Hey magical linux-oracle,

I recently made a full disk encryption on my computer via the debian installer.

I partitioned it like this:

SSD:

– unencrypted part –

Boot - 1GB space, mounting point: /boot

EFI - 512MB space, mounting point: ESP, bootable flag: on

– encrypted part –

Encrypted container with a volume group (vg-1) containing 3 logical volumes:

Root - 50GB space, mounting point: /

Swap - 30GB space, mounting point: swap

Home - Rest of space, mounting point: /home

& Second harddrive fully encrypted with one logical volume and mounting point /mnt/data


The install of linux worked pretty well.

Unfortunately, the hibernation part doesn’t work out of the box. When I press hibernate (or standby), it only goes to the lock screen. How can I solve that issue? (Is it even a good idea to use hibernation on encrypted devices?)

Second thing: As you can see from my setup, I use 2 disks. When I start up my system, I only need to enter my decryption password once (not twice for the 2nd HD) and I see, that my second hard disk seems to be mounted already. It seems that people usually struggle with typing in their passwords twice and want a solution for that. Is it possible, that debian automatically fixed this for me (It’s the same pw for both)?

Thanks!

    hibernation is in general not supported with full disk encryption, and is not recommended. you can do it but it’s a hassle and will lead to hangs on wakeup if you don’t configure it correctly. i gave up on it.
