Hi, Just to clarify that I didn't attempt to rebuild the three stateless images, only to use them as is. So I probably don't need to worry about choosing partimage or partimage-ng.
I still stuck at 'Unable to identify plugin for this command, check relevant tables: nodetype.os', any help/hint/suggestion is appreciated.

I cannot find partimage-ng anywhere, so I have partimage-0.6.9 compiled and installed, but it doesn't seem working. I got: [root@blade14 ~]# nodeset blade08 image blade08: Error: Unable to identify plugin for this command, check relevant tables: nodetype.os I have to handcraft several xcat tables, among them nodetype and osimage are the ones I have little confidence. Could you dump some relevant records in those two tables to illustrate your setup? also, do I need to change anything to switch from partimage-ng to partimage?

They are gziped cpio files and are typical linux initrd and root filesystem images. You can do the following to extract them: mkdir /tmp/stateless cd /tmp/stateless mkdir initrd mkdir rootimg wget http://people.apache.org/~jfthomps/partimageng_xCAT2x/initrd.img wget http://people.apache.org/~jfthomps/partimageng_xCAT2x/rootimg.gz cd initrd zcat ../initrd.img | cpio --extract cd ../rootimg zcat ../rootimg.gz | cpio --extract # if you do this last command as a non- root user, you will get one error about not being able to create dev/null which is okay to ignore unless you want to modify and recreate the image You would actually need to go through this process if you have hardware that is not supported in these images. I only had the hardware at NCSU to develop on; so, they don't have a very big range of hardware support. If you decide to go ahead with using this stuff for partimage and need support for different hardware, I can guide you through adding it in to initrd and rootimg. If you wanted to modify and recreate the images after doing the above, you would do the following: cd /tmp/stateless/initrd find . | cpio -oc | gzip -c -9 > ../initrd-new.img cd /tmp/stateless/rootimg find . | cpio -oc | gzip -c -9 > ../rootimg-new.gz The two images really don't do much. Most of the work is done by the partimageng postscript. They really just provide a small install of linux on which the other stuff can run. As long as NCSU is using bare metal images, we'll still need a way to use xCAT and partimage to deploy images, and I don't see us moving completely away from bare metal images for many years. I have been told that more recent versions of xCAT 2 do have partimage support, but that you have to download that part separately. I have not looked in to this, but if it would be easy to switch VCL over to using that, it's possible we may do so in the future.
