[MariaDB discuss] mysqlcheck/mariadbcheck: consistency check before mysqldump

Dear mariadb experts, I would like to do this to verify my dbs (to detect hardware errors so that I can replay a backup timely): mysqlcheck -u root -pX --check --all-databases --extended Is it definitely read-only? Can I rely on the return code (0=success)? Or do I not need this because "mysqldump" does consistency checks? Many Thanks and Best Regards! Felix -- Felix Natter
