Hi Giovanni, I think I see where you're going with this. I incorrectly assumed that disk c8t0d0 was my rpool, because it's at the top of the list with the "format" command. However "zpool status" shows that my rpool is actually disk c8t5d0. But then why, when I try to format c8t0d0, does it say "c8t0d0s0 is part of active ZFS pool rpool". Surely both disks can't be part of my rpool, can they?
