NVME-DETACH-NS(1)

💅 NVME-DETACH-NS(1) — like, the deprecated one, bestie

okay so real talk, this is a page from the NVMe Manual, and it's the nvme-detach-ns girlie. she's giving legacy, she's giving "still here for the old scripts", and honestly? iconic of her to keep showing up. 🎀

✨ NAME ✨

nvme-detach-ns — sends the NVMe detach namespace command and returns the result. deprecated, bestie, we're literally telling you 😭

🦋 SYNOPSIS 🦋

nvme [<global-options>] detach-ns <device>
                        [--namespace-id=<nsid> | -n <nsid>]
                        [--controllers=<ctrl-list,> | -c <ctrl-list,>]

💖 DESCRIPTION 💖

So. This is a deprecated alias for nvme-ns-detach(1) — it's been kept around purely for scripts that were written against nvme-cli versions older than 3.0. The options and behavior are identical, no cap, the only thing that survived is the top-level command name itself. 🫶

New scripts should be using nvme ns detach instead, periodt. This alias prints a deprecation warning on stderr and may be removed in a future release, so like… don't get attached.

Heads up, bestie: nvme-ns-detach(1) has the full option reference. go read that one, it's the main character.

👑 GLOBAL OPTIONS 👑

These ones are defined up at the top-level nvme command, and they're all available to this subcommand too. slay.

• --dry-run — prints the command it would have executed, but doesn't actually execute it. it's giving window shopping. 🛍️
• --no-ioctl-probing — turns off probing for 64-bit IOCTL support.
• --no-retries — disables the retry logic on transient errors. one shot, no second chances 💀
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. only one output format at a time, don't be greedy.
• --output-format-version=<version> — picks the output format version. version 1 uses the original field naming, while version 2 (the default ✨) gives you more consistent and script-friendly field names. any other version? rejected. not on the list, not invited. 🙈
• --quiet — suppresses informational messages. errors still get reported (of course they do), and --quiet cancels any --verbose for the library log level.
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). the way that's just forever…
• -v, --verbose — increases the level of detail in the output. you can stack it multiple times to get even more verbose. go off, keep going, we love a yapper 💬

Oh and also — these options can be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file, always. the flag is the main character, the file is the supporting cast. 🎬
