Yes, I found that documentation in the meantime and compared the first couple of blocks between my home partition and another (still working) LUKS partition. Somehow I managed to completely hose the first couple of blocks! I guess I gave the wrong device when configuring a encrypted /tmp with a key from /dev/urandom the night before or did something equally stupid. I tried to copy everything up to the key-blocks from the working LUKS partition (which had an identical configuration wrt. hash and crypto algorithm), but that did not help either. In the end I just did a cryptsetup luksFormat and restored my backups. If you still have an idea: I made a copy of the complete device with dd, so I can experiment on it. -- Tobias Hunger Senior Software Engineer basysKom GmbH Robert-Bosch-Str. 7 | 64293 Darmstadt | Germany Tel: +49 6151 3968769 | Fax: -9736 | tobias.hunger@xxxxxxxxxxx | www.basyskom.de Handelsregister: Darmstadt HRB 9352 Geschaeftsfuehrung: Eva Brucherseifer --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
