  • lsblk -o +UUID,PARTUUID
  • lsblk -o +UUID,FSTYPE,PARTUUID

01. USB drive has not been inserted (plugged in) yet.


02. GUI password prompt when drive is plugged in (I clicked cancel to demonstrate mounting from commandline).


03. USB drive inserted (plugged in) and showing as /dev/sdm1.


04. udiskctl showing /dev/sdm1 as "crypto_LUKS".


05. Trying to mount the locked LUKS encrypted volume (Failed because volume is locked. Run cryptsetup first to unlock.).


06. Running cryptsetup to unlock the encrypted volume (Assigning alias of "2T_SSD" to reference the unlocked volume. The alias can be whatever you want.).


07. Decrypted volume showing the 2T_SSD alias, but not yet mounted.


08. Decrypted volume alias "2T_SSD" showing under /dev/mapper.


09. Password prompt when using sudo to mount decrypted 2T_SSD volume to /dev/m.
