I am a little confused as to why you think xCAT does not provide an image install method. Could you explain further. What is different than the xCAT ability to create and install statefull,stateless and statelite osimages. Sections 6 and later in this doc describe deploying nodes. https://sourceforge.net/apps/mediawiki/xcat/index.php?title=XCAT_iDataPlex_Cluster_Quick_Start
Lissa K. Valletta 8-3/B10 Poughkeepsie, NY 12601 (tie 293) 433-3102 From: geert geurts <[email protected]> To: xCAT Users Mailing list <[email protected]> Date: 03/18/2013 11:00 AM Subject: [xcat-user] rsync image install Hello xCATlist, For our new cluster we were looking for a similar way of node installation as seen on Bright ClusterManager clusters. We asked IBM if xcat featured a image install method, but this was not the case. We have been looking at ways to get a similar solution, but were unable to satisfy this need with the conventional xcat methods available. I decided to try to implement a customized initrd which would rsync the rootfilesystem from a service node to the computenodes. I would like to share this software to the list in the hope it will be useful. It features: * a partitioning layout boot kernel option in the form: "partitionsinfo=/dev/sda1:linux-swap:2000:200,/dev/sda2:ext3:208000:208:/,/dev/sda3:ext3:40000:400:/usr" to specify the required partition layout. * rsync install of rootimage under directory /node-images/default-image using kernel bootoption "image=/node-images/default-image" * both full as update only rsync install * sshd for debuging More complete, documentation as well as the rpm can be found under: https://imaster.hrz.tu-darmstadt.de/dokuwiki/doku.php?id=ibm:rsync_image_installation_of_nodes This docuwiki article refers to an svn directory for the scripts, which is not world readable, but all scripts are in the rpm. When anyone finds bugs or adds features, please send your changes to the email provided in the scripts.
