this flag (0|1) can be configured via quorum.last_man_standing and when enabled, it allows expected_votes to be dynamically recalculated. Assuming an 8 nodes cluster, every node votes 1 (mandatory requirement for this feature). In the first event, 3 nodes are lost. The remaining partition of 5 is barely quorate. After a configurable timeout (quorum.last_man_standing_window, default 10sec) the quorate partition is allow to recalculate expected_votes based on the remaining nodes. This operation will bring expected_votes to 5 and quorum to 3. Repeating the above loop, in the next event, 2 more nodes are allowed to die. etc. etc. Reviewed-by: Steven Dake <sdake@redhat.com> Signed-off-by: Fabio M. Di Nitto <fdinitto@redhat.com> |
