FreeBSD disk/partition resize – grow on version 8.2 and newer under vmware vSphere / ESXi
This one is easier than previous (FreeBSD 7.x or older).
It may be possible to do it all live but you need to find a way for FreeBSD to see the growed disk size.
- Shut down the server
- Grow the disk size
- Boot FreeBSD in single user mode (number 4 at boot)
Check the partitions layout:
gpart show
Set the system in evil mode that will allow gpart to change live filesystem:
sysctl kern.geom.debugflags=16
Grow the whole disk – consumer. Number 1 is the consumer index shown with gpart show
gpart resize -i 1 da0
Grow desired provider – partition. Number 6 is the provider index shown with gpart show
gpart resize -i 6 da0s1
Now with partition resized you can growfs
growfs /dev/da0s1f
Reboot for a clean feeling and you’re done.

Hello Simon,
I am having problems resizing my partition /usr… from your experience if you could tell me what could be wrong…
Below I am sending to you some outputs:
# df -h
