- No I can't see the ganglia web interface on either the public or private interfaces, it says "you have no permission"
- the admin node is setup as a forwarding dns server and lookups seem to work correctly
- the firewall/iptables services have been stopped, with on an iptables rule set from the command line to forward and NAT traffic
- nscd cache has been turned off
- munge is running
- torque/maui packages did get updated, configurations have been check to make certain they were the same as before the update.
Thanks

Hi Richard,
- Can you see ganglia web interface?
- Are you using a DNS for your cluster?
- Are firewalld / iptables services stopped?
- Is nscd cache reseted?
- is munge running?
- I'm not using torque/maui anymore, so I can't check on my side to see if there are some specific config to check...
- were the torque / maui package got updated during the process?
Olivier.

Did check these before but I re-checked as below:
1. /etc/hosts are the same across the cluster.
2. can ssh to a node and back without any problems or password. The known_hosts file has been updated and copied across the cluster.
3. checked nagios/nrpe and it is setup to allow the admin node to collect details.
4. ganglia/gmond is setup to talk to the admin node.
5. pbs_server and maui on the admin have been restarted with no reported errors in the log files.
6. pbs_mom on the nodes has been restarted with no reported errors in the log files.
7. a search through /etc and /var/lib/torque for the ip-address of the server doesn't find anything other old log entries.
8. /etc/dhcp/dhcpd.conf has been updated.
9. /etc/ntp.conf has been updated across the cluster.
Thanks

Hi Richard,
I would like to double check the following items if I were you.
1. /etc/hosts, ssh keys, nagios/nrpe, gmetad/gmond are all synced through all the nodes.
2. Make sure that the root user can ssh into all the nodes back and forth without password.
3. All the daemons of the job submission are running on all the nodes:
(torque-server, torque-mom in the head node and torque-mom in the client nodes and maui on the head node)
I assume that you are using torque as RM and maui as a scheduler.
Regards,

The major change was changing the ipaddress of the oscar_server, this was required because changes to the network structure. The ipaddress has been applied to /etc/hosts, ssh keys, nagios/nrpe, gmetad/gmond etc. However, I have missed something because no jobs will now run on the cluster. The jobs basically site in the queue and then get cancelled because they have hit their walltime.
