I have had no problem starting gnbd_serv without the -n option. If you try to start gnbd_serv without a cluster manager running on the node, you will receive a message like this on the command line gnbd_serv: ERROR cannot get node name : No such process gnbd_serv: ERROR No cluster manager is running gnbd_serv: ERROR If you are not planning to use a cluster manager, use -n and like this in syslog ERROR [gnbd_serv.c:389] If you are not planning to use a cluster manager, use -n This is not a gnbd error. This means that the cluster has not been properly started. Not only must there be a working cluster, but the gnbd server node must be a cluster member. In the min-gfs.txt document, the gnbd server node is not a cluster member, so you will not be able to export uncached gnbds with this setup. If you believe that the gnbd server node is a member of a quorate cluster, you can do this check. run # ccsd # cman_tool join on all cluster nodes. Then run # cat /proc/cluster/status For "Membership state:" you should see "Cluster-Member" For "Nodes:" you should see the number of nodes you expect there to be. If the cluster has not started up, you will not see a "Nodes:" section, and "Membership state:" will say something like "Starting" or "Not-in-Cluster". If you are a cluster member, and you still cannot start up gnbd_serv, please run it with the -v option, and send me the command and log output, along with the output from # cat /proc/cluster/status.
