Details

    Description

      Build: 7.0.0-4502-enterprise

      Steps:

      • 4 node cluster all KV nodes (6.0.0-1693)
      • Load 50K docs into the couchbase bucket(replica=1)
      • Upgrade all nodes 7.0.0-4502 build in incremental manner

      Observation:

      Each upgraded 7.0.0-4502 node shows num_replica_item count as zero on UI

      But rest stats reports current replica_item_count value. (rest_bucket_stat.txt)

           "interestingStats": {
              "couch_docs_actual_disk_size": 11031190,

      Note: Marking this as regression since the same scenario works fine on 7.0.0 build 4476
