Thanks Stefan, i played with bluefs_buffered_io but i think the impact is not great since the nvmes are so fast. I think buffered IO on increased cpu load while buffered io off increase nvme load. Problem was with both settings. I am not sure if require-osd-release was run. What do you think ceph osd require-osd-release pacific will do and is there a risk when running the command that the cluster might become unavailable ? I think all osds are running 16.2.6 anyway and so it would not change anything if i set the force to run Pacific ?
