The Ultimate Guide to High Availability with MariaDB

Unknown global parameter 'substitute_variables'.

I updated MaxScale to 2.3.2 and now I get the following errors:

===> Starting Application

2019-01-25 13:59:53   error  : Failed to parse configuration file /etc/maxscale.cnf. Error on line 2.

It looks like the 'substitute_variables' parameter is not supported anymore?

The same config file worked with 2.2.19

Answer Answered by Johan Wikman in this comment.

There has been a regression, the parameter should be supported.
