I just installed Debian Buster with encrypted LVM.
In my fstab file, I have:

I can't figure out what device I should pass to cryptsetup to avoid the
below error:
$ cryptsetup -v luksAddKey /dev/mapper/try02--vg-root /etc/keys/root.key
--key-slot=1
Device /dev/mapper/try02--vg-root doesn't exist or access denied.
Command failed with code -4 (wrong device or file specified).
How can I know what device cryptsetupt will accept?
It looks as if you're trying to add the key to the decrypted device,
ie the /dev/mapper/ device that gets mounted as /.
You add keys to the encrypted device, ie the device that contains the
encrypted filesystem, the argument you used in the command
# cryptsetup luksFormat <this-device>
The debian -installer has done that for me, I don't understand how I can
get the encrypted device.
