Got error 168 - 'Unknown (generic) error from engine' from storage engine
Storage engine can't drop table 'admin.open_api_url'
实际上open_api_url.ibd 文件存在的
Actually, open_api_url.ibd file exists
root@lot-server:/var/lib/mysql/admin# ll open_api_url.ibd

3.
Except for desc open_api_url statement, execute open_api_url All SQL statements related : Tablespace is missing for table admin/open_api_url.
How to repeat:
1.executing the TRUNCATE SQL statement
Suggested fix:
I guess it should be related to tablespaces, so I suggest improving tablespace design
