Hello, I'm trying to get FAI working for an install of several labs using Debian Wheezy. I'm using the latest wheezy install of FAI (which is version 4.0.6).
My install process has worked fine when I empty out the disk (dd if=/dev/zero of=/dev/sda bs=1024 count=512 is my friend) of the client machine. However, when I try to reinstall on top of a previous system which used LVM, I continually have failures. This led me to a few questions specifically about setup-storage: 1. Is there any documentation on all the names for the pre and post dependencies for a command? I'm having a very hard time deciding if there's a bug, or if my config has problems because it's hard for me to decode these strings. Specifically, what is self_cleared_* and why does it sometimes have a dev node suffix, and other times have a logical volume name? 2. Has anybody had luck with installing where an lvm setup previously existed? I see that the wipefs command always depends on a vgchange -a n command, and I don't understand how that could work, as the vgchange removes the device node. With no device node, there's no device to wipe. (Also, I see that for lvm, wipefs refers to a path like vg/fscache instead of /dev/vg/fscache. I'm not sure how that would ever work, either.) One of the few things that I can think of is that the kernel causes different behavior as to the dev nodes appearance/disappearance. I am using a stock debian kernel instead of the grml one because the grml one was crashing randomly on my test machine (which is similar to my lab machines). I appreciate any relevant feedback. -Ken Hahn
