Re: Ubuntu 22.04: problem installing nvidia-driver-525

[Thomas Lange]

Here's the log of an Ubuntu installation using FAI 6 and Ubuntu 22.04
in kvm (no real nvidia HW available)

http://public.cs.uni-koeln.de/lange/ubuntu-fai.log

There's no problem by using the wrong kernel. Have a look at line
9236ff

The installaion ISO was created using https://fai-project.org/FAIme,
and I've selected Ubuntu version and added the two packages

  linux-headers-generic nvidia-driver-525

Maybe this helps

Is 5.10.0-18-amd64 the kernel version, that is running during the
installation? Or is it the ubuntu kernel version inside /target?


Yes, it seems that  5.10.0-18-amd64  is indeed the Debian kernel running 
during the installation:



root@jammysrv:/srv/fai/nfsroot/lib/modules# ls
5.10.0-18-amd64




My guess is that update-initramfs tries to build an initrd for the
wrong kernel version.

Can you just ignore this error, or does the installation aborts?



The installation itself continues but the gpu is not identified when 
booting the installed Ubuntu 22.04:


root@l96:~# lspci  |grep -i nvi
01:00.0 VGA compatible controller: NVIDIA Corporation Device 2507 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 228e (rev a1)

It should create the initramfs in the Ubuntu environment, not in the 
Debian environment...


Thanks!
Andreas

I have been building Jammy (Ubuntu 22.04) systems with FAI for months 
now.

Both physical systems and Xen guests.  I can't answer the question about
the efficacy of Thomas's Jammy basefile because I just use been the
mk-basefile script to roll my own basefiles as needed.  The bottom line
is that building Jammy systems works fine with FAI.

hello -

a few months ago i noticed that most of the ubuntu focal/20.04 machines
that we had deployed were reporting the same machine id (stored in
/etc/machine-id).  i finally circled back and it appears the issue is
that, for an ubuntu basefile, debootstrap pulls in the dbus package
which generates a /var/lib/dbus/machine-id file.  if this file ends up
on the installed node, it overrides the FAI-emptied /etc/machine-id and
results in non-unique machine ids.

i've submitted a pull request[1] to exclude /var/lib/dbus/machine-id
from the basefile but thought i should check to see if this might
somehow be specific to our FAI configuration space/setup.  to others
who have deployed ubuntu: are you experiencing or have you already
worked around this issue?

1. https://github.com/faiproject/fai-config/pull/14


Yes, that one was responsible for very nasty, hard-to-spot networking 
errors with LACP (basically duplicated system IDs all over).


In scripts/DEBIAN/40-misc I commented out the following lines:


## make sure a machine-id exists
#if [ ! -f $target/etc/machine-id ]; then
#    > $target/etc/machine-id
#fi
## recreate machine-id if the file is empty
#if [ X"$(stat -c '%s' $target/etc/machine-id 2>/dev/null)"  = X0 -a -f 
$target/bin/systemd-machine-id-setup ]; then

#    $ROOTCMD systemd-machine-id-setup
#fi


and added these ones:


# Ensure a new machine-id is generated under any circumstances
rm $target/etc/machine-id
rm $target/var/lib/dbus/machine-id
$ROOTCMD dbus-uuidgen --ensure=/etc/machine-id
$ROOTCMD dbus-uuidgen --ensure


Now the machine-id is generated on-the-fly and unique on all hosts.

I would just install debootstrap >= 1.0124 on my machine, because this
version added zstd support. Normally it's easy to install a newer version
of debootstrap because it has no special dependencies.
But I didn't tested this yet.

ymmv, but even in an ubuntu environment i found it easier to use the
upstream packages and a debian netboot.  it does look like ubuntu has
updated FAI more regularly in their last few releases but the focal
version is from Apr 2017. if you want to use the ubuntu packages i
would suggest a newer version.  it looks like jammy will have the
still-current 5.10.3 release with some ubuntu-specific changes:

Re: Ubuntu 18.04: netplan support

[John G Heim]

It' may be worse than you know. Netplan uses something called yaml for 
it's config files. YAML is a newish config language, sort of a 
replacement and/or competitor for XML.  I am no fan of XML, believe me. 
I'm blind, you sighted people think you have it hard editing XML config 
files, try doing it by listening to the code. At the same time, I am not 
looking forward to learning yet another protocol that is essentially a 
programming language for config files.


