SYNOPSIS

nvme [<global-options>] zns zrwa-flush-zone <device>
                        [--namespace-id=<NUM> | -n <NUM>]
                        [--lba=<LBA> | -l <LBA>]

DESCRIPTION

For the NVMe device given, issues the Zone Management Send command with the "flush Zone" action. This will flush the zone that is opened as zone random write area.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

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. The broadcast value 0xffffffff can also be given as all or -1.

-l <lba>
--lba=<lba>

The LBA to flush up to.

GLOBAL OPTIONS

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.

EXAMPLES

  • flush the first zrwa of first zone for zrwacg(15) on namespace 1: 

    # nvme zns zrwa-flush-zone /dev/nvme0 -n 1 -l 15
