How to set threshold for data filesystem (md0)

omvbonn · Dec 4th 2025

Hi !

Within the list of monit environment variables I cannot find a threshold for the data filesystem (md0) filesystem.

Code

# omv-env list | grep -iE '.*MONIT.*FILESYSTEM.*'
OMV_MONIT_SERVICE_FILESYSTEM_ROOT_USAGEWARNTHRESHOLD

Is the any possibility to set different thresholds for each filesystem ?

Greetings

You can set the warning threshold in the Storage -> Filesystems tab. Just select the filesystem and click the Edit button.

Thanks.

In previous releases exists a OMV_MONIT_SERVICE_FILESYSTEM_ROOT_USAGEWARNTHRESHOLD variable.

Is the any possibility to modify the thresholds for each filesystem without using die WebGUI ? Just in case.

That variable still exists but as the title mentions, it only applies to the root (OS) filesystem.
