luks encrypted hard drive didn't accept correct Password

[Gladdle]

The Topic says it all, i have installed gentoo on a luks encrypted hard drive. I shut down normally, next day i start it. Typed in my password and it didn't accept it anymore. This i have tried:

- I cleaned the keyboard so maybe a mechanical issue -> error "No key aviable with this passphrase."
- tried another keyboard -> error "No key aviable with this passphrase."
- I boot from the live DVD, set the correct keyboard layout, tried in plain text (to read) and copy this to open the disk with "cryptsetup luksOpen /dev/sda2 LinuxLVM" -> error "No key aviable with this passphrase."

I DON't have updated my kernel, NOR GRUB2

So HOW can that be? I DIDN'T change my password! Someone got some Ideas or are ALL my files gone for now?


Update #1:
I used

maybe it's just a keyboard layout issue and therefore it's defaulted to US and not DE, while at boot.

querty instead of quertz

if you have some symbols in your passphrase, search for images of US defaulted keyboard layout and try again.

have you not created a second passphrase as a backup, e.g very long Numbers only ?

copy and paste could add another key without noticing, e.g. at the end.

Gladdle,

Kernel device names are not deterministic. They are allocated in device discovery order.
Its possible that several devices of the same type will swap kernel device names.

e.g. You have two HDD. sda and sdb. They can be discovered either way round, so the names will swap.

Are you sure you are dealing with the right device?

@CooSee
Like i told in my first post: I also copy the plaintext Password per drag and drop, use a other keyboard and so on.

@NeddySeagoon
I use UUID's in my config and also a LiveDVD where i speccialy used the right device.



I'll think i make a "backup" from the header and try a brute force crack tool, and i am sure in a million years i finnaly can open it again...



To all the guys using google and come here:
It's important to make a BACKUP after you created the device and maybe use a second password or a Keyfile (this time i did it...)
