Hi, I use LUKS since 2 weeks on my computer. I have juste shutdown it yesterday, and today, impossible to mount the partition. It's an ubuntu 7.10 but I use LUKS since more time on my other computer with Debian Etch. I have checked to have the good keyboard language and there was no kernel update or no update at all on ubuntu yesterday, so I don't understand. (And yes, I'm absolutly sure about the password...). /dev/mapper seems OK... In order to create the partition I have used luksFormat with no additionnal parameters (using the defaults). My question is: There is a technical problem, or some LUKS headers can be eventually be corrupted ? From what I have read, there is a single point of failure in LUKS. Can I be sure that's a corruption or can I try something else ? Thanks, reguards Leo # cryptsetup luksOpen /dev/sda6 sda6_crypt Enter LUKS passphrase: Enter LUKS passphrase: Enter LUKS passphrase: Failed to setup dm-crypt key mapping.
