In this documentation, we call golden node the node we want to clone. We can duplicate SCSI or IDE hard drive, and duplication support multiple filesystem (reiserfs, ext2, ext3, ext4, xfs, jfs). - This method came from a very old project called CLIC, and was used under IGGI project, all Mandrake Clustering products, and now it is used under XtreemOS project. Now it should be available in 2010 spring, and all futur product. - </p><p>WARNING: all data on client nodes will be ERASED ! We duplicate partitions of HDD's golden node, and the process will do an fdisk command on the client node, so ALL YOUR DATA will be erased on client nodes.</p><div class="sect2" title="2.1.

KA method only duplicate data on partitions, so if you have 80go HDD disk, and - only 10go on it, KA only duplicates 10go, and not the whole disk.
