I split the mirror, that is all I did so far.
What I am trying to accomplish is revert back the 2 drives (which were in the mirror) to raw state.
How can I accomplish that?

Everything I try to says device is busy.

I want to start all over from raw devices (I am learning, data are backed up).

Thanks

UPDATE: SAMBA was holding on to it.
It is now destroyed by zfs.

How can revert them back to raw?
GPART cannot destroy them, it says device is busy.
 
Please give details for others. I would have suggested overwriting the metadata on the drive or partition.
 
Hi, yeah sorry about that, I haven't written down the exact syntax (bad habit, I keep reinventing the wheels). But here is an overview:
— Created a mirror with 2 drives.
— Exported them via Samba as a share for a NAS to send its backup via rsync.
— Found a problem that when I shut down FreeBSD, the NAS does not remember the share. So I have to mount it by hand. So I am trying to find another way to do that. So I needed to destroy the mirror.

I had to stop the Samba server first, otherwise the mirror will not be destroyed (error busy).

1. split the mirror
2. zpool destroy -f <mirrorname>
3. gpart delete -i <index) <geom> <--- used gpart list to see the index
4. gpart destroy -F geom

This worked.
(I am recording everything from now on)
