Re: ceph -s slow return result

Are all your monitors running? Usually a temporary hang means that the Ceph client tries to reach a monitor that isn't up, then times out and contacts a different one.

I have also seen it just be slow if the monitors are processing so many updates that they're behind, but that's usually on a very unhappy cluster.

On my CEPH cluster, "ceph -s" return result quite slow.
Sometimes it return result immediately, sometimes i hang few seconds before return result. 

Do you think this problem (ceph -s slow return) only relate to ceph-mon(s) process? or maybe it relate to ceph-osd(s) too?
(i deleting a big bucket, .rgw.buckets, and ceph-osd(s) disk util quite high)
