Network Partitioning Figure 18.14 Forcing a New Membership Suppose that you are back in the situation where s1 and s2 are the only servers left in the group. Servers s3, s4 and s5 have left the group unexpectedly. To make servers s1 and s2 continue, you want to force a membership configuration that contains only s1 and s2. This procedure uses  group_replication_force_members  and should be considered a last resort remedy. It  must  be used with extreme care and only for overriding loss of quorum. If misused, it could create an artificial split-brain scenario or block the entire system altogether. Warning 3755
