Since there can be some leftovers:
2023.07.24 07:08:25.238066 [ 140 ] {} <Error> Application: Code: 219. DB::Exception: Cannot drop: filesystem error: in remove: Directory not empty ["/var/lib/clickhouse/data/system/"]. Probably database contain some detached tables or metadata leftovers from Ordinary engine. If you want to remove all data anyway, try to attach database back and drop it again with enabled force_remove_data_recursively_on_drop setting: Exception while trying to convert database system from Ordinary to Atomic. It may be in some intermediate state. You can finish conversion manually by moving the rest tables from system to .tmp_convert.system.9396432095832455195 (using RENAME TABLE) and executing DROP DATABASE system and RENAME DATABASE .tmp_convert.system.9396432095832455195 TO system.
