This article explains how to initialize a new NFS image.
Contents
Requirements
NetBoot kernel
By now you should already know and have a NetBoot kernel.
!! Don't forget to backup the kernel's libraries and modules !!
>> See TFTP server manage netboot kernels
NFS image folder
You should create a folder to host the new NFS image, for instance QA:
mkdir -p /nfs/qa
chmod -R 777 /nfs/qaThis folder must be registered in NFS server configuration (/etc/exports).
>> See NFS server
Get a minimal Operating System
Go to your NFS image folder (it should be empty):
cd /nfs/qa
Thank to Deboostrap you can initialize a lot of *Nix versions!
You need to adjust the following command to the distribution you'd like to run:
## Debian 7
debootstrap wheezy /nfs/qa
## Ubuntu 14.04
debootstrap trusty /nfs/qa
!! This step is quite long... Depending on your network and CPU it can take up to 10 or 15 minutes !!
Copy kernel's libraries and modules
First thing to do is to copy your kernel's libraries and modules into your new NFS image.
cp -r /tftpboot/sources-images/trusty/lib/modules /nfs/qa/lib/
cp -r /tftpboot/sources-images/trusty/usr/src/ /nfs/qa/usr/src/
Where:
- /tftpboot/sources-images/trusty is your TFTP kernel name
- /nfs/qa/ is your new NFS image
