Ceph - Regarding Stopping IO while taking a snapshot

Solution Unverified - Updated -

Issue

I am trying to create a snapshot using librados functions.As per my knowledge I cannot or not advisable to create a snapshot unless and until all the IO operations are restricted.I want to automate the creation of snapshot, which will happen every 30 minutes.
But at the same time a lot of client instances will be creating IO context for read and write, so what can be done to stop those read and writes while snapshot creation.
How will the creation of snapshots will effect the efficiency of CEPH?
How can we effectively use snapshots ?
