It just tosses the info in the end of your disk/slice/partition -- I think ;)
In your example, you had a da1d... you could do partition level mirroring instead of whole disk
level if you want. While a machine was running ... and you had data on da1d, run
gmirror label -v -b round-robin gm0d /dev/da1d
gmirror instert gm0d da0d (asusming your da0 is what you are mirroring to)
and you would have a 'parition level' gmirror...
You may need to umount the partition... not sure. Oh, there is the secret
command as well. Explained in the reference I always use when using gmirror:
