    Description

      Steps to reproduce

      1. Created a 4 node kv cluster 172.23.121.194, 172.23.121.203, 172.23.121.160, 172.23.121.199
      2. Created an ephemeral bucket named 'default' with replicas=3 and loaded some docs onto it
      3. Disabled auto-failover
      4. Enabled auto-reprovision
      5. Induced a failure "restart_machine" in node 172.23.121.194
      6. A few minutes later, added node 172.23.121.198
      7. Started a rebalance

      Rebalance fails with

      The issue is not very consistent, cannot comment if this is a regression.
