Details

    Description

      Build: 7.1.0-1787

      Scenario:

      • 7 node cluster
      • Couchbase bucket with replicas=3
      • Set auto-failover with max_events=1 and timeout=5
      • Stop memcached on 2 nodes  (172.23.100.13 and 172.23.100.14)

      Observation:

      Seeing auto-failover is getting triggered and fails with the following reason and getting retied continuously.

      Could not auto-failover more nodes (['ns_1@172.23.100.14']). Maximum number of auto-failover events (1) has been reached

      Expected behavior:

      Auto-failover should never get attempted if the max_events configured is less than the failed nodes in cluster.
