Hi,
We have a cluster whose common storage is a gluster volume consisting of 4 bricks residing on 2 servers (more details at bottom). I have been cleaning out some unneeded files and noticed that most of them came off one brick. When I tried to issue a rebalance I received the following error
[root@mseas-data2 glusterfs]# gluster volume rebalance
data-volume start
volume rebalance: data-volume: failed: Rebalance on
data-volume is already started
However, when I checked the volume status I didn't see any rebalance
[root@mseas-data2 glusterfs]# gluster volume status
Status of volume: data-volume

There are no active volume tasks
But if I use ps, I think I see a possible rebalance process

I have 2 questions
- Is the process I found a gluster rebalance process?
- Is it safe to simply kill the process? Will I need to
clean-up some additional files (e.g. socket files associated
with this process)?
Thanks
