 Resizing FreeBSD disk under Bhyve (OmniOS) Host
+-----------------------------------------------

// show the details of the bhyve guest zfs dataset:

rpool/freebsd-guest  volsize   5G       local         


// rezise zfs volume to new desired size:
OmniOS #: zfs set volsize=25G rpool/freebsd-guest 


// confirm new size is set:
OmniOS #: zfs list rpool/freebsd-guest

 Setup FreeBSD guest to boot into live cd
+----------------------------------------
 
//add cdrom to guest to boot into live disk to edit virtual disk device:
# zadm edit freebsd-guest
   "bootorder" : "cd",                                         
   "cdrom" : "/zones/iso/FreeBSD-13.0-RELEASE-amd64-disc1.iso",
# zadm start freebsd-guest
# zlogin -C freebsd-guest

 Resize disk in FreeBSD guest using gpart & growfs
+-------------------------------------------------

// ... at the "Console type [vt100]:" prompt, enter "xterm" then choose < Shell >.

// edit virtual disk device:
// full details: (https://docs.freebsd.org/en/books/handbook/disks/#disks-growing)
// continue at your own risk 

// show device details 
# gpart show  vtbd0

// recover if necessary 
# gpart recover vtbd0

// delete swap partiton 3
# gpart delete -i 3 vtbd0

// expand partition 2
# gpart resize -i 2 -s 23G -a 4k vtbd0

// add the remainder of drive as swap
# gpart add -t freebsd-swap -a 4k vtbd0
# swapon /dev/vtbd0p3

//grow the filesystem
# growfs /dev/vtbd0p2

+--------------------------------------------
 reboot into new resized system
+--------------------------------------------

// halt the freebsd-guest
# halt

// poweroff the guest from bhyve (OmniOS) host
OmniOS #: zadm poweroff freebsd-guest

// restart into resized freebsd-guest
OmniOS #: zadm edit freebsd-guest
  // remove lines regarding cd
OmniOS #: zadm start freebsd-guest
OmniOS #: zlogin -C freebsd-guest
