-  Harvester sets the Longhorn disk driver to "auto" as described in [the Longhorn documentation](https://longhorn.io/docs/1.7.2/v2-data-engine/features/node-disk-support/). This means that NVMe disks will use the nvme bdev driver which provides the best performance. If testing with non-NVMe disks (e.g. SSDs), note that these will fall back to using the aio bdev driver, which requires that the disk size be an even multiple of 4096 bytes. Non-NVMe disks that do not meet this size constraint will not be added successfully.
