I'm managing a Proxmox cluster running Bluestore Ceph, but I can't replicate the production environment without shelling out over $30K for a duplicate setup. I've got test environments and backups for everything else, but Ceph is more tricky. I've managed to create three VMs to simulate the cluster, but it's not quite the same as using physical hardware. What I really want to do is test if the cluster is hot-swappable. I'm particularly interested in what happens when I swap an HDD with an SSD, and how Ceph registers and unregisters OSDs in that process.

Have you thought about using tools like Copilot or ChatGPT for some insights? Or reach out to support! They might have guidance on whether your planned swap will work with your setup.
Honestly, testing this scenario without the right hardware setup is really tough. It's a classic situation where everyone says they have a test environment, but recreating a production one is rare.

I've already checked with support. They suggested either using Docker or VMs, but I didn't find that adequate. I've tried those options, so I'm not coming in without doing my homework!
