Salutations. Thank you all so much for the time and effort you put into your amazing project!I've used it successfully many times! I have a usage question for you if you'll allow me. I am attempting to create a detached header in conjunction with a 1G offset. The version of cryptsetup I am using is version 2.2.2. My kernel is 5.4.3 What I expected: > detached header file "detached_header.img" on /dev/sda1 (mounted at /mnt)> luks protected data on /dev/sda1 The command I used.> $cryptsetup luksFormat /dev/sd2 --offset 2097152 --header /mnt/detached_header.img According to the man page, the --header option will override the positional <device> parameter. Thus, when I run the above command (or variations of same) the device on which the "detached_header.img" file sits, becomes the target of the luksFormat. What happened:> /dev/sda1 becomes target of luksFormat. Fails with the following output; $ Device wipe error, offset 93323264.$ Cannot wipe header on device mnt/detached_header.img No change on /dev/sda2 I know I'm misunderstanding something, but I can't figure out what it is. Thank you ahead of time for any help you can provide! -Omar _______________________________________________ dm-crypt mailing list [email protected] https://www.saout.de/mailman/listinfo/dm-crypt
