Thank you Rahul for the report. This does help to keep community up to date
on the effort being put up here and understand where the things stand. Some

https://github.com/gluster/glusterd2/issues/739 which is being worked on
and that should help us to achieve this backward compatibility.

We need to move towards parsing error codes than the error messages. I'm
aware that with GD1/CLI such infra was missing, but now that GD2 offers
specific error codes, all command failures need to be parsed through
error/ret codes in GD2. I believe the library/tests need to be modified
accordingly to cater to this need to handle both GD1/GD2 based failures.
