Neo4j-admin unbind is not working

Hi admin,

I used helm chart to install neo4j 4.0.4 enterprise version
https://neo4j.com/docs/operations-manual/current/tutorial/import-tool/

We are planning to import data to causal cluster.
By referring to doc here https://neo4j.com/docs/operations-manual/current/clustering/seed/#causal-clustering-seed-import

it mentioned "neo4j-admin unbind" should be fired.
After the command was executed, there is an error. However, the neo4j server was not running and the "neo4j" database was stopped.

root@c6-neo4j-core-0:/var/lib/neo4j# ./bin/neo4j-admin unbind
Database is currently locked. Please shutdown database.

root@c6-neo4j-core-0:/var/lib/neo4j# ./bin/neo4j stop
Neo4j not running

neo4j@system> show databases;
