@pitti: please can you change the title to something that isn't so misleading. That would let others realise this same bug affects them.
With btrfs if you make a filesystem consist of multiple partitions then each of those partitions will get the same UUID because they are all parts of the same filesystem. This is not incorrect behaviour. PARTUUID and UUID_SUB will be unique per partition as expected, but those are not what you use in /etc/fstab I did a fresh install in Virtualbox with a RAID 0 btrfs and @ and @home subvolumes and it did work. My real system with considerably more drives is more complicated. How do I troubleshoot this? I need to know what systemd thinks it is doing and why. -- 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
