Problem

With the manually fixes of Romain/Ops to reattach a volume back to the ABM cluster, it could be that a namespace is reattached with a wrong preset or a preset that doesn't exists.

for example:

Not sure if the gui should not load if a namespace have a wrong preset name. Maybe just throw an error on the gui instead of an empty page.

Quite difficult to propagate serializer exceptions back to the GUI. We catch and log exceptions when we can anticipate them. Fiddling around with some metadata in Alba is not something we expect though.

Closing this one down as result of manual incorrect steps.
