1. Thank you for reaching my post and replied this.

2. Power-off all nodes except the highest SQNO one.
3. Execute command: systemctl mysql@bootstrap.service on the said highest SQNO node.
4. Wait...and cross your fingers, until the MySQL service on the bootstrap node is up.
5. Power-on the rest nodes "one at a time" and keep eyes on the cluster sync status. By execute command: clustercheck and cat /var/lib/mysql/grastate.dat to check the GALERA saved state information, etc.

\*\*\* My steps above may wrong or not practical same as when the Linux experts investigate the same issue, but this is what I found and it works for my case. 🙂 \*\*\*

Thank you
