Hi All,
I have a repeatable condition when the object count in a pool gets to 320-330 million the object write time dramatically and almost instantly increases as much as 10X, exhibited by fs_apply_latency going from 10ms to 100s of ms.
Can someone point me in a direction / have an explanation ?
I can add a new pool and it performs normally.
Config is generally
3 Nodes 24 physical core each, 768GB Ram each, 16 OSD / node , all SSD with NVME for journals. Centos 7.2, XFS
Jewell is the release; inserting objects with librados via some Python test code.
Best Regards
Wade
