** `sizeGibibytes`: The size of the logical drive as an integer to create in GiB. If unspecified or set to `0`, it will use the maximum capacity of physical drive for the logical drive.
* `softwareRAIDVolumes`: {product-title} {product-version} does not support software RAID. The following information is for reference only. This configuration contains the list of logical disks for software RAID. If you do not specify `rootDeviceHints`, the first volume is the root volume. If you set `HardwareRAIDVolumes`, this item will be invalid. Software RAIDs will always be deleted. The number of created software RAID devices must be `1` or `2`. If there is only one software RAID device, it must be `RAID-1`. If there are two RAID devices, the first device must be `RAID-1`, while the RAID level for the second device can be `0`, `1`, or `1+0`. The first RAID device will be the deployment device. Therefore, enforcing `RAID-1` reduces the risk of a non-booting node in case of a device failure.
