My question over here is How do we unlock an encrypted volume using the Master key? this is without having to add a new passphrase.
Hm, this is interesting... it is possible through libcryptsetup API, but cryptsetup CLI allows using --master-key-file only in luksFormat and luksAddKey. It should be easy to add, if you can add issue on project page I will add it to next version (for luksOpen). For now, I think the only "simple" shell solution is to not only store master key, but whole mapping table "dmsetup table --showkeys" and activate volume using dmsetup create <name> --table "<stored table>" (bypass LUKS completely - can be dangerous if wrongly used). (in mapping table you can replace device to path to snapshot) It is not ideal solution though...
