Send NVMe Namespace management command to create namespace, returns results.


nvme create-ns <device> [--nsze=<nsze> | -s <nsze>]
                        [--ncap=<ncap> | -c <ncap>]
                        [--flbas=<flbas> | -f <flbas>]
                        [--dps=<dps> | -d <dps>]
                        [--nmic=<nmic> | -m <nmic>]
                        [--anagrp-id=<anagrpid> | -a <anagrpid>]
                        [--nvmset-id=<nvmsetid> | -i <nvmsetid>]
                        [--block-size=<block-size> | -b <block-size>]
                        [--timeout=<timeout> | -t <timeout>]
For the NVMe device given, sends a namespace management command to create
the namespace with the requested settings. On success, the namespace
identifier assigned by the controller is returned.

The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

-s,  --nsze

The namespace size.

-c,  --ncap

The namespace capacity.

-f,  --flbas

The namespace formatted logical block size setting. Conflicts with --block-size argument.

-d,  --dps

The data protection settings.

-m,  --nmic

Namespace multipath and sharing capabilities.

-a,  --anagrp-id

ANA Gorup Identifier. If this value is 0h specifies that the controller determines the value to use

-i <nvmsetid>, --nvmset-id=<nvmsetid>

This field specifies the identifier of the NVM Set.

-b,  --block-size

Target block size the new namespace should be formatted as. Potential FLBAS values will be values will be scanned and the lowest numbered will be selected for the create-ns operation. Conflicts with --flbas argument.
