Mysqldump: Got error: 1017: Can't find file: when using LOCK TABLES

Ошибка:

# mysqldump db_name > db_name .sql
mysqldump: Got error: 1017: Can't find file: 'tb_name_game' (errno: 2) when using LOCK TABLES

решение - попробовать с опцией - --lock-tables=false

mysqldump --lock-tables=false db_name > db_name .sql

или с --skip-add-locks:

 mysqldump --skip-add-locks db_name > db_name .sql
