I can see that too with os-prober installed.

  $ sudo update-grub

I see processes such as:
"grub-mount /dev/mapper/vg1-SomeLogicalVolume /var/lib/os-prober/mount"

(Note that this LV has nothing to do with the boot process: it is not
mounted, and hosts no part of the system).

Without os-prober installed:
