The zone append command writes the logical blocks specified by the command to the medium from the data data buffer provided. Will use stdin by default if you don’t provide a file.

On success, the program will report the LBA that was assigned to the data for the append operation.

-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 <IONUM>, --zslba=<IONUM>, -z <IONUM>, --data-size=<IONUM>

Size of data, in bytes.

-y <IONUM>, --metadata-size=<IONUM>

Size of metadata in bytes.

-d <FILE>, --data=<FILE>

Data file providing the data to write. If none provided, contents are sent from STDIN.

-M <FILE>, --metadata=<FILE>

Metadata file, if necessary.

-l, --limited-retry

Sets the limited retry flag.

-f, --force-unit-access

Set the force-unit access flag.

-r <NUM>, --ref-tag=<NUM>

Optional reftag when used with protection information.

-m <NUM>, --app-tag-mask=<NUM>

Optional application tag mask when used with protection information.

-a <NUM>, --app-tag=<NUM>

Optional application tag when used with protection information.

-p <NUM>, --prinfo=<NUM>

Protection Information field definition.

•Append the data "hello world" into 4k worth of blocks into the zone starting at block 0 for namespace 1: 

# echo "hello world" | nvme zns zone-append /dev/nvme0 -n 1 -s 0 -z 4k
