Document how to safely disable innodb_encrypt_log

    XMLWordPrintable

Details

    Description

      We should document how to safely disable innodb_encrypt_log. The documentation doesn't currently say:

      https://mariadb.com/kb/en/library/encrypting-data-for-innodb-xtradb/

      https://mariadb.com/kb/en/library/xtradbinnodb-server-system-variables/#innodb_encrypt_log

      I suspect that the process is similar to this one:

      https://dev.mysql.com/doc/refman/5.6/en/innodb-data-log-reconfiguration.html

      So it would be:

      1.) If innodb_fast_shutdown is set to 2, set innodb_fast_shutdown to 1:

      SET GLOBAL innodb_fast_shutdown = 1;

      https://mariadb.com/kb/en/library/xtradbinnodb-server-system-variables/#innodb_fast_shutdown

      2.) Stop the server.

      3.) Set innodb_encrypt_log=OFF in the configuration file.

      4.) Delete the existing redo logs.

      5.) Start the server.
