🎀 Constants 🎀

okay so these are the three little flag vibes, and each one is a warning that's been set. Let's go one by one, no skipping 💅

• 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. like, the spare tank is looking thin, bestie 😭
• NVME_SMART_EGCW_DEGRADED — if this is set, then the reliability of one or more Endurance Groups has been degraded. and why? because of significant media related errors, or any internal error that degrades NVM subsystem reliability. it's giving "the vibes are off and it's hardware's fault" 💀
• NVME_SMART_EGCW_RO — if this is set, then the namespaces in one or more Endurance Groups have been placed in read only mode. and hear me out — this is not because of a change in the write protection state of a namespace. so don't go blaming write protection, that's a different situation entirely 🫶

---

fr fr, every single one of these is conditional — "if set" — so check whether the bit is actually on before you spiral 🙈
