diskless environment

linuxtolinux — Mon, 19 Dec 2005 09:27:43 GMT

hello,
i am configuring a diskless environment on redhat entreprise 3.
i did all the necessary configuration concerning the dhcp,tftp and nfs servers as mentioned in redhat administration guide.
i have already configured a network installation using kicstart and everything went very well.
now i am confused about the process concerning the diskless environment: i don't know how to configure my pxelinux.cfg/default.

This was the default file for may network installation:
default rhel3
label rhel3
kernel rhel3/vmlinuz
append ksdevice=eth0 console=tty0 load_ramdisk=1 initrd=rhel3/initrd.img n
etwork ks=nfs:193.100.200.200:/home/pxeboot/diskless/ks.cfg

how could i make it suitable for diskless environment?

thanks in advance

You need to specify that the rootfs is mounted as /dev/ram.

append ksdevice=eth0 console=tty0 load_ramdisk=1 initrd=rhel3/initrd.img n
etwork ks=nfs:193.100.200.200:/home/pxeboot/diskless/ks.cfg prompt_ramdisk=0 ramdisk_size=20480 root=/dev/ram

Regards,
Sergejs
