Autoshutdown: how to detect scrubbing?

Spoor12B · Nov 5th 2025

I've configured autoshutdown to check for several IP addresses, uploads and HDD io over the (default) 401 KB/s.

However, during the scrubbing of my ZFS pool, the IO rates are way above the 401KB/s value, but both harddisks are skipped:

Is there a way to have autoshutdown detect scrubbing? I couldn't find a process with iotop so I guess a script is needed?

RE: Is there a way to see if balance or scrub is running.

you can see on webGUI: forum.openmediavault.org/wsc/index.php?attachment/41344/

Thanks for your reply raulfg3.

I know that I can see it in the gui just as from SSH with zpool status poolname. However, I'd like to know how I can configure autoshutdownplugin to detect this so the system won't be shutdown while a scrub is active. Thanks!
