Mirroring existing 1-SSD pool with slightly smaller drive

Thanks. I just went to do this, and it turns out I can’t create a new VDEV. I get the following error:

[EFAULT] Failed to wipe disk ada1: [Errno 1] Operation not permitted: '/dev/ada1'

After no small amount of Binging, I ran sysctl kern.geom.debugflags=16 from root and tried to create the new VDEV again. Now it gives me a different error:

[EFAULT] Unable to GPT format the disk "ada1": gpart: geom 'ada1': File exists

middlewared.service_exception.CallError: [EFAULT] Unable to GPT format the disk "ada1": gpart: geom 'ada1': File exists

I then proceeded to run dd if=/dev/zero bs=1M count=100 of=/dev/ada1 and then try to create a VDEV with ada1. I got the same error as above.

I have no idea how to proceed from here.
