disk in GUI shows up that the OS does not know

[nielsk]

The GUI shows me a disk da1 as unknown and unavailable
When I do in the shell a camcontrol devlist there is no da1.
In /var/log/middlewared.log I find the following entry (line breaks for readability)

Code:

/var/log/middlewared.log:[2021/04/13 10:12:10] (INFO) DiskService.sync_all():94 - Found disks:

'ada0': {'name': 'ada0', 'ident': 'XXXXXXX', 'lunid': '5002538e90643fab', 'serial': 'XXXXXXX'}}

Is that a known bug or what can I do that da1 gets out of the GUI? It is even offered as a member disk, when I want to replace it
