Did you make any changes to filesystem or did anything that lead to corrupt files for ClickHouse?

This is the second time this has happened. After a sudden VM shutdown, Clickhouse corrupts.

Is it possible to reinstall the system from scratch, without losing users/passwords?

Yes, and if you can avoid this that would be great.

You can purge the ClickHouse data but retain the rest. delete the ClickHouse data under `deploy/docker/clickhouse-setup/data/clickhouse*`
