🌸 SYNOPSIS 🌸

ceph-rbdnamer num

🦋 DESCRIPTION 🦋

okay so picture this: you've got an RBD device and udev is just standing there like 👁️👄👁️ not knowing what to call it. enter ceph-rbdnamer. it takes the RBD device and prints out the pool, namespace, image, and snapshot names for that device straight to stdout. periodt.

who's it for? the udev device manager, bestie — it uses this so it can set up the RBD device symlinks and honestly? iconic of udev. the appropriate udev rules live in a file named 50-rbd.rules, so if you're out here wondering where those live, that's the one 🔥

it's giving "small tool, huge responsibility." main character energy fr fr.
