Re: [Linux-cluster] gfs2 and SAN setup



Hi Jeff,

 

Thanks for your reply. Our two servers are donuts (server1) and coffee (server2)  have been configured with CMAN but the outcome isn’t quite what we expect. On donuts a 'clustat' gives us some errors.

 

[root donuts ~]# clustat

Cluster Status for ngs @ Mon Jun 28 15:14:15 2010

Member Status: Quorate

 

Member Name                                                ID   Status

------ ----                                                ---- ------

donuts.microslu.washington.edu                                 2 Online, Local

Node1

                                                         1 Offline, Estranged

 

My cluster.conf file reads as following on this machine.

 

[root donuts ~]# cat  /etc/cluster/cluster.conf

<?xml version="1.0"?>

<cluster alias="ngsCluster" config_version="7" name="ngs">

        <fence_daemon post_fail_delay="0" post_join_delay="3"/>

        <clusternodes>

                <clusternode name="coffee.microslu.washington.edu" nodeid="1" votes="1">

                        <fence/>

                </clusternode>

                <clusternode name="donuts.microslu.washington.edu" nodeid="2" votes="1">

                        <fence/>

                </clusternode>

        </clusternodes>

        <cman/>

        <fencedevices/>

        <rm>

                <failoverdomains/>

                <resources/>

        </rm>

</cluster>

 

However, when I try to do the same on coffee, I am unable to start cman. I've copied donuts cluster.conf file to  this machine but gets overwritten with a cluster.conf file that just has 'donuts' in it every time I try to restart CMAN.

[root coffee cluster]# clustat

Could not connect to CMAN: Connection refused

[root coffee cluster]# /etc/init.d/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]

 

 

Thanks!

JJ

Make sure CMAN is running on all nodes, and all nodes have successfully joined the cluster.
