Also, I see in the notification drawer a message that says:

Storage domains with IDs [ed4d83f8-41a2-41bd-a0cd-6525d9649edb] could not
be synchronized. To synchronize them, please move them to maintenance and
then activate.

However, when I navigate to Compute > Data Centers > Default, the
Maintenance option is greyed out.  Activate in the button bar is also
greyed out, but it looks like an option in the r-click context menu
although selecting that shows "Error while executing action: Cannot
activate Storage. There is no active Host in the Data Center.".

I'm just stuck in an endless circle here.
