Correct. Attached is a juju-deployer config that reproduces the issue when used with the juju local provider and /var/lib/lxc in the host backed onto btrfs. If you deploy it and run juju destroy-environment --force -y local, it should fail.
This is because Ceph sees that /srv/ceph is on btrfs and makes use of it. ubuntu@vagrant-local-machine-1:~$ mount /dev/sda2 on / type btrfs (rw) So you'll end up with lots of snapshots created by Ceph inside LXC. These will be visible by running `btrfs subvolume list /var/lib/lxc` in the host: (.venv-ubuntu)vagrant@vagrant-ubuntu-trusty-64:~$ sudo btrfs subvolume list /var/lib/lxc ID 256 gen 9268 top level 5 path @lxc ID 257 gen 8126 top level 256 path juju-precise-template/rootfs ID 285 gen 8006 top level 256 path juju-trusty-template/rootfs ID 762 gen 9208 top level 256 path vagrant-local-machine-25/rootfs ID 763 gen 9208 top level 256 path vagrant-local-machine-26/rootfs ID 764 gen 9208 top level 256 path vagrant-local-machine-27/rootfs ID 925 gen 9208 top level 256 path vagrant-local-machine-27/rootfs/srv/ceph/current ID 934 gen 9208 top level 256 path vagrant-local-machine-26/rootfs/srv/ceph/current ID 944 gen 9208 top level 256 path vagrant-local-machine-25/rootfs/srv/ceph/current ID 951 gen 9208 top level 256 path vagrant-local-machine-26/rootfs/srv/ceph/snap_4426 ID 954 gen 9208 top level 256 path vagrant-local-machine-26/rootfs/srv/ceph/snap_4483 ID 957 gen 9208 top level 256 path vagrant-local-machine-25/rootfs/srv/ceph/snap_4767 ID 958 gen 9208 top level 256 path vagrant-local-machine-27/rootfs/srv/ceph/snap_5753 ID 959 gen 9208 top level 256 path vagrant-local-machine-25/rootfs/srv/ceph/snap_4845 ID 960 gen 9208 top level 256 path vagrant-local-machine-27/rootfs/srv/ceph/snap_5754 ** Attachment added: "object-storage.yaml" https://bugs.launchpad.net/juju-core/+bug/1307215/+attachment/4154884/+files/object-storage.yaml -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307215 Title: destroy-environment fails to clear lxc containers To manage notifications about this bug go to: https://bugs.launchpad.net/juju-core/+bug/1307215/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
