I have shot myself in the foot just now. My daily machine is running 12.0 on a zfs pool that has just one disk. It originally was used to install 11.1 and the installer partitioned the drive such that the zpool is on /dev/ada0p3. I chose 'zfs on root' during the install. Not sure about p1 but p2 is swap.
I picked up a couple SSDs to add to the mirror with one being a spare. To test I added one of them with
zpool add zroot /dev/ada1
and it added the entire disk, listing it as /dev/ada1, unlike /dev/ada0p3, the other half of the vdev. From the web it appears I cannot pull ada1 out of the mirror, and detach does indeed do nothing. What might a fix here? I can silver ada1, plug it in as ada0, and then add the old ada0 to the mirror. I'm really just fearing borking the original install setup and that p1-2-3 partition arrangement. I really don't want to reinstall.
