BUG REPORT

Feature request to disallow dropping replication factor to 1 in multi-node cluster is here: #27026

Logs to be provided. Reported by user leonardo on the forum: https://forum.cockroachlabs.com/t/node-decommissioned-but-2-ranges-are-broken-unavailable/1786

2. Please describe the issue you observed:

• What did you do?
  In a 6 node cluster, reduced replication factor to 1 and decommissioned node. Node reported decommissioning complete, but two ranges are still leased to the node.

• What did you expect to see?
  No ranges leased to node, stopping the node has no impact on data availability.

• What did you see instead?
  Stopping the node results in unavailable ranges.
