Re: [Linux-cluster] Cannot make cluster after upgrade



Sounds a little split-brainish....... have you tried the clean_start=1 option?

After an upgrade from 5.2 to 5.3, the cluster, named GFSCluster, seems to stop being a cluster. GFSCluster is a 2 node cluster using iscsi, cman, clvm, and gfs and it was working fine when it was on 5.2 The configuration on both of the nodes (passwords removed)

<?xml version="1.0"?>
<cluster name="GFSCluster" config_version="5">
<cman expected_votes="1" two_node="1"/>

 <fencedevices><fencedevice name="node01_ipmi" agent="fence_ipmilan" ipaddr="10.1.0.5" login="root" passwd="********"/><fencedevice name="node02_ipmi" agent="fence_ipmilan" ipaddr="10.1.0.7" login="root" passwd="********"/></fencedevices>
 <rm>
   <failoverdomains/>
   <resources/>
 </rm>
</cluster>

When starting the service cman, they both hang on the part starting fencing

Starting cluster:
  Loading modules... done
  Mounting configfs... done
  Starting ccsd... done
  Starting cman... done
  Starting daemons... done
  Starting fencing...

After 5 minutes the task finishes with "done" but clustat says

==== As root on web01.company.com ====

They are both quorate with their own cluster

In the logs of web01 I found repeating messages

Jul  8 00:55:27 web01 fenced[21872]: node02.company.com not a cluster member after 6 sec post_join_delay
Jul  8 00:55:27 web01 fenced[21872]: fencing node "node02.company.com"
Jul  8 00:55:52 web01 fenced[21872]: agent "fence_ipmilan" reports: Rebooting machine @ IPMI:10.1.0.7...ipmilan: Failed to connect after 30 seconds Failed


In the logs of web02 I also found the same repeating messages

Jul  8 00:55:27 web02 fenced[6363]: node01.company.com not a cluster member after 6 sec post_join_delay
Jul  8 00:55:27 web02 fenced[6363]: fencing node "node01.company.com"
Jul  8 00:55:53 web02 fenced[6363]: agent "fence_ipmilan" reports: Rebooting machine @ IPMI:10.1.0.5...ipmilan: Failed to connect after 30 seconds Failed


Is there a bug on 5.3 with regards to clustering?
Is there any workarounds?
