💅 NVME-LOG-CHANGED-(1) — the nvme-log-changed-alloc-ns-list glow-up

okay bestie, welcome to the NVMe Manual ✨ this one's all about pulling the Changed Allocated Namespace List log page off your drive. it's a whole vibe, let's get into it 🎀

🌸 NAME 🌸

nvme-log-changed-alloc-ns-list — literally sends the NVMe Changed Allocated Namespace List log page request, and then hands you back the result and the log. two for one, we love that for us 🫶

✨ SYNOPSIS ✨

nvme [<global-options>] log changed-alloc-ns-list <device>
                        [--raw-binary | -b]

🦋 DESCRIPTION 🦋

So the way this works: it retrieves the Changed Allocated Namespace List log page from an NVMe device and gives you the returned structure. that's it, that's the whole errand 🧚

The <device> parameter is mandatory — no cap, you can't skip it — and it has to be an NVMe character device (ex: /dev/nvme0). like, actual device node energy only 💅

On success, the returned Changed Allocated Namespace List log structure may come back to you in one of several ways, depending on which option flags you picked:

  • the structure may get parsed by the program and printed in a readable format 🌈
  • or the raw buffer may be printed to stdout so another program can parse it 👑

pick your fighter, bestie.

🔥 OPTIONS 🔥

  • -b, --raw-binary — print the raw Changed Namespace List log buffer to stdout. raw, unfiltered, main character energy 💀

👑 GLOBAL OPTIONS 👑

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

  • --dry-run — print the command that would be executed, but do not actually execute it. window shopping, basically 🛍️
  • --no-ioctl-probing — disable probing for 64-bit IOCTL support.
  • --no-retries — disable retry logic on transient errors. one shot, no second chances 😭
  • -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 — don't get greedy 🙈
  • --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. any other versions get rejected, periodt 🚫
  • --quiet — suppress informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. it's giving "i'm not reading all that" 🤫
  • --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). infinite patience era ⏳
  • -v, --verbose — increase the level of detail in the output. may be specified multiple times to further increase verbosity. yes you can stack it, go off 📈
heads up babes: these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file — CLI stays winning 👑

🌟 EXAMPLES 🌟

  1. print the Changed Allocated Namespace List Log page in a human readable format:
# nvme log changed-alloc-ns-list /dev/nvme0
  1. print the raw Changed Allocated Namespace List log to a file:
# nvme log changed-alloc-ns-list /dev/nvme0 --raw-binary > log.raw
⚠️ fr fr, it is probably a bad idea to not redirect stdout when using this mode. like, please redirect it. i'm begging 🥺
