| 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:
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. |

I've added the following section to the documentation: I'm not entirely sure if this is the proper way to disable encryption of the redo log. marko or jplindst might know better. |
