@DiegoP I believe mdadm will still be allowed to work, but I think you’re supossed to use “mdraid=true” for a kernel argument. If this is not set, FOG won’t know to build the array. This would help explain why the disk couldn’t find a partition layout as well since it’s expecting to be part of an array (which then looks/acts as the disk you’re truly working with.
As for “partclone to partimage” I’m not sure I understand.
Fog moved FROM partimage -> partclone way back in the 1.0.0 days as partimage has been obsolete for quite some time now.
