<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">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>

<p>Hi Sven,</p>
<p>��� Do you have granular entry heal enabled on the volume? If no,
there is a feature called granular entry self-heal which should be
enabled with sharded volumes to get the benefits. So when a brick
goes down and say only 1 in those million entries is
created/deleted. Self-heal would be done for only that file it
won't crawl the entire directory.</p>
