  • I maintained a CEPH cluster a few years back. I can verify that speeds under 10GbE will cause a lot of weird issues. Ideally, you’ll even want a dedicated 10GbE purely for CEPH to do its automatic maintenance stuff and not impact storage clients.

    The PGs is a separate issue. Each PG is like a disk partition. There’s some funky math and guidelines to calculate the ideal number for each pool, based upon disks, OSDs, capacity, replicas, etc. Basically, more PGs means that there are more (but smaller) places for CEPH to store data. This means that balancing over a larger number of nodes and drives is easier. It also means that there’s more metadata to track. So, really, it’s a bit of a balancing act.

    I surely will and there’s no shame in it or any other expression of sorrow by a man, woman, or enbie. I’m afraid, however, that I have neither the patience, nor ability to give you empathy for those that are currently are and will soon be suffering and dying because of people who care more about their own moral purity than other human beings. If you’re unable to reach that capacity on your own, maybe therapy would be a good option (many professionals offer sliding scales, so if you have a challenge with that, I’d be happy to try to help you find someone in your area that could help).
