/mnt is the mount point. I now did the following

dd if=/dev/zero of=/dev/sdd

Finally, btrfs does not recognize the partition as part of my raid
anymore, but what's worse is that it now tells me that two missing
devices is a no go, so I cannot mount it as anything but read-only. All
the data is there, /dev/sdd1 was never used and /dev/sdd was the
originally missing one. Mounting as read-only prevents you from adding
devices.

I guess I have to start over... At least the old pool is still readable.
Sucks that I have to rebuild it though. I guess there is no way to keep
my snapshots without having them fill their full size.
