FAI for Ubuntu/karmic
Hi Developers, after a successful workshop with Thomas, I would like to sent some hints and patches for getting FAI working on Ubuntu/karmic to install Ubuntu/karmic. I've checkout the latest subversion of fai: svn co svn://svn.debian.org/svn/fai/trunk fai-sources After applying the attached patches (fai-ubuntu-control.patch, fai-ubuntu-upstart.patch) you can successfully build and install the fai packages: $ cd fai-sources $ dpkg-buildpackage $ cd .. $ sudo dpkg -i fai-quickstart_3.3_all.deb fai-doc_3.3_all.deb fai-server_3.3_all.deb In Ubuntu there is no package with the name syslinux-common, the package name here is syslinux. Ubuntu switched to upstart as init replacement, so we need to start the main fai script via upstart. In the patch I check the environment variable UPSTART_JOB, if fai is called via upstart init application. After that you can create a new /etc/fai-karmic directory and modify the configuration to match Ubuntu package names. See fai-ubuntu-NFSROOT.patch as example. Here we have used unionfs-fuse instead of aufs2. Ubuntu removed the aufs2 binary packages in Karmic. After that I've setup a local repository with the fai packages for the installation and client system: # mkdir -p /srv/www/fai/ # cp fai-client_3.3_all.deb fai-nfsroot_3.3_all.deb /srv/www/fai/ # cd /srv/www/fai # dpkg-scanpackages . /dev/null |gzip -v9 Packages.gz My apache DocumentRoot is /srv/www. My /etc/fai/apt/sources.list contains following line for the local repository: deb http://10.1.1.1/fai/ ./ The next step is to call fai-setup: # fai-setup -C /etc/fai-karmic -v If this successfully creates a nfsroot, you need to manually configure upstart: (should I create a patch for make-fai-nfsroot?) # chroot /srv/fai/nfsroot-karmic/live/filesystem.dir # mkdir /etc/unused # mv /etc/init/* /etc/unused/ # cp /etc/unused/mountall* /etc/init # cp /etc/unused/*udev* /etc/init # cp /etc/unused/hostname.conf /etc/init # exit # cp $HOME/fai-sources/upstart/fai.conf /srv/fai/nfsroot-karmic/live/filesystem.dir/etc/init After that you could use the patch fai-ubuntu-configspace.patch to create a Ubuntu/karmic compatible configuration including grub2 installation. Then you can use fai-chboot: # fai-chboot -F -I -v -C /etc/fai-karmic/ faiclient After booting Ubuntu we found a small bug in the fstab generation. The swap entry shouldn't be checked via fsck, this line: /dev/sda5 noneswaprw 0 2 Should be generated like this: /dev/sda5 noneswaprw 0 0 Attached is a fai.log from the installation. There might be a change needed in setup-storage, a variable is not initialized. One open bug is that the keymap while the installation is running is not set correctly, see: Executing GERMAN.var ++ KEYMAP=de-latin1-nodeadkeys Loading keymap(s) de-latin1-nodeadkeys .../usr/bin/ckbcomp: Can not find file symbols/de-latin1-nodeadkeys in any known directory It would be nice if you could integrate some of the patches. If you think they are to ugly, you could at least add them to the enterprise edition ;) best regards Waldemar fai.log.gz Description: application/gunzip --- /etc/fai/NFSROOT2009-11-11 15:37:18.0 +0100 +++ /etc/fai-karmic/NFSROOT 2009-11-11 15:37:46.206251851 +0100 @@ -2,11 +2,10 @@ PACKAGES aptitude nfs-common fai-nfsroot module-init-tools ssh rdate lshw portmap -rsync lftp less dump reiserfsprogs e2fsprogs usbutils -hwinfo psmisc pciutils hdparm smartmontools parted mdadm lvm2 +rsync lftp less reiserfsprogs e2fsprogs usbutils +psmisc pciutils hdparm smartmontools parted mdadm lvm2 dnsutils ntpdate dosfstools jove xfsprogs xfsdump -procinfo dialog discover -console-tools console-common +procinfo dialog discover dump console-setup iproute udev subversion liblinux-lvm-perl # needed for the simple examples @@ -17,11 +16,11 @@ PACKAGES aptitude I386 grub lilo read-edid -linux-image-486 aufs-modules-2.6-486 +linux-image unionfs-fuse PACKAGES aptitude AMD64 grub lilo -linux-image-2.6-amd64 aufs-modules-2.6-amd64 +linux-image unionfs-fuse PACKAGES aptitude IA64 elilo gnu-efi efibootmgr @@ -33,5 +32,5 @@ aboot PACKAGES aptitude POWERPC -linux-image-2.6-powerpc aufs-modules-2.6-powerpc +linux-image unionfs-fuse yaboot diff -Nur /usr/share/doc/fai-doc/examples/simple/class/50-host-classes /srv/fai/config-karmic/class/50-host-classes --- /usr/share/doc/fai-doc/examples/simple/class/50-host-classes 2009-11-10 18:24:28.0 +0100 +++ /srv/fai/config-karmic/class/50-host-classes2009-11-11 11:42:54.878174377 +0100 @@ -16,9 +16,11 @@ echo FAIBASE DHCPC LVM_XEN_SERVER XEN ;; puma) echo FAIBASE DHCPC RAID_XEN_VIRTUAL ;; +faiclient) + echo FAIBASE DHCPC GERMAN ;; *) echo FAIBASE DHCPC ;; esac -(ifclass I386 || ifclass AMD64) echo GRUB +(ifclass I386 || ifclass AMD64) echo GRUB_PC exit 0 diff -Nur /usr/share/doc/fai-doc/examples/simple/package_config/DEFAULT

