<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Let’s say I have a 5 node converged cluster of oVirt & glusterFS with a replica count of “3”.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Host1 - replica</p>
<p class="MsoNormal">Host2 - replica</p>
<p class="MsoNormal">Host3 - replica</p>
<p class="MsoNormal">Host4</p>
<p class="MsoNormal">Host5</p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"> </span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif">If I spin a VM up on Host1 – does the first replica get created local to that server?</span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"> </span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif">In the event I move the VM to another host, does the replica of the disk follow the VM so essentially it’s writing to a local copy first or does it “always” write across
the network.</span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"> </span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif">For example, with VMware, the disk will follow the VM to the hypervisor you move it to so that the writes are essentially “local”.
</span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"> </span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif">I have not been able to find anything on the internet or in the documentation that specifies how this process works. Ideally, you wouldn’t want a VM residing on Host1 that
accesses its disk on Host3. Multiple that by hundreds of VM’s and it would create a ton of unnecessary network congestion.</span></p>
