NAME

nvd - NVM Express disk driver

SYNOPSIS

To compile this driver into your kernel, place the following lines in your kernel configuration file:

device nvme device nvd

Or, to load the driver as a module at boot, place the following lines in loader.conf5:

nvme_load="YES"
nvd_load="YES"

DESCRIPTION

The 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 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.

SEE ALSO

GEOM(4), nvme(4), geom(8), nvmecontrol(8), disk(9)

HISTORY

The driver first appeared in Fx 9.2.
