    XMLWordPrintable

Details

    Description

      Steps to reproduce

      1. Created a 3 node cluster on k8s with operator with all services
      2. On one pod, memcached was killed in a loop. Multiple failovers and rebalance failures occur as expected
      3. Stopped the memcached kill loop.
      4. Rebalances beyond this fail in a loop(as triggered by the operator again and again) - tracked in MB-62724.
      5. Rebalance fails with leader_activities_error.
      6. Cluster status suddenly changes from unbalanced to balanced post this failure

      Rebalance exited with reason {{badmatch,
      {leader_activities_error,
      {default,rebalance},
      {quorum_lost,
      {lease_lost,
      'ns_1@cb-example-0001.cb-example.default.svc'}}}},
      [{ns_rebalancer,rebalance,7,
      [{file,"src/ns_rebalancer.erl"},{line,456}]},
      {proc_lib,init_p_do_apply,3,
      [{file,"proc_lib.erl"},{line,240}]}]}.
      Rebalance Operation Id = 275e6c370d3c4bac4f45fe2fc175764b
