Galera cluster: change the size of InnoDB Redo log files online?

Question

We have a 3 node Galera cluster. I need to change the mysqld innodb_log_file_size parameter (see Changing the Number or Size of InnoDB Redo Log Files).

I do this by stopping all 3 nodes and disabling Puppet. Can I do this change online with Galera? How?

Answer 1

The InnoDB redo log files are independent of galera. Because of this, you should be able to change the redo log configuration by doing a rolling restart and following the procedure in the link you referenced.
