I needed to move the /home directory on the boot/root drive to another disk to free up space.

This meant replicating the data to the other drive, then mounting the encrypted boot drive offline so I could clean out the /home dir.

Booting into single user mode to perform this task isn't an option because the root '/' dir is mounted read-only and remounting it read-write is not allowed.

What to do?

  • Boot using separate media such as the Elementary OS installer's "Try Elementary OS" option
  • Unlock the root partition: cryptsetup luksOpen /dev/sda5 root_crypt
  • Verify the LVM group name - it should be 'elementary-vg': vgscan
  • Activate the volume: vgchange -ay elementary-vg
  • Mount the decrypted, activated LVM volume: mount /dev/mapper/elementary--vg-root /mnt/
  • Work with files as needed
