Hello.
> You can try to use '-h' flag for `gmirror label` command.

How it can be done?

# gmirror status
       Name    Status  Components
mirror/swap  COMPLETE  diskid/DISK-SERIAL1p2 (ACTIVE)
                       diskid/DISK-SERIAL2p2 (ACTIVE)
# gmirror destroy swap
# gmirror status
# gmirror label -h -v -b round-robin swap diskid/DISK-SERIAL1p2
Metadata value stored on diskid/DISK-SERIAL1p2.
Done.
# gmirror insert -h swap diskid/DISK-SERIAL2p2
gmirror: No such device: swap.
# gmirror status