I understand the drive. Every system has it's own syntax that ammounts 
to a programming language for it's config files. Knowing the syntax for 
bind9 config files doesn't help you one bit when writing a systemd 
config file. Samba uses a syntax borrowed from Windows INI files. About 
the only place I can think of where I didn't have to learn a new config 
file language is with apache and podcast feeds. Both use XML so if you 
understand the syntax for apache config files, you also understand the 
syntax for podcast feed files.


So I don't know what to think about netplan & YAML. Haven't made up my 
mind whether to hate it or love it.

I think the reason I couldn't get it to work was because of a bug in

that I think about it, I believe I worked on it for way more than 10
minutes because I recall doing a file-by-file comparison of the configs
from a regular Ubuntu install and an FAI install and finding no
difference. The files in /etc were identical yet it worked in a normal
install of Ubuntu but not in the FAI install.

I finally just added ifupdown to the packages installed during an
Ubuntu

Now that you've brought it up though, I might give it another try

Re: Ubuntu 18.04: netplan support

[Justin Cattle]

We have quite a lot invested in ifupdown - we won't be using netplan for
servers on bionic.

I know that's not a helpful response, but if you decide not to use netplan
you won't be the only people :)

Re: Ubuntu 18.04: netplan support

[John G Heim]

Well, I pulled a Bart Simpson. I tried for about 10 minutes and gave up.

Bakc with Ubuntu 16.04, I tried modifying the old networking script 
using the ifclass command. If the UBUNTU class was defined, it generated 
a /etc/netplan/10-interfaces file. Otherwise, it ran the old code to 
generate a /etc/networking/interfaces file.


I think the reason I couldn't get it to work was because of a bug in 
NetworkManager. It looked like NetworkManager would neither make that 
interface work nor release it so it could be configured by netplan. This 
was a long time ago and my memory is a little fuzzy but I recall typing 
in network manager commands to try to get it to stop managing the 
interface, it saying it wasn't managing the interface, while at the same 
time, a listing of the interfaces it managed showed the interface. Now 
that I think about it, I believe I worked on it for way more than 10 
minutes because I recall doing a file-by-file comparison of the configs 
from a regular Ubuntu install and an FAI install and finding no 
difference. The files in /etc were identical yet it worked in a normal 
install of Ubuntu but not in the FAI install.


I finally just added ifupdown to the packages installed during an Ubuntu 
install. So I've been subverting Ubuntu's normal network config process 
for years now. I just don't do it the way Ubuntu would normally do it. I 
figure when/if Debian switched to netplan, the FAI developers will 
modify FAI to account for it.


Now that you've brought it up though, I might give it another try when I 
upgrade all of my workstations to Ubuntu 18.10 during semester break in 
January. If I get it to work, I can post a howto here.

Well, I don't know, maybe I made the wrong choice but I had to find 
something updated more often than debian stable.  Maybe I should have 
tried a continuous release distro like debian testing.  If only debian 
hadn't called it "testing". I was in a meeting and said something like, 
"What about debian testing? I know it is *called* testing and they have 
a release they call stable. But testing is a lot more stable than you'd 
think and they really should call stable, hardened or better yet, 
fossilized or something like that."


So that didn't go over too well. I am not the best salesman in the world.

If I was King Of the World, the second thing I'd do, after renaming 
cheesecake to "cheese pie" (it is just so clearly a type of pie, not 
cake), is to rename debian testing to debian stable, and rename debian 
stable to debian hardened.

Creating a basefile using a live ISO is really easy. First you install
the required packages:

# apt-get -y install pbuilder debootstrap

Then you create the basefile:

# pbuilder create | tee /root/pbuilder.log

The '| tee...' part is not really necessary of course, but I like having
a log around in case anything goes wrong.

The base image gets saved to /var/cache/pbuilder/base.tgz. It just needs
to be renamed to CLASS_NAME.tar.gz where CLASS_NAME is the name of the
class you are assigning your clients to. Mind the .tar.gz file
extension. Move the file to the FAI 'basefiles' directory and there you go.

