The usage warning threshold for rootfs is ignored in OMV 6

I'm getting this e-mail notification:

Service:     rootfs
Event:       Resource limit matched
Description: space usage 85.5% matches resource limit [space usage > 85.0%]

I'd like to update the usage warning threshold of rootfs to 90 or 95% in OMV 6.

I see that old OMV_MONIT_SERVICE_FILESYSTEM_SPACEUSAGE=95 in /etc/default/openmediavault trick no longer works in OMV 6. We're now given the option to set a per file system usage warning threshold. Nice!

To expose that threshold for rootfs, one needs to install the sharerootfs plug-in. Done.

One problem, though. If I set a threshold for rootfs to 95%, and run:

omv-salt stage run prepare
omv-salt deploy run monit

I still get the e-mail notification.

I expected /etc/monit/conf.d/openmediavault-filesystem.conf to be updated to 95%, but it still seems to contain:

# Alert if disk space of root filesystem gets low
check filesystem rootfs with path /
    if space usage > 85% for 5 times within 15 cycles
        then alert else if succeeded for 10 cycles then alert

Am I doing something wrong?

You need to use the env variable OMV_MONIT_SERVICE_FILESYSTEM_ROOT_USAGEWARNTHRESHOLD

Thank you. I'll give that variable a try and remove the sharerootfs plugin if it works as expected.
