Hi, as far as I can tell, the header and keyslot look healthy. Of course some overwritten bytes in the Key-slot would not show, but they should not happen on the operations you describe. Make very sure you are inputing the correct passphrase. Maybe the keyborad-layout subtly changed? Did this same passphrase work before for you, i.e. do you have a clear good-before bad-after situation? You can send me the complete header (if you want, but not the data part please and not the passphrase) and I can have a look for obvious corruption. You find the information on how to do a header backup in the FAQ: http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions There may also be something wring with the LVM, e.g. overlapping partitions or the like. This could have done arbitrary damage, but should be visible in the key-slot data.
