LCTL-NODEMAP_INFO(8)

✨ LCTL-NODEMAP_INFO(8) ✨

okay bestie, so this is a page from the Lustre Configuration Utilities manual — it's the lctl-nodemap_info one 💖

---

🌸 NAME 🌸

lctl-nodemap_info — the little command that spills the tea about your nodemaps 💅

---

🦋 SYNOPSIS 🦋

lctl nodemap_info or
lctl nodemap info --name NODEMAP_NAME --property PROPERTY_NAME --list

---

💜 DESCRIPTION 💜

So like, nodemap_info is the one that hands you the receipts on all your defined nodemaps ✨ That means: are your nodemaps even active or nah, a whole list of every nodemap that's defined, and the actual values of specific nodemap parameters.

And here's the cute part — if you don't pass any options at all, it just gives you everything: every nodemap and every property it's got 👑

---

🎀 OPTIONS 🎀

• --name NODEMAP_NAME — tells it which nodemap you wanna hear about, by name. Skip it and you get all of them, no gatekeeping 💖 You can pair this with --property to pull the value of one specific property off one specific nodemap.
• --property PROPERTY_NAME — says which property's value you want to see. Don't specify it and, yep, all the properties get shown 🌈 You can run this alongside --name to get that one property for that one nodemap.
• --list — shows the global nodemap state and Lists all defined nodemaps plus the nodemap properties that are available 👑

---

# lctl nodemap_info --list
