Hi We've got a three node ceph cluster, and radosgw on a fourth machine. We would like to add another radosgw machine for high availability. Here are a few questions I have: - We aren't expecting to deploy to multiple regions and zones anywhere soon. So presumably, we do not have to worry about federated deployment. Would it be hard to move to a federated deployment later? - What is a radosgw instance? I was guessing that it was a machine running radosgw. If not, is it a separate gateway with a separate set of user and pools, possibly running on the same machine? - Can I simply deploy another radosgw machine with the same configuration as the first one? If the second interpretation is true, I guess I could. - Am I right that all gateway users go in the same keyring, which is copied to all the gateway nodes and all the monitor nodes? - The gateway nodes obviously need a [client.radosgw.{instance-name}] stanza in /etc/ceph.conf. Do the monitor nodes also need a copy of the stanza? - Do the gateway nodes need all of the monitors' [global] stanza in their /etc/ceph.conf? Presumably, they at least need mon_host to know who to talk to. What else? Regards Jon Jon K?re Hellan, UNINETT AS, Trondheim, Norway