Cheers,

Re: Ubuntu Artful

[John G Heim]

I tried doing a global replace on the  mk-basefile script 
s/XENIAL/ARTFUL/g but when I ran the modified script, it created a 4k 
file that didn't work as a basefile. So then I just copied the Ubuntu 
zesty/17.04 basefile to artful/17.10 and it appears to have worked. An 
installation is proceeding as I write.


But I think that the  documentation on the steps to manually build a 
basefile would be helpful. I don't suppose you still have that 
documentation for installing ubuntu around do you? All I remember is 
that it suggested booting from a live Ubuntu ISO and then running 
pbuilder. It doesn't look as if mk-basefile uses pbuilder though which 
confuses me.

Re: ubuntu 16.04 with wheezy nfs-root --> kernel panic

[Sebastian Schmidt]

> Is the nfsroot also a wheezy one?

I was assuming, creating one in wheezy creates a wheezy nfsroot? Your
question now tells me that's not the case? I'm also not sure which
setting influences this. In the nfsroot.conf I configured
FAI_DEBOOTSTRAP as xenial one. I created the nfsroot with fai-setup -vl 
and configured everything to point to xenial, so I think I created a
xenial nfsroot.

I added "deb http://fai-project.org/download wheezy koeln" to my

I'm not using dracut (at least I think I'm not using it). At least I
didn't include it in my NFSROOT-config:

PACKAGES aptitude

nfs-common fai-nfsroot module-init-tools ssh rdate lshw rpcbind
rsync lftp less dump reiserfsprogs e2fsprogs usbutils
hwinfo psmisc pciutils hdparm smartmontools parted mdadm lvm2

PACKAGES aptitude AMD64

linux-image-generic live-boot


> boot=live is not yet used/supported in recent FAI versions any more.
> So this may be your first problem.

I removed it and the kernel panic disappeared! But other errors
appeared now:

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /run on /root/run failed: No such file or directory
run-init: opening conole: No such file or directory
Target filesystem doesn't have requested /sbin/init
run-init: opening console: No such file or directory
...
No init found. Try passing init= bootarg.


I think something is wrong with the folderstructure. He looks
for /root/dev and stuff like this but the correct path
is /root/live/filesystem.dir/

you're trying to get xenial to work as the nfsroot?  i spent a while on
that, too, and think i got to about the same point.  iirc, as suggested
by a launchpad bug, i found the package(s) that depended on
initramfs-tools and rebuilt to depend on linux-initramfs-tool instead
(which dracut Provides).  but once that was done it turned out that
(again, iirc) ubuntu's initramfs management didn't actually work
w/dracut in place.

at that point i gave up and went with a jessie nfsroot.

For what it's worth, I've had pretty good success installing 14.04 clients
from a 12.04 server using the 4.1.1 testing PPA (the nfsroot is
14.04-based, with the default Ubuntu 3.13 kernel). I'm using a live-boot
setup since the dracut packages seemed to be broken in 14.04 when I built
the packages for the testing PPA.

I haven't had a chance to upgrade the FAI server to 14.04 since it's in
production, but I'll try to report back here after I try that.

I initially had trouble with 14.04 nfsroots on FAI 3.4.8 since some system
utilities had been moved/renamed (dpkg-divert comes to mind) -- but it's
been pretty smooth sailing since installing 4.1.1.

Try adding rdshell rdinitdebug rd.debug to the kernel command line.
Makes the booting slow and produces enormous amount of output (at least
under Debian) but may help to pinpoint the part of booting process where
the error occurs.

In the past, for debugging of initrd problems, I have also created

First question: Which FAI version are you using?

 first reboot of the newly installed host, I get an ugly kernel panic:

 Begin: Running /scripts/init-bottom ... done.
OK, you are using initramfs-tools and not dracut. But that's fine for
Ubuntu.

 But if I switch to the 14.04 base.tgz image, using the otherwise the
 same config [1] and the same disk layout [3] (using LVM), the kernel
 chickens out.
For installing Ubuntu 14.04, you are using the Ubuntu 12.04 nfsroot? Is
that right?

Please try to do an Ubuntu 14.04 installation without lvm, but just a
plain simple disk layout. That way, you can make sure if lvm or
something different causes the problem.

