<p>Hello.</p>
<p>Out of curiosity, why do you and people in general use more
replica 3 than replica 2 ?</p>
<p>If I understand correctly this seems overkill and waste of
storage as 2 copies of data (replica 2) seems pretty reasonable
similar to RAID 1 and still in the worst case the data can be
replicated after a fail. I see that replica 3 helps more on
performance at the cost of space.</p>

<p class="MsoNormal"><span lang="EN-US">my oVirt-Setup is 3
Hosts with gluster and reaplica 3. I always try to stay on
the current version and I’m applying updates/upgrade if
there are any. For this I put a host in maintenance and also
use the “Stop Gluster Service” checkbox. After it’s done
updating I’ll set it back to active and wait until the
engine sees all bricks again and then I’ll go for the next
host. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This worked fine for me
the last month and now that I have more and more VMs running
the changes that are written to the gluster volume while a
host is in maintenance become a lot more and it takes pretty
long for the healing to complete. What I don’t understand is
that I don’t really see a lot of network usage in the GUI
during that time and it feels quiet slow. The Network for
the gluster is a 10G and I’m quiet happy with the
performance of it, it’s just the healing that takes long. I
noticed that because I couldn’t update the third host
because of unsynced gluster volumes.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is there any limiting
variable that slows down traffic during healing that needs
to be configured ? Or should I maybe change my updating
process somehow to avoid having so many changes in queue? <o:p></o:p></span></p>
