[Linux-cluster] can't import gnbd ?

[Figaro Yang]

Dear Ben :

Thank you for your kindly reply. I still have another question as follows:

the host client is one of GNBD client in my cluster, does it need to start
cman service at client host? 
The host client is not suppose to be included in /etc/cluster/cluster.conf.

My cluster architecture is as below:

Hosta ( GFS / GNBD Server )  ---------|
Hostb ( GFS / GNBD Server )  ---------| ------------ SAN Storage
Hostc ( GFS / GNBD Server )  ---------|
       |
       |
       |
       --------------- client ( GNBD Client )

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.
