It looks like you added the slice ada2p11 to zmisc, rather than the
mirror ada2p11 da2p8. If so, these commands could fix things:
# zpool remove zmisc ada2p11
# zpool add zmisc mirror ada2p11 da2p8
But, I am confused by your storage architecture. Why one internal "3
TB" drive and three external "2 TB" drives? What is the 2.0T internal
slice for? What are the three 1.7 GiB external slices for? What are
the bw?-? slices for, and why are they different sizes? Why are the
zmisc slices different sizes? What about ada0 and ada1? And, do you
have spaces in your GPT labels?
