Re: [Oscar-users] PBS configuration failure during post_install (OSCAR4+FC2)

[stlin]

Hi Bernard, The the address 10.0.1.10 was for my intranet network card (eth1) and I used ./install_cluster eth1 for the installation. BTW, I'd like to make it a bit more clear for the meaning of " hostname for the network should be the same in the PBSserver file". My understanding is that the hostname (one can get from %echo $HOSTNAME) should be on the same line as the name of the PBSserver (pbs_oscar) in the file /etc/hosts. In the example below my $HOSTNAME was abc.ntu.edu.tw. Thanks to you for your suggestions as well. Shiang-Tai Bernard Li wrote: Hi Shiang-Tai: Good work! This may be a potential bug that we might have to look into. One question though, assuming that 10.0.1.10 is the address of your eth1 interface, have you always been running: ./install_cluster eth1 ? Have you ever run install_cluster on eth0?

The problem (at least for me) was that the hostname for the network is not the same in the PBSserver file. That is, the name of the PBSserver, pbs_oscar (defined in /var/spool/pbs/server_name), is not defined in the file /etc/hosts. This should always be true if one has only one network card installed but may be setup incorrectly if there are additional network cards on the server node. To be more clear, I list my /etc/hosts file here (the xx are numbers I do not wish to disclose for security reasons) # Do not remove the following line, or various programs # that require network functionality will fail. 10.0.1.10 abc.ntu.edu.tw abc oscar_server nfs_oscar pbs_oscar 140.112.xx.xx def.ntu.edu.tw def # These entries are managed by SIS, please don't modify them. 10.0.1.1 node1.abc.ntu.edu.tw node1 10.0.1.2 node2.abc.ntu.edu.tw node2 Originally I had "10.0.1.10 def.ntu.edu.tw def oscar_server nfs_oscar pbs_oscar" in the /etc/hosts so the post_install always failed. I also want to note that it is not necessary to edit the nodes file /var/spool/pbs/server_priv/nodes. The post_install script can still find the nodes without this file. Finally, I'd like to point out that I figured this out after reading the following paragraph I found in http://www.mail-archive.com/oscar-users@lists.sourceforge.net/ msg01387.html "If the primary name on the interface is not the name in the PBSserver file, you will get get an "Unauthorized Request" error when you attempt to configure the server with qmgr." Thanks to all, especially Bernard, who tried to help me out. Shiang-Tai Yu Chen wrote: Hello, I can confirm Shiang-Tai's finding, it happened to me too, the same thing, although different system. I am using RH-EL-AS-3 update 3 on i386. The error messages are the same, I thought it's the "/opt/pbs/bin/pbsnodes: Server has no node list" problem, so I created /var/spool/pbs/server_priv/nodes file manually, restarted pbs_server, then run the "pbs_postinstall", now there is no "/opt/pbs/bin/pbsnodes: Server has no node list" message, but still tons of "qmgr obj=node2.cl.hhmi.umbc.edu svr=default: Unauthorized Request" messages from each node. This is my first time playing with PBS, so anyone has any ideas on this, maybe something on nodes have to be done? BTW, I can ssh to any node without password without problem.

If you need to select it manually, then something is wrong. Can you run the following command and paste the output here? Run it 2 times at least: % cd /opt/oscar/packages/torque/scripts % ./post_install also: % qmgr -c "print server" You might also want to check the Torque logs to see what is going on: /var/spool/pbs/server_logs/pbs_server.log Cheers, Bernard =========================================== Yu Chen Howard Hughes Medical Institute Chemistry Building, Rm 182 University of Maryland at Baltimore County 1000 Hilltop Circle Baltimore, MD 21250 phone: (410)455-6347 (primary) (410)455-2718 (secondary) fax: (410)455-1174 email: [EMAIL PROTECTED] ===========================================
