Can't use bcachefs with internal encryption

I want to change my very custom structure with dm-crypt, bcache and LVM into bcachefs-based, much simpler (from the operational structure). I plan to go into that all the way when the LTS kernel appears that has bcachefs merged, but for now I just have unmasked 6.11.2.

It works, but I can't use encryption. I created a filesystem with encryption supported but no master key, and want to change a passphrase, but I see `scrypt error: -1`:[/code]

Do you have emerged sys-fs/bcachefs-tools ?

Yes, I have shown that I am using the program "bcachefs" which is provided by that package. It is what throws the scrypt error.

yes ... sorry ... :oops:

... sometimes I get confused

First of all: I haven't ‘played’ with bcachefs for a while, so it might be outdated.

I had a problem back then that I had to solve with ‘keyctl link @u @s’. Have a look there: https://wiki.gentoo.org/wiki/User:Pietinger/temp/test

That error (requested key not available) I’ve seen in my other attempts. Well, although that’s not my case, it may be related.

OK, now at least I have something useful to read and, hopefully… Thank you.
