I had two SSDs setup as mirrored metadata vdev on a pool, and one disappeared.... looked "disconnected" in the webui, and I offlined it. Oopsie, now I'm down to a single drive in my special vdev, and I want to fix that.
Two options --
1) Can I add the second drive as a mirror to the existing special vdev? If so, how would I go about this (assuming CLI)?
2) Would it be safer/better to offline/disconnect the current, single disk in the special vdev, and then re-attach as a mirror? Some google said this could cause issues on the pool, but want to make sure.
Any other option here? I've tried adding two new drives in a mirror into the special vdev, but this resulted in an error (i.e., couldn't have a stripe and mirror vdev in special)
