Migrating containers live or non-live uses the same filesystem backing code to do it, since it needs to migrate the filesystem in both cases. I have a branch that makes smarter per-backend decisions when you are using a filesystem like ZFS or BTRFS, but it still has some bugs that need to be worked out and I haven't gotten much time to work on it recently. We don't have a ceph (or block) backend today, so as Serge says there is no way for LXD to understand that it shouldn't try to move the FS today. I think we'd be happy to accept such a backend as a patch, though :) Tycho _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
