Sourceslist on Multi Distro
Hi list. i have the Problem that Fai is using the Debian Squeeze Sources wen installing ubuntu. My setup is a Ubuntu LTS Server with a Debian Squeeze NFSRoot. Wen i install the default Debian it works fine, but wen i try to install ubunut fai is using the wrong sources. I can see that fai is using the right base.tgz for ubuntu but installing packedges from Debian. Which sources list do i need to alter, that he is using the right apt repository? Mark
Re: Sourceslist on Multi Distro
There is a Fai internal method that copies the sources.list fron nfsroot to the install system. In my example code for ubuntu / multi installs you find which step you have to disable with a hook in order to prevent that. Or check fai sources to find it (I dont know it anymore and cannot look it up myself now im on the road)...

Have a look at section 7.2 http://fai-project.org/fai-guide/ar01s07.html For each task you can define hooks. See also http://fai-project.org/fai-guide/ar01s07.html#_anchor_id_hooks_xreflabel_hooks_hooks -- regards Thomas

Hi, thanks, i missed the part with the default task.

Setup-storage failure for LVM on wheezy
Hello, Trying to install a wheezy host using FAI 4.0~beta3+experimental7, I have some troubles with setup-storage; the current disk partitioning is the following: sda1 = primary partition for /boot sda2 = primary partition for lvm volumes = vg0/root, vg0/usr, ... The new partitioning should be the same, without preserving anything because of alignment issues. This is what happens: [...] Executing: wipefs -a /dev/sda1 Executing: vgchange -a n vg0 Executing: wipefs -a vg0/var Command had non-zero exit code There seems to be 2 problems: - wipefs argument should be /dev/vg0/var - vgchange -a n should not be called before wipefs, as it prevents it from seeing the partition I have tweaked Commands.pm so that it does not fail in this case, but a clean fix might be useful in a future version of setup-storage. -- Nicolas

Hello Toomas, many thanks for your explanations and the script so far! On Mon, Jan 16, 2012 at 11:30:22AM +0200, Toomas Tamm wrote: > We have used diskless clients for years.

This is where I am working right now. I did not find a clear documentation on how to do the implementation (chroot and booting) best, by more or less try and error I ended up with something that magically works and already looks quite promising, however I would like to understand a bit more. Perhaps you or someone having deeper insights into the subject can give some comments, tips and tricks on what I did so far: I install the chroot with: export LC_ALL=C; fai -vNu diskless dirinstall /opt/live/filesystem.dir/ The FAI classes used are almost identical to a comparable disk installation; only /etc/hosts and /etc/resolv.conf need to be modified from what FAI produces. The directory /opt is exported via NFS (I can't use NFSv4, right?). Now I create the PXE configuration: ... kernel vmlinuz-2.6.32-5-486 append initrd=initrd.img-2.6.32-5-486 ip=dhcp root=/dev/nfs nfsroot=/opt boot=live I was not able to figure out what boot=live exactly means. What is the difference to boot=nfs? Are there other alternatives? When booting the client, it seems to pick up the hostname from dhcp/dns if it has been added to these services. This is already great. If the machine is unknown to dhcp/dns it picks up 'host'. Can I easily modify or influence this behavior? What's the recommended implementation? Problems I encountered before on debian-edu are security aspects: We would like to use Kerberos and NFSv4 for mounting the home directories. Of course a keytab in a readable chroot shared by many machines is not what you want. Any ideas how to handle that best? I documented what I got so far in more detail here: http://wiki.debian.org/DebianLAN/Setup_A> Hints, tips and tricks as well as pointers are appreciated. Thanks! Best regards, Andi

NFS v4 for the root file system is not supported by initramfs and live-boot. But if you need FNS v4 only for /opt, just mount it later. > I was not able to figure out what boot=live exactly means. What is This is described in live-boot(7). > great. If the machine is unknown to dhcp/dns it picks up 'host'. > Can I easily modify or influence this behavior? What's the > recommended implementation? I recommend using DHCP. But I guess live-boot has more options to define the host name. > Problems I encountered before on debian-edu are security aspects: We > would like to use Kerberos and NFSv4 for mounting the home > directories. That should be possible. P.S.: NFS v4 for the root file system is possible using dracut instead of initramfs-tools and live-boot. I did this a few days ago, but it's not yet documented. -- regards Thomas
