I think for some reason setting of AFR xattrs on the parent dir did

of getting recreated on repo2 using the files from repo0 or 1).
Can you provide the getfattr output of the parent dir of one of the
.meta files? Maybe
'/372501f5-062c-4790-afdb-dd7e761828ac/images/968daf61-6858-454a-9ed4-3d3db2ae1805'.
Please share it from all three bricks.
Also, after you brought repo2 back up, can you check the glustershd.log
of repo0 and repo1 to see if they contain entry-selfheal messages for
the directory, something like:
"[2020-01-27 08:53:47.456205] I [MSGID: 108026]
[afr-self-heal-common.c:1750:afr_log_selfheal] 0-engine-replicate-0:
Completed entry selfheal on <$gfid-of-directory>. sources=[0] 1
sinks=2"
The timestamps should be after repo2 came back online after the
upgrade.

Hi Ravi,
This is the third time an oVirt user (one is me and I think my email is in the list) that report such issue.
We need a through investigation as this is reoccurring.
Thanks to in-house testing by Milind and Satheesaran, we now know why
the parent directory did not have pending xattrs and why the files were
not getting healed. You can look at
https://bugzilla.redhat.com/show_bug.cgi?id=1801624 for more info. Once
the fix (https://review.gluster.org/#/c/glusterfs/+/24109/) is reviewed
and merged, I will back port it to the release branches.
Best Regards,
Strahil Nikolov
