About the sync, you can find the paths via:
1. Mount
mount -t glusterfs -o aux-gfid-mount vm1:test /mnt/testvol
2. Find the path of files:
getfattr -n trusted.glusterfs.pathinfo -e text/mnt/testvol/.gfid/<GFID>
I bet it's the same file that causes me problems. Just verify the contents and you
will see that one of them is newer -> just rsync it to the bricks node01 & node03
and run 'gluster volume heal <volume> full.'
I did a cross-post to gluster-users just now.
You are right, the brick-files have a slightly different timestamp:

Contents (getfattr, md5) are still identical.
I am unsure about your suggested rsync, tho:
- node1 has file,
- node2 does not,
- node3 has file.
So I can rsync node1 to node2 and node3 or node3 to node1 and node2.
Sync to node1 and node3 cant be done as node2 does not have the file.
Can I do the rsync on a live, running Gluster?
