I have a 120GB drive using ZFS that I'm cloning to a 300GB drive since I know I will outgrow it soon.
It just dawned on me that I've never extended a drive using ZFS before.
Partition 1) EFI (512MB)
Partition 2) ZFS data + OS root (111GB)
Partition 3) Not sure (15GB) maybe left over...
Who can tell how to increase the disk space allocated under /usr/home?
# cat /etc/rc.conf | grep zfs
# cat /etc/rc.conf | grep vmw
