Find the data and log locations: SELECT VARIABLE_NAME, VARIABLE_VALUE FROM performance_schema.global_variables WHERE (VARIABLE_NAME LIKE '%dir' OR VARIABLE_NAME LIKE '%file') AND VARIABLE_NAME NOT LIKE '%core%'; then run df -h <directory> for datadir and the others. They must not be on the root (/), /var or /usr partitions.

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

Create a dedicated partition/volume for the data, stop MySQL, move datadir there (copy preserving ownership mysql:mysql), update datadir in /etc/my.cnf (or /etc/mysql/mysql.conf.d/mysqld.cnf) and any SELinux/AppArmor policy, then start MySQL.
