Hi there,
I think you are just one step away from success, please do allocate space of the whole disk to c4d0s0 before issuing zpool attach -f rpool c3d0s0 c4d0s0
Current slice layout on your c4d0 does not allocate space to slice 0, only a small s8, s2 is traditionally a special slice to indicate the whole disk (for using in backup utility,) use a big s0 instead.
Cheers,
Ivan.
