Dear all,

I create a replicated volume with 2 nodes.

And I make a directory and create a few files in it.

[/mnt/gluster] # mkdir dir1

[/mnt/gluster] # echo 123 >> dir1/a

[/mnt/gluster] # echo 123 >> dir1/b

[/mnt/gluster] # echo 123 >> dir1/c

Then I bring down node 2 and rename dir1 to dir2

[/mnt/gluster] # mv dir1 dir2

After bring back node 2, dir1 reappear

[/mnt/gluster] # ls -l

drwxr-x---    2 harry    harry      4096 Apr 16 11:30 dir1/

drwxr-x---    2 harry    harry      4096 Apr 16 11:30 dir2/

It surprised me. But it makes sense since dir1 is still on node 2.

When node 2 come back, dir1 is healed on another node.

However when I list both dir1 and dir2, the file list is empty.

[/mnt/gluster] # ls -l dir1

[/mnt/gluster] # ls -l dir2

[/mnt/gluster] #

It seems a bug to me.

What is the expected result of this case?

This is strange. The expected result is that node 2 must also contain only dir2. i.e. the self-heal must happen from node 1 to node 2 once the latter comes back online.
Are the files present in the backend bricks?
