Hi Song, Next time, please post the question in ceph-devel or ceph-users mailing list. I'm also replying the answer to your question to the ceph-users maling list. The purpose of "--delay SEC" is to protect the image from being accidentally removed from trash before SEC is expired, and to allow some automatic process (a cron job for instance) to remove the image from trash after its delay is expired.
