nvd driver exposes NVM Express (NVMe)
namespaces as disks to the kernel disk storage API. It depends on the
nvme(4) driver for notification of existing NVMe
namespaces and submission of NVM I/O commands.
Device nodes from the
nvd driver will have
the format /dev/nvdX and are GEOM(4) disks which can be
partitioned by geom(8). Note that device nodes from the
nvme(4) driver are not GEOM(4) disks and
cannot be partitioned.
nvd driver defines a system-wide
maximum delete size for NVMe devices. The default is 1GB. To select a
different value, set the following tunable in
hw.nvd.delete_max=<delete size in bytes>
