#62 Clonezilla live PXE boot do not mount aufs root

[Roberto Nunin]

Scenario:
PIdora latest on Raspberry PI, that act as PXE,TFTP and HTTP server. DHCP is active on a Cisco router, that is correctly configured.

Both clonezilla live stable and gparted live stable, both latest releases.
Boot from PXE seems to work fine, filesystem.squashfs at the end of both boot attempt (clonezilla or gparted) are mounted on loop devices.

What is not working is the aufs mount of filesystem.squashfs in /root/ and ehci-orion loadable module isn't found.

With crtl+c I've access to the limited os commands but attempt to mount filesystem.squashfs end with "No such device" like if the aufs module isn't provided with vmlinuz/initrt that come with the clonezilla/gparted iso's.

Seems strange that both images had the same behaviour.

How I can debug further ?

If the version of Clonezilla live you use is >= 2.4.2-10 or >= 20150608-vivid, aufs is no more. You have to use "overlay", please check this:

Hi Steven

thanks for answering.

After adding union=overlay to the APPEND initrd boot string, I can reach
the first two prompts for language to be used and keyboard mapping.
After that, only blank screen and cursor at position 1,1.
This happen now both in clonezilla and gparted.

Here is my initrd string, from clonezilla website:

APPEND initrd=images/clonezilla/live/initrd.img boot=live config
union=overlay noswap nolocales edd=on nomodeset
ocs_live_run="ocs-live-general" ocs_live_extra_param="" keyboard-layouts=""
locales="" ocs_live_batch="no" vga=799 nosplash noprompt fetch=tftp://
10.117.2.26/images/clonezill/live/filesystem.squashfs ocs_prerun="mount -t
nfs 10.117.2.27:/dev/md1/private/clonezilla /home/partimag"

I've also tried without the attempt to mount the nfs share, without changes.

Can you point me to a debug process ?

BR,
Roberto

Instead of "vga=799", did you try other modes?
Like vga=791, 785?
and add the boot parameters shown on the Clonezilla live syslinux/isoslinux.cfg, i.e.
nosplash i915.blacklist=yes radeonhd.blacklist=yes nouveau.blacklist=yes vmwgfx.enable_fbdev=no

BTW, I suggest you try to boot that machine with some version of Clonezilla live on a USB flash drive, and if it works, copy all the boot parameters from syslinux/syslinux.cfg to your PXELinux config. This will be easier for you to test.

Hi Steven
With the same parameters included in the grub.conf of the live version, it
works fine.
My error was to rely blindly to the website suggestions.

Thanks a lot for your precious hints.
Ciao,
Roberto
