Controlled shutdown can fail if the cluster has non zero under replicated
partition count. Since that means the leaders may not move off of the
broker being shutdown, causing controlled shutdown to fail. The backoff
might help if the under replication is just temporary due to a spike in
traffic. This is the most common reason it might fail besides bugs. But you
can check the logs to see why the shutdown failed.
