notes to self... with all the encryption management I am having to do, have to stop going back to my sent email folder for these notes...

First, you need to find out which is the encrypted LVM partition, it may be sda3, but it can also be sda5, sdX2, ...:

cat /etc/crypttab

Toadd a new password, use luksAddKey:

sudo cryptsetup luksAddKey /dev/sda3

Toremove an existing password, use luksRemoveKey:

sudo cryptsetup luksRemoveKey /dev/sda3

View currently used slots of the encrypted partition:

sudo cryptsetup luksDump /dev/sd3
