Hi Marcelo: That is very strange - can you post your image's /etc/systemimager/autoinstallscript.conf?

Looking for partition table of the nodes, something curious is that there is no swap partition. The file in the systemimager directory and ${OSCARHOME}/oscarsamples/ide.disk say that /dev/hda5 should be the swap partition (id 82). Thanks for your attention ==================== Node partition table ====================== [EMAIL PROTECTED] ~]# fdisk /dev/hda The number of cylinders for this disk is set to 4863. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/hda: 40.0 GB, 40000000000 bytes 255 heads, 63 sectors/track, 4863 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 3 24066 83 Linux /dev/hda2 4 4863 39037950 5 Extended /dev/hda5 4 19 128488+ 83 Linux /dev/hda6 20 4863 38909398+ 83 Linux ==================== Node partition table ====================== ==================== ide.disk ====================== [EMAIL PROTECTED] ~]# more /opt/oscar/oscarsamples/ide.disk /dev/hda1 24 ext3 /boot defaults /dev/hda5 4096 swap /dev/hda6 * ext3 / defaults nfs_oscar:/home - nfs /home rw nfs_oscar:/opt - nfs /opt rw [EMAIL PROTECTED] ~]# ==================== ide.disk ====================== ------------------------------------------------------------------------- Using Tomcat but need to do more?
