Re: [xcat-user] Genesis kernel on Haswell (AND OTHER MISSING DRIVERS AND SUCH)
I figured it out. There is a problem in the code /bin/doxcat that tries to run ntpq command with flag rv 0 state, however, the rv 0 state was removed in the new ntp version. I fixed the problem in code, made a new xCAT-gensis-base based on CentOS 6.5 and uploaded it to sourceforge, if you get the latest xcat-dep and the 2.8.4 xcat-core snapshot build, you should be ok. - Li,Guang Cheng (李光成) IBM China System Technology Laboratory Email: ligua...@cn.ibm.com Address: Building 28, ZhongGuanCun Software Park, No.8, Dong Bei Wang West Road, Haidian District Beijing 100193, PRC 北京市海淀区东北旺西路8号中关村软件园28号楼 邮编: 100193 From: Dan Kulinski dan.kulin...@globalgeophysical.com To: xcat-user@lists.sourceforge.net xcat-user@lists.sourceforge.net, Date: 2014/01/25 05:08 Subject:Re: [xcat-user] Genesis kernel on Haswell (AND OTHER MISSING DRIVERS AND SUCH) Message: 3 Date: Fri, 24 Jan 2014 13:36:48 -0500 From: Jarrod B Johnson jbjoh...@us.ibm.com Subject: Re: [xcat-user] Genesis kernel on Haswell (AND OTHER MISSING DRIVERS AND SUCH) To: xCAT Users Mailing list xcat-user@lists.sourceforge.net Message-ID: of151c7eb5.40b31217-on85257c6a.00663a76-85257c6a.00664...@us.ibm.com Content-Type: text/plain; charset=us-ascii Odd, anything in /var/log/messages?

However, upon boot into either shell or runcmd=bmcsetup I see the following repeated: ***A request variable unknown to the server Interspersed with: FAILED TO RETRIEVE SETTINGS, RETRYING in 15 seconds Is this due to the new genesis image and a mismatch on the xCAT server, running version 2.8.3? I can't figure out what it is trying to reference that is causing this error. Thanks, Daniel Kulinski -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

[xcat-user] Change node IP/hostname without reprovisioning?
Dear All, When I'm searching for a solution to change IP/hostname for a compute node, I've found this article: http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Changing_the_Service_and_compute_nodes_Hostname_and/or_IP The article per se is great for addressing the issue but the solution seems require a reprovision(reinstall) of the node. So I wonder if there's a way to do the same without a reprovisioning?

Re: [xcat-user] Makedns wiping out DNS records
Sorry to revive this, but I have a question about external DNS since I am thinking of trying it now. On the Cluster Name Resolution wiki page ( http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Cluster_Name_Resolution) under 'Option #2: Use a DNS That is Outside of the Cluster' it says: If you already have a DNS on your site network and you want to use that for your cluster node names too, you can point all of the nodes to it. You must ensure that your nodes have IP connectivity to the DNS, and you must manually configure your DNS with the node hostnames and IP addresses. What does it mean that you must manually configure the hostnames and IP addresses? Does 'makedns -e' not do that for you, just like it would if DNS were running locally on the MN itself by just parsing /etc/hosts and adding/pushing it to the (remote) DNS zone files for you? In my case I may even be migrating my existing DNS zone files and /etc/named.conf config onto a new VM and bring up DNS there and just add any new hosts. But I would be surprised if makedns -e doesn't add the hostnames and IPs for you. Can anyone who has used the external DNS option with xCAT speak to that?

Re: [xcat-user] Makedns wiping out DNS records
Also, if I externalize DNS but leave DHCP on the MN nothing has to change in the DHCP config, except changes propagated from xcat via makedhcp, does it? As long as I specify site.nameservers=X.X.X.X as the IP of my external DNS master and update /etc/dhcpd.conf with makedhcp only the domain-name-servers line should change, right? I know that I need to change the MN's resolv.conf to point to the external DNS server too to make this work. Also as thishttps://www.mail-archive.com/xcat-user@lists.sourceforge.net/msg00451.htmlarchived list email suggests I should also make sure the TSIG key for DNS is defined in /etc/named.conf on both the MN and the external DNS server (assuming I allow DNS updates only with the xcat_key signature). Does that mean the MN still needs its named daemon running to push out updates though? Overall, in addition to the things mentioned above, is there anything else that I have missed that will be necessary to do to make external DNS work with xCAT?
