[Linux-cluster] GNBD: cannot connect to cluster manager ...Operation not permitted

[Derek Anderson]

Christian,

You need to execute the cluster setup steps on the page you linked below 
(previous to the GNBD-specific sections).  Specifically, on each node you 
need to run: modprobe lock_dlm, ccsd, cman_tool join, and fence_tool join 
after you have cman quorum.  Then you should be able to gnbd_export devices.
