I have two disks (sda and sdb). I have a running Ubuntu 14.04 in sda1. I've cloned sda1 in sdb1 with Clonezilla, so in sdb1 I have too another Ubuntu system, which I want to boot only through the LAN. To do so, I'm using sda1's Ubuntu as PXE/NFS server.

To achieve this, I've done these steps:

1.-I've installed in sda1's Ubuntu all PXE stack (dhcpd,tftp, pxelinux.0) and it just works

2.-I've edited sda1's Ubuntu's /etc/fstab file adding this line (where /mnt/pepe already exists):

/dev/sdb1 /mnt/pepe auto defaults 0 0

3.-I've edited sda1's Ubuntu's /etc/exports file adding this line:

/mnt/pepe  *(rw,no_subtree_check)

4.-I've edited sda1's Ubuntu's pxelinux's default file adding these lines:

    MENU LABEL Ubuntu
    KERNEL vmlinuz
    INITRD initrd
    APPEND netboot=nfs nfsroot=,rw

where previously I've added to the initrd file the ability to work with NFS shares (as it is said in https://help.ubuntu.com/community/DisklessUbuntuHowto#Creating_your_NFS_installation). In detail:

1.-I've created a jail in sdb1 system and I've entered into it:

mount -o bind /dev /mnt/pepe/dev mount -o bind /sys /mnt/pepe/sys mount -o bind /proc /mnt/pepe/proc chroot /mnt/pepe

2.-Inside the jail I've edited /etc/initramfs-tools/initramfs.conf file to have these lines:


3.-I've created the initrd I'm using with:

mkinitramfs -o initrd

4.-I've exited from jail and copyed intrd file to the correct location inside tftp folder.

Nothing more.

What I see when I boot a network client is, lots of error messages like this:

"Retrying nfs mount...Begin: Running /scripts/nfs-premount ...done. mount: Stale NFS file handle"

until I've stuck in a Busybox shell.

I don't know what can I do more. Help please! Thanks!!!!
