EX2 frozen in "Change raid mode" formatting at 0%

I chose raid 1 (on all of the drive) and encryption. The system has now been frozen for almost ten hours at this text

Change RAID Mode 

Be patient as the WD My Cloud EX2 device formats your volume.



I restarted it one but it hapened the same thing next time I made the same settings.

I can’t access the drive or anything, so it seems to be frozen or be doing something. I know a 8TB formatting can take ages, but should I really be getting no confirmation that something is happening? Do I just have to wait 24 hours more or so to tell if it is (was) really formatting or has just frozen?

Anyone who has encountered a similar problem? Solution?

Hi Qwertus, is the RAID still rebuilding?
