Thanks!
It is working fine now that I figured out what the issue is. We will
gain a lot better performance with site.precreatemypostscripts
enabled, so we wish to keep it on. This is a cluster with ~6000
nodes.

If site.precreatpostescripts is
enabled, the mypostscript for the node will be generated by
nodeset command on xCAT MN. When booting of node, the created
mypostscript will be copied to compute node directly for
using. The advantage is it can save the computing resource of
MN during the node booting process, the shortage is you must
run nodeset for each changing which related to postscripts.
If site.precreatescripts is
disabled, nodeset command won't do anything for mypostscirpt.
When booting of node, it will try to require the xCAT MN to
generate the mypostscript at that time.
So for your issue, you can try
to disable the site.precreatemypostscripts and to see whether
it works well.
Thanks

I figured out what's going on - we are
using the site.precreatemypostscripts=1 option. Even though the
man page on the site table states that the mypostscript file for
the node should be updated when an updatenode is ran as all as a
nodeset, this is not happening. I have to do a nodeset on the
node to have that file updated.
There's also a gap here in that since the node utilizes it's
local /xcatpost/mypostscript for pulling in variables that the
otherpkgs script needs, specifically $OTHERPKGDIR and
$OTHERPKGS1, you need to reboot your node or manually push the
new copy of this file to the nodes for your changes to
OTHERPKGDIR in the osimage to be seen by your node. In my
opinion, enhancements to updatenode need to be made so that:
A) updatenode rewrites the mypostscript file to capture any
changes you may have made to your osimage definitions
and
B) updatenode pushes this new mypostscript file to the node so
that updatenode will be aware of any osimage definition changes.

Well, genimage seems to pick up my

the temp yum.conf that is created during otherpkgs time with

We are wanting to separate out the otherpkgs based on image
name. Being able to configure otherpkgdir is a good feature
that seems to work fine during genimage time - I would highly
encourage you guys continue with this feature and push it to
the otherpkgs postscript.

Take a look at this documentation , the otherpkgdir always
ends with the architecture directory and then the directories
under that contain the rpms. I have never seen anything
different so this may be a limitation in our code.
In other words in your case it should be otherpkgdir=/install/post/otherpkgs/centos5.4-new-kernel/x86_64

xCAT ignoring my otherpkgdir setting
Hi all,
I am manually setting my otherpkgdir for an osimage that a
node belongs to. However when running "updatenode $node -S",
the setting is being ignored. The problem is bolded below.
Example is below, how do I get this thing to look at the right
path?
