LLOBDSTAT(8)

💅 LLOBDSTAT — ok so this is the OST stats girly

Welcome to llobdstat, bestie. Yes it's section 8, yes it's a Lustre Configuration Utility, and yes she is literally just gonna sit there and tell you what your OST is doing. 🦋

✨ NAME ✨

llobdstat — display OST statistics 📊

---

🌸 SYNOPSIS 🌸

llobdstat ost_name [interval]

---

💖 DESCRIPTION 💖

Okay so here's the vibe: llobdstat prints out a line of OST statistics for the OST you name, and it does it every INTERVAL seconds. That's it. That's the whole job. 🫶

Run it directly on an OSS node — like, that's where it belongs, that's its home, don't make it commute. 🏠

And when you're done staring at numbers (which, valid), hit Ctrl+C to stop the statistics printing. Not me holding down the terminal forever 💀

Here's her in her natural habitat, fr fr:

...

Quick glossary moment so you're not lost: the note line up there is telling you cx = create, dx = destroy, st = statfs, pu = punch. Iykyk, but now you know anyway. 💅

And notice how it just keeps scrolling? That's the INTERVAL doing its thing, dropping a fresh row every tick. Iconic. ✨
