Package: fai-setup-storage Version: 5.10.3 At https://github.com/faiproject/fai/blob/dc83bb502a9af5666fa4344ba8b710bbbd5c827d/lib/setup-storage/Exec.pm#L97 fai-setup-storage turns an "overlapping partitions" error into an "internal error".
The problem we ran into with this is that this also appears to happen if the disk used has pre-existing partitions that overlap. We were able to work around this by using dd if=/dev/zero bs=1024 count=64 of=<blockdevice> And rebooting, then re-running fai-setup-storage. Basically, we had two issues here: 1) The "internal error" obfuscated the fact that the pre-existing partition layout was broken. 2) Since our fai-setup-storage configuration throws away any existing partitions, it would be nice if fai-setup-storage would allow to clear such broken partitions automatically.
