Hi Kasturi,
Ill try that. Will this be persistent over a reboot of a host or even
stopping of the complete cluster ?
Thank you
Hi Sven,
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.
Thanks
kasturi.

Hi All,
my oVirt-Setup is 3 Hosts with gluster and reaplica 3. I always
try to stay on the current version and Im applying
updates/upgrade if there are any. For this I put a host in
maintenance and also use the Stop Gluster Service checkbox.
After its done updating Ill set it back to active and wait until
the engine sees all bricks again and then Ill go for the next host.
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 dont
understand is that I dont 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 Im quiet happy with the performance of
it, its just the healing that takes long. I noticed that because
I couldnt update the third host because of unsynced gluster volumes.
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?
Thank you,
Sven

Hi Sven,
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.
You can run|gluster volume set|/VOLNAME/|cluster.granular-entry-heal
enable / disable|command only if the volume is in|Created|state. If
the volume is in any other state other than|Created|, for
example,|Started|,|Stopped|, and so on, execute|gluster volume heal
VOLNAME granular-entry-heal||enable / disable|command to enable or
disable granular-entry-heal option.
Thanks
kasturi
