I tried reactivating them the invalid, missing disks, volumes. I tried bringing the invalid offline and back online from GUI and diskpart. Nothing helped. I have a few week old backup of the disk, I'm not worried about the data. But this was only a simple volume, and I have other Dynamic Disks in my system with mirrors on them and I don't want this or similar things happenning to them. So why is this happening?
