[Gluster-users] Gluster volume heal info healed shows the healed entries under wrong brick

Hello Gluster developer
I have a gluster cluster with 2 nodes configured as replicated volumes, 
each node has one brick.

I did single node failure test including killing all gluster processes and 
power off one node. 

The node failed is node_f and the other node is node_h. During the 
node_f's failure period, I updated a file 'testMay24' (from a client 
machine other than the 2 nodes). I checked the file update is correct 
consumed on the healthy node/brick node_h. 

Then I started the processes OR power on the failure node node_f. After 
that I found the file updated during the node_f failure was healed on 
node_f (with the updated content).

I checked the self-healing information by using 'gluster volume heal 
volume_name info healed'. I found that the healed entries are all listed 
under the node_h, which I supposed should be listed under node_f. Also the 
old healed entries on node_f previous to my test was lost. There are no 
entries that needs heal and no entries of split-brain.

I guess this is related to the self-heal daemon's restart on node_f. Is 
this designed like this or my misunderstanding or a bug? Thanks in advance 
for your help!

during the node_f's failure time. I supposed it should be listed under

but were lost after test.
