Hi Ubuntu Team,

We are using Physical server and are in process of Automated
“ubuntu-12.04.1-server-amd64” OS  installation on it.

There are two HDD for OS installation purpose and there are RAID1 relation
between them. This setup has been done through BIOS.

The kickstart configuration file looks like this:

#Generated by Kickstart Configurator

#platform=AMD64 or Intel EM64T

#System language

lang en_US

#Language modules to install

langsupport en_US

#System keyboard

keyboard us

#System mouse


#System timezone

timezone Asia/Dili

#Root password

rootpw --iscrypted $1$Yl1QJyta$KzIT.kq3i9E5XaiQKcUJn/

#Initial user

user ankit --fullname "Ankit" --iscrypted --password

#Reboot after installation


#Use text mode install


#Install OS instead of upgrade


#Use Web installation

url --url

#System bootloader configuration

bootloader --location=mbr

#Clear the Master Boot Record

zerombr yes

#Partition clearing information

clearpart --all --initlabel

#Disk partitioning information

part /boot --fstype ext4 --size 100 --ondisk sda

part / --fstype ext4 --size 10000 --ondisk sda

part /var --fstype ext4 --size 10000 --ondisk sda

part swap --size 1024 --ondisk sdb

#System authorization infomation

auth  --useshadow  --enablemd5

#Network information

network --bootproto=dhcp --device=eth0

#Firewall configuration

firewall --enabled --trust=eth0 --http --ftp --ssh --telnet --smtp

#X Window System configuration information

xconfig --depth=8 --resolution=640x480 --defaultdesktop=GNOME

But I am getting the below error : "No root file system is defined"

Please suggest on this. Do we need to do any modification in kickstart
configuration file.

Any help in this regard will be very helpful for us.

The automated Ubuntu OS installation is successful in Virtual Machine(VM)
with the above ks.cfg (kickstart configuration file ) but failing in case
of physical machine.

Please suggest on this and if possible provide the new ks.cfg file to
resolve above problem.

Thanks & Regards,

Rajesh Prasad
