libnvme(2)

πŸ’– NAME πŸ’–

struct nvme_lbaf β€” the LBA Format Data Structure, aka the little glow-up breakdown of how your drive lays out logical blocks πŸ’…


✨ SYNOPSIS ✨

okay bestie, here's the whole vibe, literally just three fields:

struct nvme_lbaf {
    __le16 ms;
    __u8 ds;
    __u8 rp;
 };

That's it. Three members. Small struct, big main character energy πŸ‘‘


πŸŽ€ Members πŸŽ€

  • ms β€” the Metadata Size, bestie. It tells you the number of metadata bytes provided per LBA, and it's based on the LBA Data Size indicated. No cap, that's literally the whole thing 🫢
  • ds β€” the LBA Data Size, aka the LBA data size supported, and it's reported as a power of two. It's giving "2ⁿ, deal with it" πŸ’€
  • rp β€” Relative Performance, and for the full tea you gotta go see enum nvme_lbaf_rp. iykyk 🌸

and that's the whole page, angel πŸ’œ This was libnvme(2) β€” yes the manual name itself, iconic β€” from the libnvme API Manual, dated July 2026. Stay slaying with your LBA formats, fr fr βœ¨πŸ¦‹πŸ’–
