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
