Unfortunately, I lost my Ansible playbook collection that set high availability for MySQL, or MariaDB, and NFSd on Debian Linux. It's frustrating, but I'll have to rewrite it. However, I believe I can type the commands faster than writing the playbooks again. On the bright side, it's possible that the playbook collection still exists on my second backup hard disk, which I keep in another city. Either way, I'll be able to complete the task quickly by typing commands. #fml #sysadmin #linux #debian
