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

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.
