- Assign another LUN to the system (e.g. dev/mapper/360000000000000000000000000000010)
- Create a GPT partition table.
- create a PReP partition of about 8MB size /dev/mapper/360000000000000000000000000000010-part1
- create a second partition consuming all free space on the LUN e.g. /dev/mapper/360000000000000000000000000000010-part2
- pvcreate /dev/mapper/360000000000000000000000000000010-part2
- vgextend system /dev/mapper/360000000000000000000000000000010-part2
- lvextend -L+20G /dev/system/root
- btrfs filesystem resize max /
Now install the bootloader on BOTH PReP partitions
- grub2-install /dev/mapper/360000000000000000000000000000000-part1
- grub2-install /dev/mapper/360000000000000000000000000000010-part1
