I use a keyfile of 1MB in size. Upgraded to rc9f, inputted my keyfile, and server was unable to mount any of my disks with the following error repeated for each one. Reverting to rc8q allowed me to mount the drives again.

Version rc8 does not store a binary file in the proper format, this has been corrected in rc9. You need to redo the encryption when using a keyfile.

 

Ah thanks a lot! Now that you point it out, the md5sum, sha1, and sha256 of the keyfile are different on the file than they should be. Strange, but understandable.

Thanks for the pointer. I was able to use cryptsetup luksAddKey to temporarily add an additional password key to the drives, upgraded to rc9f, then re-added the keyfile correct keyfile. No need to start over with luks support
