I created a snapshot on a btrfs filesystem and lxc-snapshot correctly created a btrfs subvolume snapshot. However when restoring the snapshot, I got this instead:
> $ sudo lxc-snapshot -n rh65-dev -r snap0 > rsync: writefd_unbuffered failed to write 4 bytes to socket [generator]: > Broken pipe (32) > rsync error: error in rsync protocol data stream (code 12) at io.c(1532) > [generator=3.0.9] > lxc_container: rsyncing /var/lib/lxc/containersnaps/rh65-dev/snap0/rootfs to > /var/lib/lxc/container/rh65-dev/rootfs > > lxc_container: Error copying storage > lxc_container: _recursive_rmdir_onedev: failed to delete > /var/lib/lxc/container/rh65-dev > lxc_container: Error destroying container directory for rh65-dev > lxc_container: Error restoring snapshot snap0 There are a couple of problems with that: 1) lxc-snapshot is using rsync and not the btrfs snapshot tool, e.g. btrfs sub del fs btrfs sub snap snapshot fs btrfs sub del snapshot 2) lxc-snapshot has now deleted the original filesystem (it doesn't show up in the subvolume list) in such a way that I can no longer restore to the same path: > # rm -r /var/lib/lxc/container/rh65-dev/rootfs > rm: cannot remove ‘/var/lib/lxc/container/rh65-dev/rootfs’: Operation not > permitted I'm not really sure how that was accomplished.
