That's what I thought. We looked at the cluster storage nodes and found them all to be less than .2 normalized maximum load.
Our 'normal' BW for client IO according to ceph -s is around 60MB/s-100MB/s. I don't usually look at the IOPs so I don't have that number right now. We have seen GB/s numbers during repairs, so the cluster can get up there when the workload requires. We discovered that this system never got the auto repair setting configured to true and since we turned that on, we have been repairing PGs for the past 24 hours. So, maybe we've been bottlenecked by those?

You can use uptime command to get the current statistics. On 3/10/22 10:51 PM, Ray Cunningham wrote: > From: > > osd_scrub_load_threshold > The normalized maximum load.
