NVME-ZNS-SET-ZONE(1) NVMe Manual NVME-ZNS-SET-ZONE(1)

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

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>]

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.

-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.

•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
