Rabalance failure due to index service error while upgrading windows cluster from 6.6.2 to 7.0

    XMLWordPrintable

Details

    Description

      1. Create a 6.6.2 cluster on windows machines. Include all services in the cluster
      2. Create buckets and create secondary indexes. Drop and recreate atleast 1 index.
      3. Try to upgrade the cluster via graceful failover and readd of the nodes.

      While doing the readd after upgrading a node, the rebalance failed with following error.

       Rebalance exited with reason {service_rebalance_failed,index, {worker_died,{'EXIT',<0.1546.28>,{rebalance_failed, {service_error,<<"Index default.default_success already exists">>}}}}}.

      Attaching the logs from the cluster (1 of the data nodes is missing since the node had run out of disk space to collect logs. But this was much after the rebalance had failed.)

       

      Definition of default_success that caused the above failure:

       CREATE INDEX `default_success` on `default`(`result`) WHERE (`result` = "SUCCESS")
