If the creation timestamp of the FD is not changed, but the socket information to which the FD was linked is changed, it means new tcp connection is established. If there's no reading/wring ongoing, why new tcp connection is still established and the FD count is stable?
Though I am just a ceph user not the expert, but I think each block device as the client who is involved into CRUSH algorithm for data rebalancing etc, so long connections between client and OSDs are kept.
