<p>Hi,</p>
<p>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</p>
<p><tt>[root@mseas-data2 glusterfs]# gluster volume rebalance
data-volume start</tt><tt><br>
</tt><tt>volume rebalance: data-volume: failed: Rebalance on
data-volume is already started</tt><tt><br>
</tt><br>
</p>
<p>However, when I checked the volume status I didn't see any
rebalance</p>
<p><tt>[root@mseas-data2 glusterfs]# gluster volume status</tt><tt><br>
</tt><tt>Status of volume: data-volume</tt><tt><br>
</tt><tt>Gluster process TCP Port
RDMA Port Online Pid</tt><tt><br>

</tt><tt> </tt><tt><br>
</tt><tt>Task Status of Volume data-volume</tt><tt><br>
</tt><tt>------------------------------------------------------------------------------</tt><tt><br>
</tt><tt>There are no active volume tasks</tt><tt><br>
</tt><br>
</p>
<p>But if I use ps, I think I see a possible rebalance process</p>

</tt><br>
</p>
<p>I have 2 questions</p>
<ol>
<li>Is the process I found a gluster rebalance process?</li>
<li>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)?<br>
</li>
</ol>
<p>Thanks<br>