Re: recent lvm.conf change in ubuntu/lucid breaks FAI setup-storage
Hi Michael, Michael Tautschnig wrote, Hi FAI Developers, recently Ubuntu changed the default lvm.conf file, they now use following: - # Since version 2.02.54, the tools distinguish between powers of # 1024 bytes (e.g. KiB, MiB, GiB) and powers of 1000 bytes (e.g. # KB, MB, GB). # If you have scripts that depend on the old behaviour, set this to 0 # temporarily until you update them. si_unit_consistency = 1 - This breaks setup-storage. Attached patch fixed it for me. But I think it will be semantical incorrect if someone uses new lvm-tools with si_unit_consistency equal 0. Any idea for a better fix? [...] This has already been fixed in the experimental builds, see also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=568794 The patch does more or less what you proposed to change; I just tried to make it slightly easier later on to also distinguish GiB/GB once also parted and all the other tools go for correct units handling. Where can I find the sources to the experimental binary debs? I haven't seen any branch in the subversion repository nor a deb-src line works for me. I just want to do some changes on top of the experimental stuff. (squashfs images as config space) bye Waldemar
swap fsck bug
Hi FAI developers,
it seems that fstab generation still contains the bug, that
swap will be checked. Attached patch fixes it for me.

Re: recent lvm.conf change in ubuntu/lucid breaks FAI setup-storage
Hi Michael, Michael Tautschnig wrote, I'd really appreciate if people started to contribute to those experimental builds!!! Don't hesitate to post any further questions! I started to get my work into the experimental build, but I have some problems with a simple setup. I checked out the lastest version of fai-source and fai-experimental onto a Debian/Lenny system. Then I have done following: cd /root/fai-sources export QUILT_PATCHES=/root/fai-experimental/patches/ export QUILT_PC=$(pwd)/debian/.pc quilt push -a debuild I installed the resulting fai packages and created a repository with the fai packages. These are added to /etc/fai/apt/sources.list. After that I created as usual the NFS root via make-fai-nfsroot. I copied over the default config space from /usr/share/doc/fai-docs/examples/simple to /srv/fai/config When I try to install a KVM client via: qemu-img create -f qcow2 /iso/bar.img 10G virt-install --vnc --noautoconsole --bridge br0 --hvm --accelerate --pxe -n foo -r 512 -f /iso/bar.img -m 54:52:00:00:00:02 I get following error message from setup-storage: Partitioning local harddisks using setup-storage Starting setup-storage 1.2+exp Can't use string () as an ARRAY ref while strict refs in use at /usr/share/fai/setup-storage//Volumes.pm line 83, $config_file line 1.

config space leftovers, when using own FAI_ACTION
Hi,
when using some home made FAI actions implemented as hooks, the
config space is not automatically unmounted, when NFS is used.
What about something like the attached patch, to fix this
situations?

problem with kernel cmdline
Hi,
when using following kernel command line to finetune some
NFS options:
append initrd=initrd.img-2.6.32-21-generic ip=dhcp NFSOPTS=-o
nolock,ro,wsize=2048,rsize=2048 root=/dev/nfs
nfsroot=/srv/fai/nfsroot boot=live FAI_FLAGS=verbose,sshd,createvt
FAI_ACTION=install
The function eval_cmdline will fail. Attached patch from
Thorsten Glaser t...@debian.org fixed it for me.
May be something for 3.4?
bye
