 Posted: Tue Jun 03, 2008 6:43 am Post subject: failed to setup dm-crypt key mapping |
 |
|
Hi
I've got a problem with cryptsetup.
I've formatted a harddisk on a archlinux-system with "cryptsetup luksFormat -y -c 384 -s lrw-benbi" ..or something like that. And on that system I could "luksOpen" it without any problems.
I've put this harddisk onto my gentoo system, emerged cryptsetup - and now I can't luksOpen it anymore.
"cryptsetup luksOpen --key-file /var.key" fails with:
| Code: |
Failed to setup dm-crypt mapping.
Failed to read from key storage
Command failed: No key available with this passphrase.
|
The same as in FAQ dm-crypt wiki www.saout.de/tikiwiki/tiki-index.php?page=LUKSFaq.
But I've controlled everything they say in there.
I have kernel 2.6.22-gentoo. I have loaded the same modules as on the old system.
On the archlinux I have some 2.6.24 kernel. Hmm...? Any ideas?

Moved from Portage & Programming to Kernel & Hardware, and the other one to the Dustbin. Please don't post the same question in more than one place - it makes it harder for anyone else who comes along later with the same problem to find the answer.

sry for double post.
My call and error: (same is when I try to do luksFormat an other partition)
| Code: |
molari ~ # cryptsetup luksOpen /dev/hdc6 hdc 6 --key-file /var.key
Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-lrw-benbi cipher spec and verify that /dev/hdc6 contains at least 383 sectors.
Failed to read from key storage
Command failed: No key available with this passphrase.

Here's some information that might be useful. Maybe there is still a module missing??

Shouldn't the lrw decryption show up in the last part of listing?
Does someone have a clue about all that? |

Somehow it runs now! I've just built a new kernel, but I changed afaik nothing dramatically. But for example the crypto_algapi module is no longer loaded.
Hmm, still have no clue.
Maybe it got to do, with the modules loaded... |
