So, what would you plan for normal home users on disk failure for Disk
Encryption? How to cope with it?
Hi, I guess what you are referring to can happen if you get bad sectors
where the luks header resides. This is a single point of failure in luks
whole disk encryption, to plan for this you must have current backups
(but most likely on another encrypted media, so there is always a tiny
probability that this is going to happen there too), and backup the luks
headers (see command "cryptsetup luksHeaderBackup"). See cryptsetup man
for security good practice regarding the headers backups.
