Find Your New Disk

• VirtualBox vs. UTM
  • VirtualBox Disk Device names started with “sd”. E.g. /dev/sda, /dev/sda1, /dev/sda2, /dev/sdb, /dev/sdb1, …
  • UTM Disk Devices name started with “vd”. E.g. /dev/vda, /dev/vda1, …

Boot your Virtual Guest

• Login to your Virtual Guest
• Substitute as “root”

su -

cbkadal@cbkadal:~$ su -
Password: 
root:~# 

Find All Disks

cat /proc/partitions

(VirtualBox Result, UTM is different)

root:~# cat /proc/partitions 

major minor  #blocks  name
   8        0   67108864 sda
   8        1     498688 sda1
   8        2   66608128 sda2
   8       16   67108864 sdb
   8       17     498688 sdb1
   8       18   66608128 sdb2
   8       32       4096 sdc

• It is obvious that “/dev/sdc” is the new 4 MB (4096 Kb) disk!
• YOUR SYSTEM OUTPUT MAY BE DIFFERENT

Cross checking the current mounted disks

• find all mounted “/dev/sd” partitions for VirtualBox. For UTM, replace “sd” with “vd”.

df | grep \/dev\/sd

/dev/sda2       15421320 4795328   9820824  33% /
/dev/sdb2       31861548 2087496  28130020   7% /mnt/lfs

• here exists “/dev/sda” and “/dev/sdb”
• therefore “/dev/sdc” must be the new disk.
• YOUR SYSTEM OUTPUT MAY BE DIFFERENT

(In This Example) Your device is “/dev/sdc”
