Hi,<br>
<br>
We have a cluster whose common storage is a gluster volume
consisting of 5 bricks residing on 3 servers.<br>
</p>
<ul>
<li>Gluster volume machines</li>
<ul>
<li>mseas-data2: CentOS release 6.8 (Final)</li>
<li>mseas-data3: CentOS release 6.10 (Final)</li>
<li>mseas-data4: CentOS Linux release 7.9.2009 (Core)</li>
</ul>
<li>Client machines</li>
<ul>
<li>CentOS Linux release 7.9.2009 (Core)</li>
</ul>
</ul>
<p>More details on the gluster volume are included below.<br>
<br>
We were recently trying to gunzip a file on the gluster volume and
got a "Transport endpoint is not connected" even though every
test we try shows that gluster is fully up and running fine. We
traced the file to brick 3 in the server mseas-data3. We have
included the relevant portions of the various log files on the
client (mseas) where we were running the gunzip command and the
server hosting the file (mseas-data3) below the gluster
information<br>
<br>
What can you suggest we do to further debug and/or solve this
issue?<br>
<br>
Thanks<br>
Pat<br>
