Re: [Linux-cluster] GFS on CentOS - cman unable to start



Hi,
The error log is clear

---------
Jan  5 13:40:24 testbench06 openais[3939]: [MAIN ] local node name  "test01.gdao.ucsc.edu" not found in cluster.conf
---------

And is related to the email i sent before. Give a try, you don't lose anything.

Hi Wes

Please excuse my poor english - it's not my mother language I'm writing in.

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]


I don't think that the cluster is your main-problem.
The nodename must "not" present in DNS, but it must be resolvable by files, ldap whatever.

Please verify that "files" is present at /etc/nsswitch.conf.

e.g: hosts:      files dns

Did you've check with "ip addr list" that the ip-address matches the same as in /etc/hosts?
