What is the true way of configuring DNS records for ceph?

public network = 10.17.12.0/24
cluster network = 10.17.27.0/24

Storages have separate interfaces for public and cluster networks.

In DNS servers I added records such as storage01 pointing to IPs in public network.

Do I need to add extra records which will point to cluster network?

Do I need to add records to /etc/hosts file on storages to make storages resolve each other to cluster network addresses?

Or maybe I don`t need to care about cluster network and ceph will determine cluster network addresses himself without asking DNS and /etc/hosts?

Do monitors interact with OSD using public network?

Do I need to add cluster network to monitors?
