I added a disk for the mirror, ada1
# gpart destroy -F ada1
ada1 destroyed
# gpart backup ada0 | gpart restore ada1
# gpart modify -l sys1 -i 2 ada1
ada1p2 modified
# gpart show -l ada1

When I try to run the zpool attach command I receive the error:
# zpool attach pool_ssd gpt/sys0 gpt/sys1
cannot attach gpt/sys1 to gpt/sys0: can only attach to mirrors and top-level disks

What can I do ?
Thanks.
