💖 ceph-crush-location — get CRUSH location 💖

okay so bestie, this is ceph-crush-location(1), a little User Commands moment, and honestly it's giving "tiny tool, huge main character energy" ✨

🌸 NAME 🌸

ceph-crush-location — get the CRUSH location, no cap 💅

🦋 DESCRIPTION 🦋

So basically, this generates a CRUSH location for whatever entity you throw at it. That's the whole vibe. 🫶

The CRUSH location is literally a list of key=value pairs, all separated by spaces, all squished onto a single line. It tells you where in the CRUSH hierarchy this entity should be placed — like a little home address but for your cluster's brain 🌈

✨ OPTIONS ✨

  • --cluster <clustername> — the name of the cluster, fr fr. (peep /etc/ceph/$cluster.conf for the tea 👀)
  • --type <osd|mds|client> — the daemon/entity type. pick your fighter: osd, mds, or client 💖
  • --id <id> — the id, bestie. that's the osd number, the mds name, or the client name, depending on what you said for --type ✨