Hi. It could be you're running into a feature, where the Ubuntu
installer sees that it's running on an NFS root, and therefore opts to
not configure the network interfaces. If you do, I've run into the
same issue before, and resolved it with a preseed script as described
in this thread:

In short, I add the following parameter to the kernel command line

Re: Ubuntu natty setup-storage questions

[Michael Tautschnig]

Hi Andreas,

Sorry for the delayed reply.

 
 Again me with three issues I asked some time ago already...
 
 a) setup-storage leads to a different partition table than
 setup_harddisks, although the disk_config file only changed in
 syntax.
 

This is expected as alignment constraints were updated and the entire code has
been rewritten, including the bit that computes partition sizes.
Preserve+always_format are the only way to fully retain an old layout.

 b) I'm currently using two classes NO_SCRATCH (for a standard
 partition layout that all of the FAI clients are using) and SCRATCH
 (to preserve a possibly existing /scratch partition that I created
 by hand earlier on some of the FAI clients, but not on all of them).
 
   b 1) How could theses classes NO_SCRATCH and SCRATCH be merged in one
single class? Is it possible at all?
 

When merging these into a single config file, would you also expect that no
scratch partition be created if none exists? Preserve-if-exists is possible, but
don't-create-if-not-there is not possible with current setup-storage. More
details on that below.

[...]
 
 I'd like to merge these two classes if possible.
 
 Is there a way to preserve a partition of  unknown size and unknown
 starting point, but only if it does exist already? I'm doing initial
 installs (fai-chboot -IvBk nouveau.modeset=0 fai_client), but still
 would like to preserve /scratch. I think 'preserve_lazy' is doing
 more than just preserving the partition.
 

What exactly do you mean by doing more than just preserving the partition? In
my opinion preserve_lazy is exactly what you want, except for the fact that it
will always create such a partition in those case where it didn't exist before.

 
 And, secondly, the disk_config file leads to an error:
 
 root@faisrv:/home/fai/l28/last# more format.log
 Starting setup-storage 1.3
 Using config file: /var/lib/fai/config/disk_config/SCRATCH

 Command had non-zero exit code


[...]

I believe that these problems should already be fixed in 3.4.8 (a bug in
computing partition sizes), which unfortunately isn't in Ubuntu. Could you
please give (a) the 3.4.8 packages from Debian a try and, if still failing, (b)
the experimental builds?

Thanks a lot,

What is your goal?

a) Do you manually decide which class applies for each host and want to

b) Do you want to clean up/consolidate your config space and want to
handle /scratch as a special case of NO_SCRATCH?

The answers would be different. a) would hint at some decision logic in
class/ which automatically announces the correct class. b) would require
either modifying your layout-files on the fly or change the way
disk_config works.

Everything's possible. We just need to find the right hammer for your

Currently I'm using the following script to decide whether a client
does already have a scratch-partition or not:

root$ cat FAI/class/30-detect-scratch-partitions
#! /bin/bash
# detect whether a scratch partition /dev/sda3 already exists
size=`fdisk -s /dev/sda3 2/dev/null`
if [ ! -z $size ]; then echo SCRATCH ; else echo NO_SCRATCH; fi
exit 0


I'd prefer a single setup-storage layout file that automagically
detects and preserves an already existing partition. It seems that
the current setup-storage

a) changed behaviour concerning cylinder boundaries compared to
   setup_harddisks 

b) offers different methods how to preserve partitions, but none of
   them seems to fit my case (or I misunderstood the manual, that
   might be the case, of course...).

c) gives a simple error, which should not happen. Or my layout file
   has an error that I don't understand...

Re: Ubuntu natty setup-storage question

[Michael Tautschnig]

Hi Andreas,

Sorry for the delayed reply.

Would you also have the exact disk layout available *before* you did this
installation run? That would help me reproduce the problem/verify that it's been
solved already by some later patch (which is likely as parts of this
size-computation code have been rewritten since).

[...]
 Here the disk_config/SCRATCH file:
 
 root@faisrv:/srv/fai/config/disk_config# cat SCRATCH 
 # example of new config file for setup-storage
 #
 # type mountpoint size   fs type mount options misc options
 
 disk_config disk1 disklabel:msdos bootable:1 fstabkey:uuid preserve_always:3
 primary  /1ext3  rw,noatime,errors=remount-ro
 logical  swap  2000swap  rw
 primary  /scratch  0-  ext3  rw
 
 
 I.e. if already existing, the /scratch partition is supposed to be
 preserved, otherwise it should be created.
 
