to repro :

start from a imbalanced cluster wehre there are 1024 active vbuckets and less than 1024 vbuckets , then shut down the node and then you can see that autofailover fails over the node

in RN: When you try to automatically failover a node, Couchbase Server
will not perform the failover if there are not enough
replica nodes in the cluster to support the failed node.
