GFS on CentOS - cman unable to start
 
Howdy, y'all. I'm trying to set up GFS in a cluster on CentOS systems
running on vmWare. The GFS FS is on a Dell Equilogic SAN.

I keep running into the same problem despite many differently-flavored
attempts to set up GFS. The problem comes when I try to start cman, the
cluster management software.

[root@test01]# service cman start
Starting cluster:
Loading modules... done
Mounting configfs... done
Starting ccsd... done
Starting cman... failed
cman not started: Can't find local node name in cluster.conf
/usr/sbin/cman_tool: aisexec daemon didn't start
[FAILED]

[root@test01]# tail /var/log/messages

I've seen much discussion of this problem, but no definitive solutions.
Any help you can provide will be welcome.

Hi,

same problem here, maybe you could find a solution.

and here the example of "cluster.conf"

I know nothing about GFS or clustering, just did some G search

good luck
