Folks, Today i found ceph -s is really slow and just hanging for minute or 2 minute to give me output also same with "ceph osd tree" output, command just hanging long time to give me output.. This is what i am seeing output, one OSD down not sure why its down and what is the relation with command running slow? I am also seeing what does that means?
