Erk, I fear you mis-understand ... FreeBSD has a feature called 'VINUM',
which is a volume manager ... basically, it allows you to create RAID or
Stripe'd file systems (or concat ones) ... what growfs allows is someone
to add an n+1 drive to their RAID/Stripe and increase the size of the file
system by that drive, without having to backup the drive, re-format and
then restore ...
I've used Solaris' version and have been much waiting for it to become
available under FreeBSD ...
