Hi Sven,<br>
��� <br>
��� This is a volume set option ((has nothing to do with reboot)and
it will be present on the volume until you reset it manually using
'gluster volume reset' command . You just need to execute 'gluster
volume heal <volname> granular-entry-heal enable' and this
will do the right thing for you. <br>
<br>
Thanks<br>
kasturi.<br>

<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. </span><o:p></o:p></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.</span><o:p></o:p></p>

<p>Hi Sven,<o:p></o:p></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.<o:p></o:p></p>
