I can only suggest do not do like that. (ССЗБ :)
In your configuration you mixes several types of labels,
and you do not use hardcoded providers names. In your case when GMIRROR
does tasting it can take one of three providers which his metadata for
each mirror (e.g. partition, ufs/label, ufsid/id).

So, I see several ways to get what you want:
1. Use gmirror for the whole disk
2. Use hardcoded providers names
3. Disable ufs and ufsid labels via loader.conf.

Similar problem described in kern/150555.
