    XMLWordPrintable

Details

    Description

      Build : 5.5.0-2884
      Test : GSI component test : -test tests/2i/test_idx_rebalance_replica_vulcan_kv_opt.yml -scope tests/2i/scope_idx_rebalance_replica_vulcan.yml
      Scale : 3
      Iteration : 3rd iteration (~20 hrs of run)

      In the 3rd iteration, the step in the test to rebalance out a KV node fails when memcached crashes on the master node. The rebalance operation after that is stuck with indexer nodes not completing rebalance. Index building is stuck on all indexer nodes. The following messages can be seen in the indexer logs:
