I think triaging to gnome-shell-extensions might be the wrong approach in this case.
The icons did appear before and do appear in other installations. It is just on this machine that after enabling ubuntu-dock they do not appear any more (I do not want to verify this behaviour on any other machines as the missing icon leads to dirty unmounts)
There must be a setting somewhere to enable disks again. There used to be a setting in gnome-tweak-tools (but was left out in gnome-tweaks). Also there was a setting in gsettings / dconf which is gone as well.
So the question is: Where does UBUNTU (and not Gnome) store its setting about how to deal with mounted devices?
