Francesco Nigro updated ARTEMIS-3703:
-------------------------------------
Description:
With pluggable quorum vote, if the backup connection drop, live can serve
clients unreplicated while not yet incremented activation sequence: this can
lead to inconsistency if the unreplicated live will crash *before* it, causing
the replica to be able to become live, but with some missing data.
was:
With pluggable quorum vote, if the backup connection drop, live can serve
clients unreplicated while not yet incremented activation sequence: this can
lead to inconsistency if the unreplicated live will crash *before* it.
A backup with that same activation sequence can start and become live even if
the just crashed live data is different.
> Block clients until coordinated sequence is advanced after backup drop
