    Description

      A month ago the Mariadb server and client worked perfectly with phpMyAdmin, but since I reinstalled the entire system I have appeared in the SSH console:

      /opt/bin/mysql_install_db --user=admin --basedir=/opt --datadir=/opt/var/mysql/ --lc-messages-dir=/opt/share/mariadb

      OK

      Impossible to start the server with the command:

      /opt/etc/init.d/S70mysqld start

      Is it possible to deactivate the MADV_DODUMP function ?. The "-core-file" and "-innodb-buffer-pool-in-core-file" commands do not exist in this system Linux.

      I have a previous backup and this does not happen.

            I've tried these settings and it doesn't change anything:

            [mysqld]
            innodb_buffer_pool_size=8G
            core-file
            core-nodump=NONE

            [mysqld]
            innodb_buffer_pool_size=8G
            core-file
            core-nodump=INNODB_BUFFER_POOL

            The kernel of the Asus-Merlin firmware is 4.1.51. The installation of MariaDB through Entware worked after (opkg list | grep mariadb | awk '

            {print $ 1}

            ' | xargs opkg install)

            The problem appears when updating from 10.2.26 to 10.4.10

            I do not think that the warning message should prevent the server from starting up or shutting down.

            I see 3 messages for both types of calls, corresponding to the 3 data structures being allocated via those interfaces. Which kernel version are you using? A Linux kernel bug fix related to the calls and huge pages was mentioned in MDEV-10814.
