[Linux-cluster] ERROR cannot get node name

[Sridharan Ramaswamy (srramasw)]

I'm a newbie too and got similar error while trying to get min-gfs setup
working. Steps in min-gfs skips the whole cluster configuration using
"-n" (which is kinda neat to get started). 
 
Try adding "-n" to gnbd_import similar to your gnbd_serv(see man
gnbd_import).
 
/sbin/gnbd_import -n -i boston
 
I presume min-gfs document should be updated/corrected for this. 
 
Getting this to work with cluster mode (i.e. without -n) involves
starting ccsd, cman and creating an appropriate cluster.conf. 
 
thanks,
Sridhar

	Ok, well I am still following the mini how to that is included
in the tar ball.
	
	When I go to startup everything on the node I get the following:
	
	[root at perforce2 cluster-1.03.00]# depmod -a
	[root at perforce2 cluster-1.03.00]# modprobe gnbd
	[root at perforce2 cluster-1.03.00]# modprobe gfs
	[root at perforce2 cluster-1.03.00]# modprobe lock_dlm
	[root at perforce2 cluster-1.03.00]# gnbd_import -i boston
	gnbd_import: ERROR cannot get node name : No such process 
	gnbd_import: ERROR No cluster manager is running
	gnbd_import: ERROR If you are not planning to use a cluster
manager, use -n
	[root at perforce2 cluster-1.03.00]# 
	
	Is there something I forgot?
	
	here is the selection from the file: 
	
	- load kernel modules on nodes
	
	node2 and node3> modprobe gnbd
	node2 and node3> modprobe gfs
	node2 and node3> modprobe lock_dlm
	
	- run the following commands
	
	node1> gnbd_serv -n 
	node1> gnbd_export -c -d /dev/sda1 -e global_disk
	
	node2 and node3> gnbd_import -i node1
	node2 and node3> ccsd
	node2 and node3> cman_tool join
	node2 and node3> fence_tool join
	
	node2> gfs_mkfs -p lock_dlm -t gamma:gfs1 -j 2
/dev/gnbd/global_disk 
	
	node2 and node3> mount -t gfs /dev/gnbd/global_disk /mnt
	
	- the end, you now have a gfs file system mounted on node2 and
node3
