To debug I tried a more > traditional location /dev/hda1, [...] that is the problem: * /media/sda1 is a a mount location - just a directory * /dev/hda1 is a block device so the output of the following commands should be different: cryptsetup luksAddKey /media/sda1 KEYFILE cryptsetup luksAddKey /dev/hda1 KEYFILE the first outputs "failed to open device" and the other one "no luks device". Just as Dick Middelton suggested in his mail: use the device instead of the mountpoint (as written in the manual) - in your case: /dev/sda1 hope that helps, regards, Lars --------------------------------------------------------------------- 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
