Hi,
with OMV 2 I was using 4HDDs with mergerfs to store my data and access it via samba share. After upgrading to OMV 3 something went totally wrong and i can not access my share (sorry if the Menus are not named correctly, but I am using german language)). Under "Union-Filesystem" everything is as expected, 4 HDDs combined unter the name "Data".
In "Filesystem" the drive "data has the same size like the system drive.
Output of: omv-showkey unionfilesystems

Hopefully someone has an idea
