[Gluster-users] Files not healing & missing their extended attributes - Help!

Hi,
>From the logs you have pasted it looks like those files are in GFID
split-brain.
They should have the GFIDs assigned on both the data bricks but they will
be different.
Can you please paste the getfattr output of those files and their parent
from all the bricks again?
Which version of gluster you are using?
If you are using a version higher than or equal to 3.12 gfid split brains
can be resolved using the methods (except method 4)
explained in the "Resolution of split-brain using gluster CLI" section in
[1].
Also note that for gfid split-brain resolution using CLI you have to pass
the name of the file as argument and not the GFID.
If it is lower than 3.12 (Please consider upgrading them since they are
EOL) you have to resolve it manually as explained in [2]

Thanks & Regards,
