[solved] Unable to mount partition with specific UID since 6.8

Djabx commented 7 months ago

Describe the bug

I'm unable to mount btrfs partition with a specific UID.

Steps To Reproduce

Steps to reproduce the behavior:

configure a subvolume with a uid:

fileSystems."/home/alex/.cache" = {
options = [
  "noatime"
  "autodefrag"
  "uid=1000"
];
};

nixos-rebuild boot --upgrade
reboot
does not work

Expected behavior

Was working properly the 07/03; did not change anything in my system configuration; just try to build/update.

Additional context

All file / outputs are here: https://gist.github.com/Djabx/ef86c7b565559e2fa9a71b730d109a09

I've commented all volumes with an UID and I can boot properly. But I need thoses volumes.

Does it work without the UID setting?

Yes it does. That what is strange for me.

Note: My BTRFS Partitions are on a LUKS partitions; but it work properly in 6.7*

I'm on linux 6.7 and passing the uid=1000 option to a btrfs mount command gives me

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

That option isn't supported by btrfs and I'm surprised you didn't get this error before. The error you're getting now is expected behavior.

Damn you're right ! Thank you very much.
