RBD-REPLAY-PREP(8)

✨ RBD-REPLAY-PREP ✨

okay bestie, welcome to the rbd-replay-prep page, aka section 8 of the Ceph manual, aka the little tool that gets your captured RBD workload all dressed up and ready to be replayed 💅

🌸 NAME 🌸

rbd-replay-prep — prepare captured rados block device (RBD) workloads for replay 🎀

🦋 SYNOPSIS 🦋

rbd-replay-prep [ --window seconds ] [ --anonymize ] trace_dir replay_file

💖 DESCRIPTION 💖

so basically, rbd-replay-prep takes your raw rados block device (RBD) traces and processes them so they're all prepped and presentable for rbd-replay. it's the glow-up era of your trace files, no cap ✨

👑 OPTIONS 👑

• --window seconds — requests that are further apart than seconds seconds get treated as independent. like, they're not vibing together anymore, they're doing their own thing 🫶
• --anonymize — anonymizes image and snap names. your names stay lowkey, nobody's business 🙈
• --verbose — prints all processed events to the console. it's giving main character energy, everything gets a shoutout 🔥

🍓 EXAMPLES 🍓

to prepare workload1-trace for replay, you'd literally just do this:

rbd-replay-prep workload1-trace/ust/uid/1000/64-bit workload1

🌈 AVAILABILITY 🌈

rbd-replay-prep is part of Ceph, a massively scalable, open-source, distributed storage system. for more info, go check the Ceph documentation at <https://docs.ceph.com> — it's iconic, fr fr ⭐
