Linux Server Failing Gracefully with Systemd OnFailure

Episode 109 of Linux Server Admin with Fexingo dives into a powerful but often overlooked systemd feature: OnFailure=, which automatically triggers a rescue unit when a critical service fails. Lucas and Luna walk through a real-world scenario — a database server that needs to page the admin and attempt a safe restart without manual intervention. They cover how to pair OnFailure with a custom target, a notification script via mailx, and a delayed restart timer to avoid restart loops. The episode also touches on cgroup resource limits and journald log persistence to make auto-recovery truly robust. If you've ever woken up to a dead service at 3 AM, this one's for you. #LinuxServerAdmin #Systemd #OnFailure #ServiceFailure #AutoRecovery #SysadminTools #BashScripts #ServerResilience #DbFailover #Cgroups #Journald #MailxNotifications #TimerUnits #TechPodcast #FexingoBusiness #BusinessPodcast #ServerEngineering #HighAvailability Keep every episode free: buymeacoffee.com/fexingo
