Not sure why ^^ occurs. You could try flushing iptables (iptables -F), 
restart glusterd and run the heal info command again .

Sorry  I meant 'gluster volume heal c_glusterfs info' should give you 
the files that need heal and 'gluster volume heal c_glusterfs info 
split-brain' the list of files in split-brain.
The commands are detailed in 
https://github.com/gluster/glusterfs-specs/blob/master/done/Features/heal-info-and-split-brain-resolution.md
