have you tried to do an ls on them? They are automount units and will only mount once accessed.

Yes it is, it uses systemd mount units. You can check the systemd config files for these mount units using the context menu (right mouse button) of a node in the QluMan GUI's Enclosure view and select the entry "Preview config". In the displayed filesystem tree look for the *.mount files and select them. From their content you will be able to see the arguments of the corresponding mount command. On the net-booted node itself you can look into the systemd journal using 'journalctl -xe' and check what error (if any) you have when the mount is activated.
Best,
Roland
