Fedora 27 – MariaDB (mysql) #mysql50#.rocksdb errors

Recently I started encountering ” #mysql50#.rocksdb” errors with mysql. To solve this I stopped mariadb: systemctl stop mariadb edited /etc/my.cnf.d/rocksdb to comment out the plugin and added ignore-db-dirs=.rocksdb to /etc/my.cnf, then restarted mariadb systemctl start mariadb Now I can backup or query the database properly.
