Subject Re: observer changing to participant when there is no quorum
Date Tue, 14 Jun 2016 21:35:56 GMT
This is needed only in case the target config doesn't have a quorum which
are already followers in the old config
and are up. We need agreement from a quorum of the target config, but
observers aren't participating
in the voting protocol.
