NVME_SET_FEATURES_ERR_RECOVERY(2)

💖 nvme_set_features_err_recovery(2) 💖

okay bestie, gather round, because we're diving into the libnvme API manual and honestly? this one's a lil baddie. it's called nvme_set_features_err_recovery, and no, that's not a typo, that's just how long the name is. she's iconic, she's verbose, and she sets the error recovery feature on your NVMe device. periodt. 🎀

✨ NAME ✨

nvme_set_features_err_recovery — set error recovery feature 💅

---

🦋 SYNOPSIS 🦋

int nvme_set_features_err_recovery (int fd , __u32 nsid , __u16 tler ,
       bool dulbe , bool save , __u32 *result );

like… look at her. six whole params. main character energy fr fr. ✨

🌸 ARGUMENTS 🌸

here's the tea on every single one of these, no skips, no cap:

• fd — the file descriptor of your nvme device. it's giving "your ticket to the show" 🎟️ you gotta have it or nothing happens.
• nsid — Namespace ID. which namespace are we talking to? this one. 👑
• tler — Time-limited error recovery value. it's a __u16, it's mysterious, it's doing the most. 🕰️✨
• dulbe — Deallocated or Unwritten Logical Block Error Enable. yes the acronym is a mouthful, yes it's a bool, yes it's slaying. 🫶
• save — Save value across power states. basically "remember this even after a nap" 😴💾 set it true and she'll hold onto it through power states.
• result — The command completion result from CQE dword0. she's a __u32 * pointer, so she writes back to you. cute, communicative, obsessed. 📬

💀 RETURN 💀

so what do you get back? two options, bestie:

• The nvme command status if a response was received — see enum nvme_status_field for the whole rundown. iykyk.
• -1 with errno set otherwise. 😭 that's the "it didn't go how we wanted" path. not the vibe, but at least she tells you.

lowkey important: errno only gets set on that -1 route. don't go reading it when you got a real status back, that's not the move 🙈

and that's the whole page, bestie, we ate and left no crumbs 🍓🧚

sign-off time: this lil masterpiece came out of the libnvme world, and the docs are dated July 2026 — so like, technically from the future, and honestly? she's aging gorgeously. 💜 keep setting those features, stay hydrated, and don't forget your save flag if you want it to survive a power cycle. mwah 💅✨🌸
