Hi Susan,

Thank you for the response.

> 3. Is rebalance process still running? If yes can you point to specific mem usage by rebalance process? The high mem-usage was seen during rebalance or even post rebalance?

I would like to restart the rebalance process since it failed… But I can’t as the volume cannot be stopped (I wanted to reboot the servers to have a clean testing grounds).

Here are the logs from the three nodes: http://paste.fedoraproject.org/256183/43989079

Maybe you could help me figure out how to stop the volume?

This is what happens 

[root at highlander ~]# gluster volume rebalance live stop
volume rebalance: live: failed: Rebalance not started.

[root at highlander ~]# ssh stor105 "gluster volume rebalance live stop"
volume rebalance: live: failed: Rebalance not started.

[root at highlander ~]# ssh stor104 "gluster volume rebalance live stop"
volume rebalance: live: failed: Rebalance not started.

[root at highlander ~]# ssh stor106 "gluster volume rebalance live stop"
volume rebalance: live: failed: Rebalance not started.

[root at highlander ~]# gluster volume rebalance live stop
volume rebalance: live: failed: Rebalance not started.

[root at highlander ~]# gluster volume stop live
Stopping volume will make its data inaccessible. Do you want to continue? (y/n) y
volume stop: live: failed: Staging failed on stor106. Error: rebalance session is in progress for the volume 'live'
Staging failed on stor104. Error: rebalance session is in progress for the volume ‘live'
