  • 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.


  • Trump isn’t running again, he’ll be like 86, so he’s not going to give a shit what comes next.

    He’s not planning on running again. He’s planning on being king until he dies. Even if the GQP didn’t plan on doing everything that they laid out to turn the country into a theofascist dictatorship (they do plan on it), the courts will be irreparably compromised for the lifetime of everyone currently alive. Optimism would be nice but the very real consequences of 15million people sitting out this election is that it is the last real one that this country will see and the last one under which many will have civil rights.
