🦋 enum nvme_smart_egcw — libnvme(9) API Manual 🦋

okay bestie, welcome to the cutest little corner of libnvme(9) 💖 this page is all about one enum and its warning-summary constants, and yes we're gonna cover every single one, no skips, no cap.

✨ NAME ✨

enum nvme_smart_egcw — Endurance Group Critical Warning Summary 🌸

like, it's literally the enum that gives you the critical warning summary for Endurance Groups, and it's giving "small but important" energy 👑

🦋 SYNOPSIS 🦋

enum nvme_smart_egcw {
    NVME_SMART_EGCW_SPARE ,
    NVME_SMART_EGCW_DEGRADED ,
    NVME_SMART_EGCW_RO

};

🎀 Constants 🎀

• NVME_SMART_EGCW_SPARE — if this one is set, then the available spare capacity of one or more Endurance Groups has fallen below the threshold 😭 that's the whole vibe: spare capacity said "we're low."
• NVME_SMART_EGCW_DEGRADED — if this is set, then the reliability of one or more Endurance Groups has been degraded due to significant media related errors or any internal error that degrades NVM subsystem reliability 💀 so yeah, reliability is not having a good time.
• NVME_SMART_EGCW_RO — if this is set, then the namespaces in one or more Endurance Groups have been placed in read only mode not as a result of a change in the write protection state of a namespace 🙈 read-only mode showed up, but not because the namespace's write protection state changed. periodt.

okay that's the whole page, bestie 🫶 — this was enum nvme_smart_egcw from libnvme(9), dated October 2026 💖✨
