The webui currently does not automatically notify the user when a disk is added or removed. This can lead to awkward situations and is not a good user experience.
The webui should implement such notifications in a persisten top level component like app.component or topbar. The notification should ideally be in the form of a snackbar.
However, since we don't currently have snackbars in the UI and if we decide against introducing a new component, we could alternatively use a modal dialog instead.
