Re: Regarding NFS method of Installation issue in RHEL 6.6




Hi Vratislav, All,

Thank you for responding.
I am providing you  more details:-

Regarding booting the Installer

1. I am using network boot and for that I am using RHEL suggested method as below:-

1. Copy the vmlinuz, initrd.img and pxelinux.0 to /var/lib/tftpboot/pxelinux.cfg
2. Create a default file that contains option to boot above kernel vmlinuz and initrd also with ks        parameter to pass nfs location of main kickstart file 
3. Mount the ISO on server and copy its contents to the directory.
    The directory has below folder:-

    Packages --> contains packages
    EFI   --> contaings BOOT directory
    isolinux --> contains isolinux.bin vmlinuz initrd.img
    images  -> contains install.img efidisk.ing pxeboot directory 
    repodata  ->  containing comps.xml
    kickstart   --> folder containing all kickstart files

4. Export this directory via NFS.
    

5. After that the client system is booted over network (PXE boot)
6. After that Running anaconda  message appears.
7. After the screen of running anaconda , below error occurs:-
 
>Unable to open input kickstart file: Could not open/read
> file:///mnt/stage2/kickstart/Additional.inc

I am providing you snippet of kickstart file as below:-


install
nfs --server=169.254.1.2 --dir=/export/home/agarg/imag

key --skip
lang en_US.UTF-8
keyboard us

% include /mnt/stage2/kickstart/Additional.inc

%packages
@base
@supp
@core
%end


Also I want to confirm an additional query:-

Also there is a pre section in my additional kickstart file which is Additional.inc which is used to probe for system related information and store it in a file.

But I think that %pre script execution from additional kickstart file has been removed, can you please confirm.
Does In RHEL6.6 installer does %pre section script executes only from the main kickstart file and not the additional included files ?

>> Try running
>> $ ls /mnt/source

I checked the above but this directory is not present, only below two directory is present:-

mnt/stage2
mnt/runtime

and mnt/stage2 contains only contents of /export/home/agarg/imag/images directory which are below:-

install.img
efidisk.ing
pxeboot directory 

i will appreciate any further help provided.
Please let me know in case you require more information.

Thanks and regards,
Anant garg

Where is the main kickstart downloaded from?

Can you please add the information on how you boot the installer and how
your kickstarts look?

Try running
$ ls /mnt/source

And see if that's the directory your additional ks file lives in or not.
