Virtualized PFSense installation on UnRaid (KVM) - Expand storage

[sport]

I am able to increase the size of the VHD in the virt settings, but am not sure how to go about getting the PFSense environment to see the additional space.

is someone able to point me in the right direction or is this not possible with out reinstalling?

Try

touch /root/force_growfs

and reboot.
