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

Your system is indeed slow, benchmark results are still not here ;)
