No disk space usage charts for some disks / mountpoints

I do not see disk space usage metric for some disks - neither from the proc.plugin nor from the diskspace.plugin.

Specifically, I would like to see used disk space for /mnt/scratch which is the mountpoint for /dev/mapper/vgroot-lv1.
Here is the exact mountpoint info:

cat /proc/self/mountinfo
1299 1066 253:0 / /mnt/scratch rw,relatime master:53 - ext4 /dev/mapper/vgroot-lv1 rw

In the dashboard, I see charts from proc.plugin for disk vgroot-lv1 (for example disk.vgroot_lv1, disk_ops.vgroot_lv1, …), but there are no charts for free and used disk space.

I also see various charts from diskspace.plugin for /dev, /run, /tmp, etc., but none for the mountpoint /mnt/scratch.

This is using stock configuration, not overrides.

I have also tried adding the following to /etc/netdata/netdata.conf, but it has no effect on the dashboard:

	space usage = yes

	enable = yes
	utilization percentage = yes

Here is some more info about the system:

Hi @jakob_leben ! Welcome !

There have been some recent changes there, is it possible perhaps to try the latest (1.36.1) version, and we could pick it up from there if the problem persists? Thanks!
