Operation:

  • sudo vgs: ubuntu-vg 1 1 0 wz--n- 462.69g 362.69g
  • df -T / : /dev/mapper/ubuntu--vg-ubuntu--lv ext4 102626232 24338224 73028744 25% /
  • sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
  • sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

Never did this before on an encrypted drive. Is this the proper procedure? Obviously a complete image back up is in order, however, are there any gotchas, caveats, pitfalls that I should be aware of before proceeding?

    You can’t resize the filesystem without first resizing the crypted volume.

    You would expand this LV. Expand the crypted volume. The decrypt the volume and expand the underlying filesystem.

      hmmmm…I thought that the command sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv would extend the encrypted volume, and this command sudo resize2fs /dev/ubuntu-vg/ubuntu-lv would extend the filesystem.

          Is the LUKS volume created right on the disk on a raw partition?

          Yes. I’m sorry for the confusion and incomplete info. I’m flying a little blind here. The first two commands in the OP were to check what I have, and the last two were to extend the LUKS and then the filesystem.

            I saw in another comment your lsblk output and yes I see the LUKS partition spans the whole disk.

            So yes, the commands you listed should be sufficient. It will extend the decrypted logical volume to use the remaining free space of your volume group.
