Poornima and I were discussing if we can include volume uuid as part of 
Handshake protocol between protocol/client and protocol/server so that 
clients do not re-connect if the volume was deleted and recreated with 
the same name, eliminating potential issues at upper layers [1].

We haven't looked into details, but the idea is to have glusterd2 send 
volume uuid as part of GETSPEC request to clients & brick processes 
which shall be used by protocol/client & protocol/server (may be along 
with vol name as well) during HNDSK_SETVOLUME.


Please add if I missed out anything.
