You will first need to restore connectivity between the gluster peers
for heal to work. So restart glusterd on all hosts as Strahil
mentioned, and check if "gluster peer status" returns the other nodes
as connected. If not, please check the glusterd log to see what's
causing the issue. Share the logs if we need to look at it, along with
the version info
