I can confirm that disks with LVM can not be cleanly re-installed with FAI 4.0.6. A wipefs command fails, causing the whole setup-storage to fail.
We have only a couple of such systems, all with LVM on top of RAID1, and for these, I have a hook to task partition with the following content: vgremove -f lv1 mdadm --stop /dev/md0 mdadm --stop /dev/md1 dd if=/dev/zero of=/dev/sda bs=10240 count=100000 dd if=/dev/zero of=/dev/sdb bs=10240 count=100000 Perhaps not all of this is necessary (such as zeroing a whole gigabyte of disk), but this combination reliably wipes both the kernel data and actual disk sufficiently to enable a clean reinstall.
