Thanks, noted. One more query. Are there files inside each of these
directories? Or is it just empty directories?
You will find below the content of each of these 3 directories taken the brick on node 1:
i)/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10
drwxr-xr-x 4 www-data www-data 4 Nov 5 14:19 .
drwxr-xr-x 31 www-data www-data 31 Nov 5 14:23 ..

drwxr-xr-x 3 www-data www-data 3 Nov 5 14:19 .
drwxr-xr-x 4 www-data www-data 4 Nov 5 14:19 ..
drwxr-xr-x 2 www-data www-data 4 Nov 5 14:19 oc_dir

drwxr-xr-x 2 www-data www-data 4 Nov 5 14:19 .
drwxr-xr-x 3 www-data www-data 3 Nov 5 14:19 ..
-rw-r--r-- 2 www-data www-data 32 Nov 5 14:19 fileKey
-rw-r--r-- 2 www-data www-data 512 Nov 5 14:19 username.shareKey
so as you see from the output above only the "oc_dir" directory has two files inside.
Okay, I'm assuming the list of files+dirs are the same on nodes 2 and 3
as well. Correct me if that isn't the case.
symlinks are only for dirs. For files, they would be hard links to the
actual files. So if stat
../brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf gives you
a file, then you can use find -samefile to get the other hardlinks like so:
#cd /brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf
#find /brick -samefile aae4098a-1a71-4155-9cc9-e564b89957cf
If it is a hardlink, then you can do a getfattr on
/brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf itself.

Thank you for explaining this important part. So yes with your help I could find the filenames associated to these 2 GFIDs and guess what? they are the 2 files which listed in the output above of the "oc_dir" directory. Have a look at this:
# find /data/myvol-pro/brick -samefile aae4098a-1a71-4155-9cc9-e564b89957cf
/data/myvol-pro/brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf
/data/myvol-pro/brick/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir/fileKey
# find /data/myvol-pro/brick -samefile 3c92459b-8fa1-4669-9a3d-b38b8d41c360
/data/myvol-pro/brick/.glusterfs/3c/92/3c92459b-8fa1-4669-9a3d-b38b8d41c360
/data/myvol-pro/brick/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir/username.shareKey
Okay, as asked in the previous mail, please share the getfattr output
from all bricks for these 2 files. I think once we have this, we can try
either 'adjusting' the the gfid and symlinks on node 2 for dir11 and
oc_dir or see if we can set afr xattrs on dir10 for self-heal to purge
everything under it on node 2 and recreate it using the other 2 nodes.

I hope that helps the debug further else let me know if you need anything else.
