🦋 nvme-ns-rescan(1) — the NVMe manual, but make it cute 🦋

okay so bestie, welcome to nvme-ns-rescan 💅 this is a page from the NVMe Manual, and it's literally the entire vibe of "hey controller, go look at your namespaces again." Let's get into it ✨

🌸 NAME 🌸

nvme-ns-rescan — aka the little command that rescans the nvme namespaces 🫶

🎀 SYNOPSIS 🎀

nvme [<global-options>] ns-rescan <device>

that's the whole shape of it, no cap 💖

✨ DESCRIPTION ✨

So what does it do? It requests the NVMe controller rescans the namespaces. That's it. That's the errand 🧚

Now listen, the <device> param is mandatory — like, not optional, not "ehh maybe later," mandatory 🙈 and it must be an NVMe character device, for example /dev/nvme0. Get that wrong and it's not giving what you need it to give 💀

🔥 OPTIONS 🔥

👑 GLOBAL OPTIONS 👑

okay so these bad boys are defined at the top-level nvme command, and they're available to this subcommand too. main character energy, they show up everywhere 🌈

  • --dry-run — prints the command that would be executed, but does not actually execute it. window shopping, but for syscalls 💅
  • --no-ioctl-probing — disables probing for 64-bit IOCTL support. if you wanna skip the vibe check, here's your flag 😌
  • --no-retries — disables retry logic on transient errors. one shot, no takebacks 🎯
  • -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. and! only one output format at a time, so don't be greedy bestie ✨
  • --output-format-version=<version> — selects 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 — no exceptions 🚫
  • --quiet — suppresses informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. shhh 🤫
  • --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. mix and match, it's giving customization 💜
  • --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). patience is a virtue fr fr ⏳
  • -v, --verbose — increases the level of detail in the output. may be specified multiple times to further increase verbosity — stack it, girl 📚
also! these options can be set as machine-wide defaults in nvme-cli.conf(5) 🎀 but a command-line flag always overrides the file. command line stays undefeated 👑

💖 EXAMPLES 💖

  • rescans the nvme namespaces. literally what it says on the tin 🍓
# nvme ns-rescan /dev/nvme0
