[Lustre-devel] [RFC] HLD Review Request: Interoperability at server side

[Peter Braam]

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.

Regards,

Peter

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.

I will update the HLD to include the details related to repeating the
