Current approach

mkdir /mnt/drivename cryptsetup luksOpen /dev/sda1 drivename mount /dev/mapper/drivename /mnt/drivename

This worked

From the command line, mount an encrypted drive: modprobe dm-crypt fdisk -l cryptsetup open /dev/nvme0n1p3 filesys

Even messier way

Some more wizardry from the internet …. Let's hope this is never needed again. mkdir filesys vgscan echo 'vgdisplay | grep UUID | awk '{print $3}' > foo.txt vgrename $($lt; foo.txt) new_name vgdisplay modprobe dm-mod vgchange -ay vgdisplay lvscan mount /dev/new_name/root filesys Not sure how much, if any, of renaming part of the last part is necessary; maybe I just needed to include /root in the initial mount command?

Create an encrypted USB drive

sudo cryptsetup luksFormat /dev/sdx
