Adding a Node to ceph tanks performance


Feb 13, 2022
I had a 3 node cluster where the command
rados bench -p scbench 10 write --no-cleanup
gets the following results

after adding another node however the results seem to have tanked.

I can obviously see the cur MB/s had a sharp drop, however Im not sure what is the issue and not even sure how to start debugging. Any help would be appreciated. Thanks

Could you measure the latency between nodes using `ping`?
