root@localhost ~]# gluster volume rebalance vol_dis stop --xml

2

As,can be seen,rebalance stop command is not returning any xml and hence this issue.So,it is a gluster bug again.

Comment 4 RamaKasturi 2013-12-13 12:17:26 UTC 
Verified and works fine with cb11 build rhsc-2.1.2-0.27.beta.el6_5.noarch.

After making glusterd down in one of the node , and try stopping rebalance , rebalance stops.

Attaching the screenshot for the same.
