Re: initramfs on experimental fai-cd
Putting this in config/scripts/FAIBASE/50-mkinitrd is all I needed.
Apparently I over-complicate things
#! /bin/bash
error=0 ; trap "error=$((error|1))" ERR

initramfs on experimental fai-cd
I am trying to make a custom fai-cd using the experimental builds.
Basically I booted a virtual machine from the gnomehost template using the ISO:
http://www.informatik.uni-koeln.de/fai/fai-cd/fai-cd-3.2.16.iso
and then updated it to 3.2.23~beta25+experimental1, and then ran fai-setup,
fai-mirror, and fai-cd, rsynced the 3.2.16 configs into /srv/fai/config
first. (specifics: http://gist.github.com/219822 )
so basically I have 4 environments I'm using to bootstrap the target system
(well, 3 since my workstation is just a host)
workstation
|
+-> gnomehost
|
+-> fai-cd (installer/livecd)
|
+-> target-system(chrooted during install)
If I partition with LVM, (the simple-lvm example from the fai wiki) and let
the installer run update-initramfs from the chrooted-install, it results in an
initrd that will time out waiting for the Root FS (even if I generate it
from another tty after the install, and first add dm-mod to
/target/etc/initramfs/modules )
If I try to create one from the installer (livecd) environment, I get:
"update-initramfs is disabled since running in a livecd"
If I create an initrd in the gnomehost environment using:
TARGETVERSION=$(ls /srv/fai/nfsroot/live/filesystem.dir/lib/modules)
chroot /srv/fai/nfsroot/live/filesystem.dir\
/usr/sbin/mkinitramfs\
-o /srv/fai/nfsroot/live/filesystem.dir/boot/initrd.img-${TARGETVERSION} \
${TARGETVERSION}
And cp it from /boot /target/boot, at install time (overwriting the one the
installer created) the system boots fine.
un-packing the initrds shows some signifigant differences:
(specifics: http://gist.github.com/219803 )
So my question is:
"Is there a trick to getting the chrooted target envronment to create a
workable initrd that I am missing, or am I going to have to create the initrds
out-of-band and copy them to /target with a script every time?"
adding modules to the fai-cd initrd
Is there a file somewhere that I can tell fai-cd to add dm_mod, dm_crypt, or any other kernel module to the fai-cd initrd?

Re: FAI not picking up hostname from DNS
Thanks Michael,
that worked,
i just thought it would've picked up hostname from DNS when getting the ip.
Redhat kickstart systems i setup didn't need the
option host-name "vm00"
so i didn't think this did.
thanks,
James
Michael Tautschnig wrote:
Hmm, Usually, you can boot very well even if the hostname is not set -

well the dns name has been set to that address in BIND
DHCP entry is like:
group {

next-server tftpserver;
filename "linux-install/pxelinux.0";
# You need an entry like this for every host
# unless you're using dynamic addresses
host vm00 {
hardware ethernet 00:0C:xx:xx:xx:xx;
fixed-address xxx.xxx.xxx.xxx;
}
}
Well, you don't set a name here, at least not one for the client to see; try
adding
host-name "vm00";
after your fixed-address line, that might help.

also i do an ifconfig and everything to doublecheck before reboot and

Re: FAI not picking up hostname from DNS
So, after the install, before faireboot, the hostname command get's you a "host"? Or is the hostname set corectly in the shell Usually I only see this, if my DHCP doesn't know the system and gives it a random ip from the pool. yeah, the shell shows [EMAIL PROTECTED] i can type hostname and it'll result in "host" On Etch? Yes I have no idea how i would set the hostname since i thought it would just know from DHCP + BIND Are you absolutely sure the host's mac and everything is correct in dhcp? Does it really get the intended IP or some random one? I wouldn't be able to pxeboot it if it weren't. also i do an ifconfig and everything to doublecheck before reboot and also all the system messages during install and everything seems to match up. TIA -James
Re: FAI not picking up hostname from DNS
What's the exact symptom? System won't pickup classes defined cause it can't define system hostname. I noticed it just default sets it to "host" and then choose the classes defined in the *) entry in the 50-host-classes file my hostname is vm00.blahblahblah.com here's my class entry: # use a list of classes for our demo machine case $HOSTNAME in vm*) echo "FAIBASE DHCPC SETUPSTORAGE" ;; *) echo "FAIBASE DHCPC SETUPSTORAGE" ;; esac (ifclass I386 || ifclass AMD64) && echo GRUB exit 0 the fai and distribution version yo are using? FAI 3.2.8 June 15 cd or pxe install? PXE It sometimes happend, and there was some confusion in hostname handling in FAI in some versions - but if you system is iself set to some random hostname (things I had at time is "host", "debian" or completly empty) \ I have no idea how i would set the hostname since i thought it would just know from DHCP + BIND Sure, you DNS and DHCP should be fully fcuntional, and you shuold be very sure that there is no secsond dhcp running... There's only one DHCP server running TIA -James
FAI not picking up hostname from DNS
Hey guys, i noticed that FAI isn't picking up my system's hostname from my DNS servers. it SHOULD be picking them up right? or do i have to explicity set the host address related to hostname in /srv/fai/nfsroot/live/filesystem.dir/etc/hosts? TIA -James

