Did you start up the cman first?

Unless you are planning to use gnbd outside of a cluster (and if you
want fencing, you need to use run gnbd in a cluster), you need to start
cman first.  gnbd_import failed when it called cman_init(). The most
likely reason for this is that your cluster is not started yet.
