## NAME

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

## SYNOPSIS

    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
