IIRC I had the problem that 'gmirror insert' without '-h' not always
inserted the slice specified by the entire block device (e.g. /dev/ad4s1
vs. /dev/ad4). Apparently there is some auto detection code and/or
gmirror cannot differ correctly, but that's just a guess. Specifing '-h'
fixed it in my case.

If I understand you correctly moving swap to a different slice should do
the job.
