My LUKS disk is created some years ago the options would be outdated right now, if to change my LUKS header by:



# cryptsetup-reencrypt /dev/sdaX


WARNING: this is experimental code, it can completely break your data.
Enter passphrase for key slot 0:
...


If I do it with a specific option, will the ignored options of cryptsetup-reencrypt use the default? like:



# cryptsetup-reencrypt --iter-time 3500 /dev/sdaX


And cryptsetup-reencrypt is designed for no data loss in regular situation?

If by "ignored", you mean the ones that you don't pass, then yes.




And cryptsetup-reencrypt is designed for no data loss in regular situation?




It's designed to not lose your data, but as the warning you saw indicates, it might lose it anyway. Make sure you have a backup before using it.
