Hi All,
Below are the proposed protocol changes (ie, XDR changes on the wire) we
are thinking for Gluster 4.0.
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.
Poornima/Ram,
Please add if I missed out anything.
Thanks,
Soumya