 Any idea?
 

First of all, that's not quite the semantics of preserve_always; preserve_always
will require that the partition already exists. You want preserve_lazy, it
seems.

 And why does parted want to start the first partition at 32256B?
 (bad performance?)
 

That was the previous default, i.e., sector 63 as MSDOS did. We're new moving to
1MB, which should be better, but this is only part of experimental FAI packages
right now.

Best,
Michael

I don't think so, it's political. Ubuntu and Debian do have several
differences between the two distros.
That's a normal divertion between the two.

Honestly, on Ubuntu the fai packages are changed in some ways, like
NFSROOT dependencies Ubuntu doesn't have, or named differently.
So having some special treatment for the package doesn't cost money.

 apt-get. But my suggestion would be to do this in the Debian packages.

I think Thomas had something in mind to default to aptitude. I don't
know why.
But if it works when you replace aptitude with install, we are a step
further to a good FAI package in Ubuntu :)

Anyways, I'm trying to find the changelog of debootstrap to not install

we normally debootstrap with variant -, so in the squeeze script we get

if doing_variant - || doing_variant fakechroot; then

 You'll want to make sure that your exports file matches what is in the

Re: Ubuntu 10.04 TFTP Error - File Not Found

[David Dreezer]

I can't help you there as I've never used Ubuntu 8.04, as we're on Debian here. 
 10.10 is current Ubuntu release, AFAIK.  

You'll want to make sure that your exports file matches what is in the NFSROOT 
in make-fai-nfsroot.conf. Edit it manually if you need to, then restart 
nfs-kernel-server.  If you need to make any adjustments to 
make-fai-nfsroot.conf be sure to run fai-setup again.

Re: Ubuntu 10.04 TFTP Error - File Not Found

[David Dreezer]

Make sure that /etc/default/tftpd-hpa has the correct directory, first off.  It 
will need to match what you have in /etc/fai/make_nfs_root.conf. Then edit 
TFTP_OPTIONS to include -v -v -v (all in lower case)  That will make tftpd 
write to your syslog so that you can read the log and see what the client is 
doing and where the server is trying to serve the files from.

You might also try man tftpd: http://linux.die.net/man/8/tftpd

Re: Ubuntu Universe Freeze for Ubuntu 10.10.10

[andrew bezella]

hello -

i sent this to f...@sourcecode.de about a month ago, so apologies if it's
already been addressed.  i'm using 3.3.5ubuntu3 but the errant line
still appears in 3.4.2ubuntu1 from maverick.

i noticed that there is a minor glitch in fai-setup.  when it creates
the known_hosts for the loguser and live filesystem it does so
incorrectly.  instead of adding the server's ip address, it uses the ip
address/subnet mask (e.g., 207.241.226.106/21 ssh-dss [...] instead of
207.241.226.106 ssh-dss [...]).  for me this prevented the closing ssh
requests to the fai server from working by default.

there is a similar (correct) snippet of code in make-fai-nfsroot and i
made a simple tweak to fai-setup to match that.  it appears to fix the
problem.  patch file attached.

thank you for your time and effort in making fai available for ubuntu.

andy

Re: Ubuntu FAI PPA and Lucid Lynx - Lucid Host

[Robert Markula]

On to the task of installing Ubuntu 10.04 (instead of Debian Lenny) on
the target host.

I've once again used the vanilla PPA packages (3.3.5ubuntu3) without any
modifications except the following:

# First, I've edited the /etc/fai/make-fai-nfsroot.conf to set the
following option:

snip
FAI_DEBOOTSTRAP=lucid http://archive.ubuntu.com/ubuntu;
/snip


# Then I've edited /etc/fai/apt/sources.list to look like this:

snip

deb http://ppa.launchpad.net/fai/ppa/ubuntu lucid main
/snip

This works basically (in the sense that FAI does it's job) and the
host gets installed. However, I'm currently stuck with the host booting
straight into Memtest86+. Upon looking through the fai-setup.log [1],
I'm a bit worried by the line:

snip

The full fai.log is at [3].

