Description Sjoerd Mullender 2022-12-28 09:24:53 UTC 
Description of problem:

Before upgrade of btrfs-progs, using btrfs-progs-6.0.2-1.fc37.x86_64:

$ sudo btrfs subvolume list -u /
ID 256 gen 148466 top level 5 uuid 57760724-47c5-b748-b49c-ae5f1c41e14a path root
ID 257 gen 148466 top level 5 uuid d9e13a78-41bd-4b42-8a60-10b15ecae5c1 path home
[...]

After upgrade of btrfs-progs to btrfs-progs-6.1-1.fc37.x86_64:
$ sudo btrfs subvolume list -u /
ID 256 gen 148478 top level 5 uuid -                                    path root
ID 257 gen 148478 top level 5 uuid -                                    path home
[...]

Where did the UUID go?  No reboot in between, just dnf upgrade.


Version-Release number of selected component (if applicable):
btrfs-progs-6.1-1.fc37.x86_64

How reproducible:
100%.

Steps to Reproduce:
1. Pretty clear from the above, I would think.
2.
3.

Actual results:
ID 256 gen 148478 top level 5 uuid -                                    path root
ID 257 gen 148478 top level 5 uuid -                                    path home

Expected results:
ID 256 gen 148466 top level 5 uuid 57760724-47c5-b748-b49c-ae5f1c41e14a path root
ID 257 gen 148466 top level 5 uuid d9e13a78-41bd-4b42-8a60-10b15ecae5c1 path home

Additional info:
My btrbk backups are failing with the message that there is no subvolume UUID.
