LinuxQuestions.org - Problems configuring FAI for installation on clients

Hi

I'm trying to use FAI (http://fai-project.org) to install a new Ubuntu System to my computer. I just had two days of headache and bug fixes with the configuration files, so maybe there is someone who could help:

The task partition reads a particular disk_config file from the config archive given over FAI_CONFIG_SRC boot option from my local installation server. I'm currently using localhost for testing purposes.

The partition scheme consists of a logical volume layer to create one logical volume out of all clients' disks.
On that there should be a layer of LUKS (cryptsetup) for a full disk encryption with AES.
On the third layer (encrypted) should be another LVM system defining the usable partitions like /, /home, /var etc.

I installed some clients with exactly this layout and the inner Debian / Ubuntu systems work great (the installation process is a lot better with Debian in this case).

After having fixed a thousand of this nasty bugs with the configuration file, I get struggled.

Error message by LVM:

Code:

Cannot determine size of /dev/crypt_format_system-volume - scheme unknown

Current config file for a client with three disks:

Code:

disk_config disk1 disklabel:msdos fstabkey:uuid align-at:512B bootable:1

primary  /boot/efi  512M  vfat  ro

primary  /boot      2G    ext2  ro

Thanks in advance for reading this long post :)
