<p class="MsoNormal"><span style="font-size:11.0pt"> We have a gluster replicate (with arbiter) volumes that we are getting “Transport endpoint is not connected” with on a rotating basis from each of the two file servers, and a third host that has the
arbiter bricks on.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">This is happening when trying to run a heal on all the volumes on the gluster hosts When I get the status of all the volumes all looks good.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> This behavior seems to be a forshadowing of the gluster volumes becoming unresponsive to our vm cluster. As well as one of the file servers have two processes for each of the volumes instead of one
per volume. Eventually the affected file server<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">will drop off the listed peers. Restarting glusterd/glusterfsd on the affected file server does not take care of the issue, we have to bring down both file<o:p></o:p></span></p>

volume issues.<o:p></o:p></span></p>
