Client1 believes hello.c is something different to what Client2 believes. Which client will responsibly reconstruct the data? Will the journaling of the remaining servers be used to reconstruct the data on the new server?
'changes' are done in sync on both server1 and server2 always
(writes()s are sent to all child nodes). when server3 comes in place
of server1, the self-heal should detect that hello.c is missing on
server3 and sync it from server2.
