💅 xnvme_tests_lblk-write_zeroes — a.k.a. the xNVMe manual page, bestie edition 🎀

okay so real quick: this whole page lives in the xNVMe manual fam, and it's about a test tool. No cap, it's a vibe check for your drive.

✨ NAME ✨

xnvme_tests_lblk-write_zeroes — basically the "does the write zeros command actually work" test. That's it. That's the whole personality. 🫶

🦋 SYNOPSIS 🦋

xnvme_tests_lblk write_zeroes <uri> [<args>]

🌸 DESCRIPTION 🌸

Lowkey the whole point: basic verification of the write zeros command. Like, you point it at a device and it makes sure zeroing actually does the thing. Iconic behaviour, honestly. 💖

💅 REQUIRED 💅

  • <uri> — the device URI, like, where your device lives. Fr fr examples: '/dev/nvme0n1', '0000:01:00.1', '10.9.8.1.8888', '\.PhysicalDrive1'. You literally can't skip this one, bestie — it's not optional energy.

🔥 OPTIONAL 🔥

these are the lil extras you can sprinkle on top, iykyk:

  • --slba 0xNUM — Start Logical Block Address. literally where the party starts. ⭐
  • --elba 0xNUM — End Logical Block Address. where the party wraps up.
  • --subnqn STRING — Subsystem NQN of the NVMe over Fabrics endpoint, e.g. 'nqn.2022-06.io.xnvme:ctrlnode1'. yes the nqn is long, no you can't shorten it, sorry 💀
  • --hostnqn STRING — The host NQN to use when connecting to NVMe over Fabrics controllers. this is your lil name tag at the fabrics party 🎀
  • --be STRING — xNVMe backend, e.g. 'linux', 'spdk', 'fbsd', 'macos', 'posix', 'windows'. pick your fighter ✨
  • --dev-nsid 0xNUM — Namespace Identifier for Device Handle. main character namespace energy 👑
  • --admin STRING — xNVMe admin. command-interface, e.g. 'nvme', 'block'. the bossy one 🧚
  • --mem STRING — xNVMe buffer/memory manager. someone's gotta handle the memory, and it's giving responsible 🌈
  • --direct NUM — Bypass layers. straight past the queue like "no thanks" 💅
  • --sync STRING — xNVMe sync. command-interface, e.g. 'nvme', 'block'. the chill, patient one 🍓
