Still getting to learn this so I apologize if this is an easy question. How can I make sure none of my SQL nodes are running in bootstrap mode? I ran a service mysql status on all 3 nodes in percona cluster 5.7 and they all show mysql.service - Percona XtraDB Cluster and active. Not sure how else to check. I need to reboot all the nodes 1 at a time but was wanting to verify none were in bootstrap mode.
