Bigger disk for GELI partition

[weberjn]

I have a system on a disk with an unencrypted start partition to reboot -r into the main GELI partion.

How would one move these disk to a bigger one? How would one resize the GELI partition?
I have another FreeBSD system that I could mount the disks.

How would one move these disk to a bigger one? How would one resize the GELI partition?

1 - Boot into the geli(8) encrypted system
2 - Insert a external USB device, mount device
3 - Backup geli(8) metadata of provider to file:

# geli backup -v ada0p4 /mnt/ada0p4.key

4 - Insert a FreeBSD installer image, reboot system into installer image
5 - At the installer images "Welcome" dialog window drop to "Live CD"
6 - Clone the system from the small disk to big disk:

dd if=/dev/small_disk of=/dev/big_disk bs=1m status=progress

7 - Recover corrupted GPT/MBR partition table of big disk (assuming here ada0)

# gpart recover ada0

8 - Resize partition of geli(8) provider (there might be error messages, ignore them):

# gpart resize -i 4 ada0        (resize to remaining free space or specify size, see below)
                                        
# gpart resize -s 10g -i 4 ada0  (resize partion 4 + 10GB)

9 - Mount USB device with the backed up geli(8) metadata
10 - Restore geli(8) metadata of provider:

# geli restore -vf /mnt/ada0p4.key ada0p4

10 - Reboot into big disk geli(8) encrypted system

EDIT: In addition the file systems size needs to be increased as well, for UFS growfs(8), for ZFS zpool-online(8) -e.
