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
Gluster process TCP Port RDMA Port Online Pid

Task Status of Volume data-volume

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

-l /var/log/glusterfs/data-volume-rebalance.log
I have 2 questions
1. Is the process I found a gluster rebalance process?
2. 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
