# nvme-sndk-namespace-resize(1)

Resizes the device's namespace.

## NAME

nvme-sndk-namespace-resize - Resizes the device's namespace.

## SYNOPSIS

```
nvme [<global-options>] sndk namespace-resize <device>
                        [--nsid=<NAMESPACE ID>, -n <NAMSPACE ID>]
                        [--op-option=<OP OPTION>, -O <OP OPTION>]
```

## DESCRIPTION

For the NVMe device given, sends the sndk Vendor Specific Command that modifies the namespace size reported the device.

The \<device\> parameter is mandatory NVMe character device (ex: /dev/nvme0).

This will only work on Sandisk devices supporting this feature. Results for any other device are undefined.

## OPTIONS

\-n \<NAMESPACE ID\>, --namespace-id=\<NAMESPACE\_ID\>

Namespace ID; ID of the namespace to resize The broadcast value 0xffffffff can also be given as *all* or *-1*.

\-O \<OP OPTION\>, --op-option=\<OP OPTION\>

Overprovisioning Option; defaults to 0xF Valid Values: 0x1 - 7% of Original TNVMCAP reported value 0x2 - 28% of Original TNVMCAP reported value 0x3 - 50% of Original TNVMCAP reported value 0xF - 0% of Original TNVMCAP reported value (original config) All other values - reserved

## 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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## EXAMPLES

• Resizes namespace 1 to 50% of the original TNVMCAP reported value:

```
# nvme sndk namespace-resize /dev/nvme0 -n 1 -O 3
```

• Resizes namespace 2 to 7% of the original TNVMCAP reported value:

```
# nvme sndk namespace-resize /dev/nvme0 --namespace-id=2 --op-option=1
```

## NVME
