Public bug reported:
MaaS and curtin currently doesn't support creating RAID arrays with NVMe
devices using the Intel Virtual RAID On CPU technology. Even worse, when
it encounters one, it tries to destroy it, but fail to do it also.
Creating a VROC array requires creating an external container via mdadm (-e
option, maybe this one could be generalized):
mdadm -C /dev/md/imsm0 /dev/nvme[0-3]n1 -n 4 -e imsm
Then the RAID array can be created:
mdadm -C /dev/md126 /dev/md/imsm0 -n 4 -l 5
