Hi Tamuka,
This is clearly a boot image problem ☹
Can you tell me where it hangs. Do you see kernel boot messages? Is it able to
start the systemimager script?
The “known” problem is when lvcreate tries to create the volume groups. I think
that building the rpm from rhel6 that uses an old lvm conflict with the boot
image lvm version.
The issue is that the rpm builds on a 2.6.32 running kernel with 2.6.32 sys
includes and old lvm includes, and the image tries (in order to have latest
hardware support) to build a 3.x kernel with a new lvm that is designed to work
with kernel 3.X
Unfortunately, eventhough I did my best to force using built 3.x kernel
includes when building the new lvm it looks like the build still uses rhel6 old
lvm includes and rhel6 2.6.32 kernel includes. Thus the problems ☹
The new approach will be to build the minimum (flamethrower client, bittorent
client, and a few minor stuffs) and use Dracut to create the boot image using
distro kernel (with latest hardware support), distro lvm utils commands, …) and
thus obtain a stable and coherent image that supports latest hardware.
In the meantime, you can trie to extract the image, replace the kernel modules
with running system ones, the lvm utils and libs from running system , recreate
the initrd and boot with the system kernel and see if it helps.
Before doing that, you could try to install using raw partitions instead of
lvm. (the problem waybe before lvm).
Best regards.
PS: My progress so fat on creating the boot image is:
- I can create a boot image by hand for non systemd based systems
- The image boots but fail to start the correct systemimage script
(should be easy to fix). Problem is that the image tries to do a pivot root.
- I need to write systemd side (files that will trigger the install)
- I need to update the initrd make.d build files. Remove all
<component>.rul that exists on the build host and keep only specific stuffs

Objet : Re: [Oscar-users] Status of SystemImager project?
Hi Olivier andJesse
I'm having trouble with tftp for network booting, "PXE 32 tftp open timeout" Is
this related to the problem you just mentioned , I am using Centos 6 and OSCAR
6 as well. I have tried all the solutions I hv found online, but none of them
has worked, thus, disabling firewall, iptables, making sure xinetd and tftp
server are running, putting dhcp and xinetd on the same machine, I also tried
to write the image to a disk and install from there and its hanging before it
goes far,
Is this something i can resolve or its it needs me to wait for the system
imager fix? I am building a small cluster for an academic project and I have
taken longer than I was allowed to to get things running. Is there a quick fix
I can do?
Thank you for your response

Thanks Olivier! This is good timing, actually; I just this morning saw my
latest attempt at an auto install freeze at the first call to lvcreate,
and didn't understand why until I saw your response. UYOK should be fine
for us, and we actually were using custom kernels anyway up until now; I
just thought I'd give the defaults in si_mkautoinstalldisk a try. I'll go
back to our previous boot files and see how it goes. Thanks again for the
quick response.
