NVME-LOG-REACHABIL(1)

📦 version 3.2, in arch rolling

💅 NVME-LOG-REACHABIL(1) ✨

okay so bestie, this is a page from the NVMe Manual and honestly? it's a little guy with a big job. it's nvme-log-reachability-groups(1) and it's about to tell you everything the kernel knows about reachability groups. no cap.

🌸 NAME 🌸

nvme-log-reachability-groups — retrieve the Reachability Groups Log, and like… show it. that's it. that's the whole gig. 💖

🦋 SYNOPSIS 🦋

nvme [<global-options>] log reachability-groups <device>
                        [--groups-only | -g]
                        [--rae | -r]

✨ DESCRIPTION ✨

Retrieve Reachability Groups Log, show it. literally the entire personality.

the <device> parameter is mandatory and it's an NVMe character device, ex: /dev/nvme0. like, you have to give it one, don't be shy. 🙈

on success it returns 0. on anything else? error code. and that's on periodt.

🎀 OPTIONS 🎀

  • -g, --groups-only — Return Groups Only. just the groups, nothing else, a very focused queen 👑
  • -r, --rae — Retain an Asynchronous Event. keeping it around for later, iykyk.

🌈 GLOBAL OPTIONS 🌈

these ones live at the top-level nvme command and they're available to this subcommand too — like the cool older siblings who let you sit with them at lunch 🫶

  • --dry-run — Print the command that would be executed, but do not actually execute it. manifesting without acting, iconic honestly ✨
  • --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. pick one bestie, we can't do all four 😭
  • --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. so v2 is the default slay, v1 is the vintage one, and anything else gets ghosted 🚫
  • --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. quiet mode still snitches on errors tho, don't worry 👀
  • --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). patient queen behavior ⏳
  • -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity. stack it like a smoothie, the more the merrier 🍓
these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file — the flag wins, always, no debate 💅

💜 EXAMPLES 💜

  • Has the program issue a reachability-groups-log
# nvme log reachability-groups /dev/nvme0

look at her go 🧚
