Like mdmonitor but for btrfs filesystems. Get an email whenever an error is detected.
You need to have a smtp-forwarder installed and properly configured to use this tool.
I recommend Nullmailer as it is pretty easy to configure.
The main config file is located at /etc/conf.d/btrfs-monitor. Use this to specify the destination email address for status messages.
This application uses systemd timers to perform hourly checks on specified mount points.
These mount points are specified in the command to enable the timer, exactly like how btrfs-scrub@.timer works.
To get your systemd escaped path simply use the below command:
systemd-escape -p /path/to/mountpoint
And then enable the timer with:
systemctl enable --now btrfs-monitor@previous-command-output.timer
- Add more status sources and more verbose messages
