UTM MacOS Silicon: Adding A 32 GB VirtualDisk



ℼ

DISK SIZE (/dev/vdb): 32 GB



ℼ



ℼ

Crosscheck /dev/vdb

First, start (boot) your system, and next, login.

  • Account: root
  • Run:
lsblk


root:~# lsblk

NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0     11:0    1 1024M  0 rom  
vda    254:0    0   24G  0 disk 
|-vda1 254:1    0  512M  0 part /boot/efi
|-vda2 254:2    0 22.5G  0 part /
`-vda3 254:3    0  976M  0 part [SWAP]
vdb    254:16   0   32G  0 disk 

root:~#

In this case, the next disk is /dev/vdb

Partitioning 32GB

  • Account: root
    • Remember: you are not cbkadal! Replace "cbkadal" with your account.
  • Run:
DEVICE TYPE SIZE
/dev/vdb1 ext4 10 MB
/dev/vdb2 ext4 the rest 
{% raw %}
# REV01: Sun 17 Sep 2023 21:30
# START: Thu 29 Jun 2023 09:00
sync
# CLEAN OLD DISK
dd if=/dev/zero of=/dev/vdb bs=1M count=1
sync
# SFDISK is a script-oriented tool for partitioning.
sfdisk /dev/vdb <<< "
label: dos
device: /dev/vdb
unit: sectors
sector-size: 512
/dev/vdb1: type=83, start= 2048, size=20480
/dev/vdb2: type=83, start=22528
"
{% endraw %}

Crosscheck Again /dev/vdb1 and /dev/vdb2

  • Account: root
  • Run:
lsblk

UUID

In file "/etc/fstab"; replace "/dev/vdb1" and "/dev/vdb2" with its UUID. To find out UUID, run (root):

blkid

After replacement, file "/etc/fstab" should look like:
