I detached a drive from a mirror... how do I attach it back?

[leomanes]

Hi all, I can't find anything on Truenas manuals or online about re-attaching drives.

I detached one of the drives on my mirror and now I can't attach it back. The pool is there and everything is working fine but the mirror is apparently gone, it's just a single drive with a Pool in it now.

There was nothing wrong with the mirror I was just tinkering with the server... but don't worry, it is a lab server...
If it is important, there are(were) only two drives on the mirror.

Any ideas?

Thank you guys

Please post the output of zpool status <your pool> and gpart list <the detached drive>.
