Apologies for misleading you - I thought you were more familiar with btrfs. The summary change is incorrect and btrfs is doing the right thing. Quite simply the filesystem is made up of more than one partition, so more than one partition correctly has the same UUID. But that also means looking at /dev/disk/by-uuid/UUID can only point to one of the partitions making up the filesystem UUID.
The btrfs wiki talks about multiple devices: https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447879 Title: fscking btrfs mount fails with non-unique UUIDs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1447879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
