[ceph-users] Terrible IOPS performance

Hi folks, I have a three-node cluster on a 10G network with very little traffic. I have a six-OSD flash-only pool with two devices — a 1TB NVMe drive and a 256GB SATA SSD — on each node, and here’s how it benchmarks: Oof. How can I troubleshoot this? Anthony mentioned that I might be able to run more than one OSD on the NVMe — how is that done, and can I do it “on the fly” with the system already up and running like this? And, will more OSDs give me better IOPS? Thanks, Jarett
