gnt-storage(8)

💖 gnt-storage(8) — Ganeti storage administration 💖

okay bestie, welcome to gnt-storage, the storage-handling command of the Ganeti cluster toolkit. this page is from version 3.1.0~rc2, so like, keep that in mind. let's get into it 🫶

---

✨ NAME ✨

gnt-storage — Ganeti storage administration. that's it, that's the name, iconic 💅

---

✨ SYNOPSIS ✨

gnt-storage {command} [arguments...]

---

🌸 DESCRIPTION 🌸

so gnt-storage is your girl for managing all the storage that lives inside the Ganeti cluster. at the moment, she only manages external storage (ExtStorage). that's the whole vibe for now — internal storage management is out here waiting for its glow-up (more on that in NOTES 👀).

---

🎀 COMMANDS 🎀

🔍 DIAGNOSE

diagnose

this one is the detective of the group, fr fr 🔎 she hands you detailed info about the state of every single ExtStorage provider available in the Ganeti cluster.

here's the tea though: the state of each provider is calculated per nodegroup 🫢 which means a provider can be valid (aka usable) for some nodegroups and invalid (aka not usable) for others. so if you're sitting there like "why is my installed ExtStorage provider not working for this one nodegroup??" — this command is literally going to show you why. maybe it's missing from a node, maybe it's only partially installed. 🤷♀️

she shows you the details of all ExtStorage providers and the reasons they are (or aren't) valid for every nodegroup in the cluster. no cap. 💅

---

💌 INFO

info
[provider]

this one lists detailed information about each ExtStorage provider found in the cluster, including:

• its nodegroup validity
• the supported parameters (if any) and their documentations
• etc. ✨

quick heads up though: for each ExtStorage provider, only the valid nodegroups will be listed. the invalid ones? not invited to this party 💀

run it with no arguments and it'll display info for all ExtStorage providers found in the cluster. give it ExtStorage provider's names as arguments and it will list info only for the providers you named. slay. 👑

---

📝 NOTES 📝

manifesting time bestie 🌈 — in the future, gnt-storage can be extended to also handle internal storage (like lvm, drbd, etc.) and also provide diagnostics for them too. periodt.

it can also be extended to handle internal and external storage pools, if/when this kind of abstraction is implemented inside Ganeti. so like… watch this space 👀✨
