NVME-SNDK-NAMESPAC(1)

💖 NAME 💖

okay so bestie, this is the NVME-SNDK-NAMESPAC(1) page — title and all — and it lives in the NVMe Manual. The command is nvme-sndk-namespace-resize, and its whole main-character job is: resizes the device's namespace. periodt. 💅

---

✨ SYNOPSIS ✨

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

🦋 DESCRIPTION 🦋

okay so for the NVMe device you hand over, this sends the sndk Vendor Specific Command that modifies the namespace size reported the device. iykyk 💫

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

🚨 no cap: this will only work on Sandisk devices supporting this feature. Results for any other device are undefined. fr fr 💀

🎀 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. bestie, read the valid values carefully 👑

🌈 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. very "look but don't touch" energy ✨
• --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. the way that's so tidy 🧚

🔥 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
