* The number of created Software RAID devices must be 1 or 2. If there is only
one Software RAID device, it has to be a RAID-1. If there are two, the first
one has to be a RAID-1, while the RAID level for the second one can
0, 1, or 1+0. As the first RAID device will be the deployment device,
one has to be a RAID-1, while the RAID level for the second one can be
0, 1, 1+0, 5, or 6. As the first RAID device will be the deployment device,
enforcing a RAID-1 reduces the risk of ending up with a non-booting node
in case of a disk failure.
