--- Comment #1 from Anoop C S <anoopcs at redhat.com> ---
I think I failed to handle the scenario where clients are upgraded before

RCA:(new clients[>=4.0] and old servers[<=3.13])
SETVOLUME request from client post-upgrade does not contain its lk-version in
dictionary that is being passed onto
server(https://review.gluster.org/#/c/12363/). This means that the server side
check for "clnt-lk-version" inside the received dictionary would fail and error
is returned back to new client.
