You'll need to use vinum as a volume manager first. Wouldn't recommend it at
all on a mounted filesystem, this can give you alsorts of worries.

I'd think about why you need to grow the volume, esp as any expansion of a
RAID set will normally result in poor performance, unless you backup the
data, rebuild the RAID set/filesystem and then restore the data.

IE plan for any changes first.

From what I can gather, it's not possible. Aside from the fact that
fdisk(8) says "Editing an existing slice will most likely result in the
loss of all data in that slice", growfs(8) says it cannot enlarge a
mounted filesystem. disklabel seems to be okay with making live changes,
but I haven't tested it.

Is there any way to do this in FreeBSD or is Linux+LVM the way to go?
