    Description

      Steps to reproduce

      • Install Couchbase server 5.0.0 on 3 centos 7.6 servers and create cluster with services of each node (kv,index-kv,n1ql -kv,fts).
      • Create default bucket and load data to default bucket.
      • Graceful failover 1st node and upgrade node from 5.0.0 to 6.5.0-4908 (use rpm -U cbserver.rpm)
      • Set full recovery and rebalance. Rebalance success as expected.
      • Graceful failover 2nd node and upgrade node from 5.0.0 to 6.5.0-4908 (use rpm -U cbserver.rpm)
      • Set full recovery and rebalance. Rebalance success as expected.
      • Graceful failover 3rd node (last 5.0.0 one with ip 224) and upgrade node from 5.0.0 to 6.5.0-4908 (use rpm -U cbserver.rpm)
      • Set full recovery and rebalance. Rebalance failed instantly with error " 'memcached' exited with status 134."
      • Rebalance again, rebalance success
