How long it takes to finish a 'nodeset osimage> command?
From the syslog, did you see all the nodes get hanging in nextdestiny for a
while before getting into deployment process (10 minutes?)? Or you saw the
nodes got into deployment process one by one with a fixed interval (what
was the interval
There is just 2 tasks, a runimage and an osimage.
chain.currchain=osimage, and
chain.currstate=runimage=http://master/install/script.tgz.
The image is available to be downloaded. A nodeset on a single node
completed immediately.

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.

xCAT is using genesis (an xCAT customized pxe tool) to function the
discovery process. The configuration for genesis is put
in /tftpboot/xcat/xnba/nets/ for a specific network. Could you check your
specific xnba configuration file for your deployment network has been put
in /tftpboot/xcat/xnba/nets
How many tasks in your chain list?
What's the value of chain.currchain and chain.currstate for nodes when you
saw that a lot of processes hang in 'nextdestiny' request?
What I can think of is the 'nextdestiny' will try to check the http
download path of 'runimage', could you check the path is acce
The answer is yes, xCAT does support the otherpkgdir. But the prerequisite
is the 'otherpkglist' must be set otherwise 'otherpkgdir' does not make
sense.
Thanks

The question turns to whether to use the site.precreatemypostscripts. This
site attribute is used to improve the performance of postscript mechanism
in a big cluster.
If site.precreatpostescripts is enabled, the mypostscript for the node will
be generated by nodeset command on xCAT MN. When bootin
The xCAT genimage command is used to create the diskless image, using an
osimage definition to specify how the image is created. Typically, to
change the /tmp partition size, you would write a postinstall script for
your osimage that genimage would call to change your /etc/fstab in the
image.
Thanks Lisa. I figured out what my problem was (see other reply I
sent earlier).
However, there's code in the otherpkgs postscript that is not
following what the script header states:
#OTHERPKGDIR is set only when the provmethod is the os
image name
Took a look at the otherpkgs postscript which runs when you run
updatenode. Look at the header
#=head1 otherpkgs - only runs on Linux
#=head2 It gets the extra rpms and install/update them.
#The environment variable OTHERPKGS contains the rpms to be
installed/updated.
#On MN,
You should also have a diskfull service node image
centos6.4-x86_64-install-service. Normally the service nodes are diskfull
but they can be diskless.

The easiest is just define a node group on the nodes for their rack
location. Then you can use racklocation group names.

Dear All,
We have a customer using PCM 4.1.1.1 and they have some issues with the
size of the default /tmp partition size created by diskless image. (500MB
by default)
There are some scripts that requires larger /tmp size. May I ask if it's
possible to change the the default size from xCat perspe