I'm sure it's just some small config error I've overseen with my tired
eyes. Maybe someone has an idea what could be the reason that obviously
no kernel gets installed? I'm going to bed now.

Re: ubuntu installation just like from DVD Installer

[Thomas Neumann]

 I would like to ask how other FAI-Ubuntu-admins are doing it:
 Do you have custom package lists?

Yes

 Do you care that some configuration differs from a normal ubuntu
 installation? e.g.

No.

The reason is, that I see vendor install as a starting point. Every
distributor (hopefully) tries to guess really hard, what their intended
userbase might need and what not - but ultimately it's a futile attempt.

I specify the stuff I really want and let FAI figure out which required
packages have to be installed in order to get there. (Works pretty well
for Debian and Ubuntu, SuSE is a bit more tricky.)

Re: ubuntu installation just like from DVD Installer

Hi Patrick,
Patrick Cervicek wrote,

 I am installing Ubuntu Karmic with FAI and it works. No problems so far.

 From time to time I recognize that some packages are missing. Packages, which
 would be there if it would be a normal DVD Installation.
 To get this normal packages in my ubuntu I have to put them in my 
 KARMIC-Packages-List. Examples:
   software-center
   jockey-gtk jockey-kde # Hardware Drivers/ Proprietary drivers

 I tried already several metapackages e.g. apt-get install ubuntu-desktop 
 but there are still packages missing.
 I know, I could do an tarball but then I would need to change too many  
 preconfigured values.

The trick is to use aptitude-r with the meta-package ubuntu-desktop.
After that you nearly get a CD/DVD like installation. Only the
special language files may be missing. And if you use FAIBASE, you
get some extra packages installed for fai client.

Re: Ubuntu FAI behind ftp_proxy (squid)

[mettler]

hi,
Thanks alot Carsten,
We are serving some commercial software via password protected ftp and
can't give it away  - so there are several policies involved ;)

Thoughts about mirroring them via http are emerging ;)
But that will take some time.




The questions is:
When I use /etc/environment or /etc/bash.bashrc to export
environment-variables INSIDE the chroot they are not always respected when
using $ROOTCMD or using install_packages.


What would be the right place to put these?
How to set up an environment variable that will be used by install_packages?


Or how to modify the install_packages' $root_cmd without editing the
script itself? if there is no other way.




Regards!
Stephan

 I tend to think to stand up an http server for those should be easy, but
 then I don't know if you administer these servers yourself.

 What I would do is to mirror those packages into a private repo whcih
 you can thn access directly via ftp or http if possible. But then I
 don't know what kind of policies are other problems might stop you from
 doing that.

Re: Ubuntu 9.04 Jaunty FAI howto

[Stephan Hermann]

Hi Robert,

thx for your documentation on how to setup FAI on an Ubuntu Server
Host :)

Well done...

I have one fix for your documentation:

in hooks/updatebase.OS_UBUNTU_904_X32 you write something like this:

# Import FAI repository keys
echo Importing FAI repository keys
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com AB9B66FD


Most likely that this won't work in a production environment because
normally during setup you don't have internet connection (at least at
our place here, and in most Datacenters I was using FAI).

Normally you should prepare your own Package archives locally (not
using apt-proxy but some debmirror magic) so you can mirror the fai
koeln packages from uni-koeln.de

Btw...would you like to work with us on FAI in Ubuntu?

We need to adjust some values in MrFai packages for Ubuntu to not
change that much on the first installation.

Re: Ubuntu 9.04 Jaunty FAI howto

Hi Stephan,
you are right, and thinking about it, this isn't needed for this FAI
installation anyway, as FAI_ALLOW_UNSIGNED is set to true in BC_BASE.var.

I'll correct it on the wiki.

Using apt-proxy instead of debmirror was done just out of simplicity.
IMO it serves the purpose of this howto (setting up a testing
environment) very well.
If it's about using FAI in production environment, I don't have as much
experience as you do. Maybe we should add a note to the wiki? Or
describe an alternative approach in detail?

 Btw...would you like to work with us on FAI in Ubuntu?
I'll contact you off-list.

 Since it is my first FAI howto, I hope I did not violate any rules. I'd

It really looks quite good, but yes, I have some hints about possible
improvements that come to my mind when skimming over it:

What you should mention is, that this is also a Howto for getting FAI up
and running on an Ubuntu Server! I didn't try that myself for a long
while, but from thinghs I read in the list and IRC I was thinking FAI
server support is broken in UBuntu.