DHCP assigned an IP address, but no other support from the university data center was needed. I had a bootfloppy with similar three-line sets for all the hosts in the computer classroom, and chose an appropriate hostname at boot time. This worked. More than a year has passed, and new versions of almost everything came out, so things may have changed. Give it a try. Thanks for the tip with the manual ip= directive. That definately worked. I might just edit the make-fai-bootfloppy script to make it easier to edit -James

The assignment of your classes is done if you install a host which is correctly configured (ip/dns-wise) to have the hostname "test" - that's the name you have in your case statement... Henning ok so the name test would have to be in my dns record with an ip address already set to it right? So is there a way to set a hostname to a host without having refer to dns just for the sake of pulling the class definitions? For me setting up dns records ahead of time would be kind of cumbersome. I want to be able to setup a generic host with defined packages and then assign it a dns record later. but i already have a network dhcp setup which i also would rather not have to mess with since it would take longer for me to deploy a computer if i have to go gather mac addresses and insert records. Is there anyway for me to set the hostname manually on the bootfloppy so it knows to pull the certain class definitions without a dns record? Thanks Much -James

Henning Ok i think i'm starting to understand all this now. Last thing i need to figure out is this. So now i have the entire class called TEST i've created a line in config/class/50-host-classes like : case $HOSTNAME in test) echo "FAIBASE DHCPC TEST" ;; i created a disk profile at config/disk_config/TEST disk_config disk1 primary / 150-300 rw,errors=remount-ro ; -c -j ext3 logical swap 40-500 rw logical /var 90-1000 rw ; -m 5 -j xfs logical /tmp 50-1000 rw ; -m 0 -j xfs logical /usr 200-4000rw ; -j xfs logical /home 50- rw,nosuid; -m 1 -j xfs # logical /homepreserve9 rw,nosuid; -m 1 -j ext3 i created a config/package_config/TEST PACKAGES aptitude postfix that's about it because i just want to test it as simply as possible right now. So how do i get the bootfloppy to call the "TEST" class? do i just do a #> make-fai-bootfloppy -s TEST ip=::dhcp nfsroot=127.x.x.x:/srv/fai/nfsroot cause that's my understanding now. if not please let me know On a side not it's not the actual english in the documentation that's hard to understand. It's just how to narrow down some of the information and filter out what i didn't need. In a more complex setup i imagine i'll be using most to all of the info but right now things are pretty simple i just need a few custom packages here and there and how to instruct a boot floppy/cd to grab that class. Maybe a guide for the impatient on creating a class by example and cut out the big details. i personally would find that useful. :D Thanks -James
FAI Classes
Hi Everyone i've just started using FAI recently and am having a pretty hard time understanding the classes to create different computer profiles My Setup: First off I'm NOT using PXE BOOT with DNS and DHCP. I'm creating boot cds and just using those to do installations i'm having to set the ip=:dhcp and nfsroot= manually when creating the boot disks I do however already have an existing DHCP server and client machines should be able to grab on to them like that. So i want to be able to create a different classes for different machines say like 1. PROFILE1 - BAREBONES 2. PROFILE2 - LAMP 3. PROFILE3 - GUI I've tried reading the wiki and documentation but it sounds like german to me (i'm not german). i don't understand where in the /srv/fai/config folders that i need to define these classes i'm assuming it would be under /srv/fai/config/class Also which scripts attach to those classes. so if i create a file /srv/fai/config/class/PROFILE1 how do scripts or hooks under /srv/fai/config/scripts/ or /srv/fai/config/hooks relate back to that class? Also how do i define which /srv/fai/config/disk_config file is gonna be read? Also for instance when booting on floppy i don't exactly have a choice of which class to boot. I don't comprehend text as well as examples. So the more examples of actual config scenarios the better for me. Appreciate the help Thanks -James

FAI with LVM
Hi guys i am a newbie with FAI and was wondering if there's an easy setup example for disks to use LVM Is it built in to the disk_config setups or do i have to use a custom hook for it? And if i have to use a custom hook can someone give me any examples? Appreciate it. Thanks, James
