Galera Cluster expire_logs_days
Is it safe to modify the "expire_logs_days" variable while the cluster is running? show variables like 'expire_log_days' is 14, I've not defined this under my.cnf or wsrep.cnf.
What would be the proper procedure to reduce or increase binlog expiry?

It is completely safe to modify this variable when the cluster is running; e.g : SET GLOBAL expire_logs_days=7;
