<p class="MsoNormal"><span style="font-size:11.0pt">I’ve got a replicated volume with three bricks (“1x3=3”), the idea is to have a common set of files that are locally available on all the machines (Scientific Linux 7, which is essentially CentOS 7) in a
cluster.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I tried to add on a fourth machine, so used a command like this:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="p1"><span class="s1">sudo gluster volume add-brick dockervols replica 4 webserver8:/data/gluster/dockervols force</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">but the result is:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: removing the new brick (this also fails) and trying again.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: checking the logs. The log files are not enlightening to me – I don’t know what’s normal and what’s not.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: deleting the brick directory from previous attempt, so that it’s not in the way.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: restarting gluster services<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: rebooting<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Tried: setting up a new volume, replicated to all four machines. This works, so I’m assuming it’s not a networking issue. But still fails with this existing volume that has the critical data in it.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Running out of ideas. Any suggestions? Thank you!<o:p></o:p></span></p>
