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.conf(5):
nvme_load="YES"
nvd_load="YES"
DESCRIPTION¶
The
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.
