nvme-zns-set-zone-desc - Set extended descriptor data for a
zone
nvme [<global-options>] zns set-zone-desc <device>
[--namespace-id=<NUM> | -n <NUM>]
[--start-lba=<IONUM>, -s <IONUM>]
[--zrwaa | -r]
[--data=<FILE>, -d <FILE>]
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. The broadcast value
0xffffffff can also be given as all or -1.
-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)
The following options are defined at the top-level nvme command
and are available to this subcommand:
--dry-run
Print the command that would be executed, but do not
actually execute it.
--no-ioctl-probing
Disable probing for 64-bit IOCTL support.
--no-retries
Disable retry logic on transient errors.
-o <fmt>, --output-format=<fmt>
Set the reporting format to normal, tabular,
'json, or binary. Only one output format may be used at a
time.
--output-format-version=<version>
Select the output format version. Version 1 uses
the original field naming, while version 2 (default) provides more
consistent and script-friendly field names. Other versions are rejected.
--quiet
Suppress informational messages. Errors are still
reported, and --quiet cancels any --verbose for the library log level.
--set-options=<key=value>[,<key=value>...]
Set libnvme library options for this invocation.
Supported keys are force-4k, mi-probe-enabled,
test-base-dir and test-sysfs-dir.
--timeout=<ms>
Set the timeout for the command in milliseconds.
infinite or -1 waits without a time limit (0xffffffff).
-v, --verbose
Increase the level of detail in the output. May be
specified multiple times to further increase verbosity.
These options can also be set as machine-wide defaults in
nvme-cli.conf(5). A command-line flag always overrides the file.
•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
