Hi Christian,

| Jul 19 20:28:13 gfs1 receiver[22551]: ERROR [gnbd_clusterd.c:53] cannot
| connect to cluster manager : Operation not permitted

Did you start gnbd_serv?

If so, check the permissions of /dev/gnbd_ctl. Eventually the are wrong
(they where here). If you run the 'gnbd_export' with 'strace' you will
see more.

I remember that using devfs one needs something along the following
lines in /etc/devfs.d/gnbd:

#
# GNBD
# gnbd needs crw------- on /dev/gnbd_ctl
#
REGISTER   ^gnbd_ctl    PERMISSIONS root.root 600
