Martin,
On commissioning, MAAS won't detect your partitions on the secondary
disk and for the moment, MAAS won't gain that ability to auto-detect
partitions.
On deployment, these partitions will be wiped out as a premise that MAAS
won't keep old data. This is a security mechanism/feature to
Thank you for the clarification.
Yes, it is pre-partioned.
The bigger problem with this is, that even the disk is not used, all the
partitions get *deleted*.

The commissioning process does not detect the partitions of the disk
because MAAS will change the layout after commissioning. If the disk
layout has been changed from MAAS itself, and the user re-commissions
the machine, the user has the opportunity to "keep" the storage changes,
if so desires.
