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>
