Proposal for a RN entry below.
Arvin, can you check if my added prose is (technically) ok? The command line
stuff is taken from the TID, so it should be fine.
Btrfs: Disk Space Leak after System Rollbacks
openSUSE 13.2 used a Btrfs partition layout that allowed for disk space
to become permanently occupied with stale, inaccessible contents after the
first system rollback was executed.
This layout issue was fixed in openSUSE Leap 42.1, but only for newly
installed systems.
If you are upgrading from openSUSE 13.2, you cannot actually convert the
to the new layout, but you can reclaim the lost disk space.
1. Mount the initial root filesystem after a rollback:
mount /dev/<root> -o subvol=@ /mnt
2. Remove all files below /mnt that are not in a subvolume:
find /mnt -xdev -delete
3. Umount the filesystem again:
umount /mnt
