[Lustre-devel] [RFC] HLD Review Request: Interoperability at server side
Really good - well done! I feel comfortable that this can move ahead. I just want to ask you to make sure that repeated upgrade - downgrade - upgrade events (in the case bugs in the new release force the user back to old) are handled correctly. I did see a discussion of up and down, but no explicit mention of repeating that process multiple times.

This has been discussed, and the agreement was that some fixes (bug 15993) are needed in 1.8 server, so that it removes any remaining 2.0 state during downgrade. > > Regards, > > Peter > Nikita.