I don't exactly understand the part  Activate routing - it might be
very specific to the way you build your testing network,
maybe you should describe the whole network setup you assume to be used.

And, very last, some parts (especially the explanations and listings of
party of the configspace) look like these are things that are already
described in the configspace - maybe it could be made shorter by just
linking to other docs.
I might oversee that you show only things specific to your Ubuntu setup
- in that case, forget that remark :)

 Also, as mentioned in the WIKI, due to the lack of physical machines, I
 was only able to test this in a VirtualBox environment. It should work
 in a 'real' environment nevertheless, but here I depend on your feedback.

I'll not come to really test every step out, but usually, things whould
work very similar if you connect the cables the same way as the virtualy
machines are attched top each other...

As you don't say which version you are currently running, I cannot say that.

If I recall correctly, in terms of your multi-distribution goal, there
are no big changes between the normal Etch version and the latest
release that was built for Etch on the FAI apt repository.

But upgrades to Lenny will be easier if you start using the newer
version now.

debian32, debian64, ubuntu32 and ubuntu64 all get installed from the

creating the NFSROOT (and therefore the boot CD) under Feisty but
putting the Gutsy installation base in it, but it's not a clean way to
do it. My method is explained in more details here :
http://staz.be/wiki/FAI_GUTSY
(sorry I promised to migrate the HowTo to the FAI Wiki but still hasn't done so)

 It seems that the unionfs delivered with hardy does not allow the
 client to change/append to existing files at all whereas creating new
 files is no problem...

This is not correct.

You need to have /var/run created before anythin else...
this is only needed for some services during startup.

And yes, you have to create it if you don't have it.
Using an ubuntu chroot it actually have it...for others, it needs to be
created before hand :)

After that, you can mount /var and /var/run to whatever partition you
want.

 I've had a struggle with that one too..
 
 My hack was quoted on the list, see bottom half of:
 
  https://lists.uni-koeln.de/pipermail/linux-fai/2007-June/005031.html

The easiest solution is to use a ubuntu base tarball as base.
The other solution is to create those directories after partitioning
and mounting.

Maybe for you too http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=444079
applies - please try to add nfs-common to the NFSROOT file (as shown in the
patch attached to the bug report).

Best,
Michael

  

nfs-common already is in nfs root.
and it doesn't work...

I try to understand one thing:
- When a fai client boots up, he try to mount the nfsroot in read only. 
all the data is written somewhere else using tmpfs. Is that right ?


If this is true, it may be a problem with tmpfs wich is not doing is 
job (or not present, or not configured...) ?

There are parts that need to be written on every boot-up, just temporary things.
Prior to live-initramfs this was solved by mounting parts of the file system as
tmpfs. Now live-initramfs takes care of everything.

You definitely need to debug the mount problem, possibly by checking the logs on
the server.

HTH,
Michael


  

Taking a look at this old message, i found this:

I don't really understand what's going on.
Maybe FAI tries to umount an nfs directory that does not exists ? (here 
/root)

But rpcinfo -p says that rpc is running




AFAIK this is just fine, for whatever reason it comes up, but I think things
should work nevertheless.

So -- what's your current status? What does work, what does not?

Best,
Michael

  
A this time I get a PXE boot on kernel + initrd (2.6.22-14, but it does 
the same with olders).
Then if I define /srv/fai/nfsroot as NFSROOT it goes on an endless loop 
reporting:


Nov  9 10:00:41  mountd[9249]: authenticated mount request from 
:840 for /soft/fai/nfsroot (/soft/fai/nfsroot)


Nov  9 10:00:41  mountd[9249]: refused unmount request from 
xxx.xxx.fr for /root (/): not exported


In /var/log/daemon

In a second way if I define /srv/fai/nfsroot/live/filesystem.dir as 
NFSROOT (I now this is wrong, but for testing), there is no endless loop 
but FAI does not  work saying that the filesystem is read only.

I have no idea who is trying to unmount something here (note that you replaced
parts by very different x-combinations). But I think FAI will never try to
unmount anything just after it mounted the root fs. It's all pretty strange...

Sorry, no idea so far...
