NAME
----
nvme-zns-set-zone-desc - Set extended descriptor data for a zone

SYNOPSIS
--------
[verse]
'nvme zns set-zone-desc' <device> [--namespace-id=<NUM> | -n <NUM>]
			[--start-lba=<IONUM>, -s <IONUM>]
			[--zrwaa | -r]
			[--data=<FILE>, -d <FILE>]
			[--timeout=<timeout> | -t <timeout>]

DESCRIPTION
-----------
For the NVMe device given, issues the Zone Management Send command with the
Set Zone Descriptor Extensions action. The input will default to stdin.
Alternatively, the data may come from a file that can be specified. The data
length will automatically be calculated from the zns identify namespace.

OPTIONS
-------
-n <NUM>::
--namespace-id=<NUM>::
	Use the provided namespace id for the command. If not provided, the
	namespace id of the block device will be used. If the command is issued
	to a non-block device, the parameter is required.

-s <lba>::
--start-lba=<lba>::
	The starting LBA of the zone to manage send.

-r::
--zrwaa::
	Allocate Zone Random Write Area to zone.

-d <FILE>::
--data=<FILE>::
	Optional file for data (default stdin)

-t <timeout>::
--timeout=<timeout>::
	Override default timeout value. In milliseconds.

EXAMPLES
--------
* Write "hello world" into the zone descriptor for namespace 1's first zone
  (requires device supports a large enough zone extended data) 
+
------------
# echo "hello world" | nvme zns set-zone-desc /dev/nvme0 -n 1 -s 0
