We have a ceph cluster of only nvme drives. Very recently our overall OSD write latency increase pretty dramatically and our overall thoughput has really decreased. One thing that seems to correlate with the start of this problem are the below ERROR line from the logs. All our OSD nodes are creating these log lines now. Can anyone tell me what this might be telling us? All and any help is greatly appreciated.
