Public bug reported: I have a server with Ubuntu 12.04 LTS running on it and a SAN attached to it via iSCSI + multipath. When shutting down/rebooting the system the network is shut down before the iSCSI volumes are unmounted and iscsi is shut down. Thus the volume can't be flushed and i run into potential data-loss. So at least those filesystems imported via the network need to be unmounted before the network is shut down.
