On a side note there is not a simple way to glabel mounted filesystem

glabel is also great for doing silly things like things like this

glabel label leftdrive0 /dev/ad4
glabel label rightdrive0 /dev/ad5
gmirror label -v -b load raid1  leftdrive0 rightdrive0

this way when you get a gmirror status you can easily tell which drive
is doing what, red rebuilding etc .
