Hi Dave,
I looked at our code and found out that we do have problems handling
nfsserver attribute for diskful installation, with service node pool and
without. Basically the error is from the .tmpl file which uses
noderes.nfsserver to define where the source rpms can be found. When
nodeset is called, the .tmpl file is used as the template to generate the
kick start file (which is located under /install/autoinst direcotry).
Anyway, there are two aspect of it:
1. Without service node pool, if the noderes.nfsserver is blank, it should
pick up noderes.xcatmaster. If noderes.xcatmaster is blank, it should pick
up site.master. Currently this logic does not work, I just got it fixed
in xCAT 2.7. The work around for now is to make sure nfsserver is not
blank.
2. With service node pool, the above logic cannot be applied because
noderes.xcatmaster is always blank and at nodeset time, the DHCP server is
not known yet. So, you need to pick a service node from the pool and use
it as the nfsserver. BTW, xCAT has not supported service node pool for
diskful nodes yet. This item need to be added in the future.
Hope it helps.

Hi Ling,
Thanks for your help! Here's the information you requested:
[root@mn ~]# xdsh -V
Version 2.6.9 (svn r10986, built Wed Nov 9 04:49:31 EST 2011)
Management node:
[root@mn ~]# df -h /install
Filesystem Size Used Avail Use% Mounted on
storage01:/install 47G 6.7G 38G 16% /install
Service node:
[root@service01 ~]# df -h /install
Filesystem Size Used Avail Use% Mounted on
storage01:/install 47G 6.7G 38G 16% /install
(Please note that /install/autoinst is symlinked back to /local_autoinst
on each node)
Installloc:
"installloc","storage01:/install",,
I tried following this guide (
http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Setting_Up_a_Linux_Hierarchical_Cluster#Service_Node_Pools
) but have not been able to make both the management node and the service
node generate an /install/autoinst file who's URL points to themselves.
Note that the guide states:
Note: the noderes table's xcatmaster, tftpserver,nfsserver attributes
should be blank for any node entry that has the noderes servicenode
attribute set to a pool of service nodes. site table attribute sharedtftp
should be no or 0.
I have those all set as well, but when set it just complains about
noderes.nfsserver being empty:
[root@mn ~]# nodeset c1n01 install
c1n01: Error: Unable to find requested nfsserver from noderes, with
node=c1n01
Error: Some nodes failed to set up install resources, aborting
c1n01: Error: Unable to find requested nfsserver from noderes, with
node=c1n01
Error: Some nodes failed to set up install resources, aborting
My noderes table:
[root@mn ~]# tabdump noderes

What version of xCAT are you running? (xdsh -V)
Where /install is mounted on the service nodes?
If site.installloc is set? what is it value?

Either this question is too simple that nobody wants to answer it, or I've
stumped everyone :)
Any help is greatly appreciated. Still not able to get this working
properly.

It is my understanding that if you leave "xcatmaster" blank, whoever boots
the node via DHCP becomes that node's xcatmaster. It is also my
understanding that if you leave nfsserver and tftpserver blank, they will
inherit their values from xcatmaster.
What I am attempting to do is set up an environment where whoever boots
the node from DHCP becomes that node's xcatmaster, nfsserver, tftpserver,
and ftp server. I can't seem to get past xcat complaining about nfsserver
being blank however, even when I put an entry in for "xcatmaster". What am
I doing wrong?
Thanks for the help!
