Thanks,

I got a	 problem with the ramdisk mounting for a diskless.
I just tried with this /etc/beowulf/fstab:

    /dev/ram1		/		ext2	fs_size=65536	0 0
    none		/proc		proc	defaults	0 0
    none		/dev/pts	devpts	gid=5,mode=620	0 0
    $MASTER:/home	/home		nfs	defaults	0 0

And here is what I got in /var/log/beowulf/node.0:
