<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">Actually
we are using glusterfs as shared storage solution within VM clusters
running within openstack (in the future it is true, it will be
containers).
</span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">Currently our use-case involves glusterfs 3.6.9 utilizing 3 servers with replication 2 (third server has no bricks).</span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black"> </span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">Our main problems come from the split-brain files and memory usage of glusterfsd as well as glusterfs fuse clients.</span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">For the first one we are thinking to use replica 3 along with client quorum (now only server quorum is used).</span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">For
the second (mem usage, which is most important), we are trying to
cherry pick commits from 3.7/3.8 series, in order to check if there is
any decrease in the
mount of memory server and clients use.</span></p>
<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">We are trying to upstream them as well for the community in the release 3.6, but smoke builds in BSD have blocked us.</span></p>

<p class="MsoNormal"><span style="font-size:11pt;font-family:"Corbel",sans-serif;color:black">I
have also included Vaggelis Polakis in the conversation, who is the
architect in the team and has a better overview of all our issues with
gluster.</span></p>
