Public bug reported: btrfs-prog v4.16.x shipped with Ubuntu 18.10 cosmic has a regression that prevent incremental backup between subvolumes which have parent subvolume mounted on "/".
Ubuntu installer allows btrfs as install root and makes subvolume "@". `do-release-upgrade` makes snapshots "@apt-snapshot-*" while upgrading. In this case, incremental backup between those @apt-snapshot-* cannot be taken unless umount the root subvolume The fix has been merged into upstream v4.17, can be found here https://github.com/kdave/btrfs-progs/commit/09827a8a332fdb1b74f4e103b8b72b0b800b5d72 Thanks. ** Affects: btrfs-progs (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799927 Title: btrfs-progs: regression preventing send -p with subvolumes mounted on "/" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/btrfs-progs/+bug/1799927/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
