I am stuck with failure of my gluster 2x replica heal with messages at 
glustershd.log as :

*[2018-11-21 05:28:07.813003] E [MSGID: 114031] 
[client-rpc-fops.c:1646:client3_3_entrylk_cbk] 0-gv1-client-0: remote 
operation failed [Transport endpoint is not connected]*

When the log hits here In either of the replica nodes; I can see that my 
command: *watch glsuter volume heal <my volume> statistics *returns no 
more progress and status unchanged afterward. I am running glusterfs on 
top of zfs and it is basically a storage for small read-only files. 
There was a thread with Shyam Ranganathan and Reiner Keller in here 
where the core of the problem was the storage going out of inods and no 
space left error which obviously can not be my case as am on top of ZFS. 
However, the similarity between us is that we were previously on 3.10 
and upon various issues with that version we upgraded to 3.12 on Ubuntu 
16.04 with kernel 4.4.0-116-generic.

Anybody faced issue as above?Can you advise what can be done as it is 
for over a month with no effective self-heal process completed...

Here is my gluster cluster info:
