I guess this has been asked before, I'm just new to the list and wondered whether it's possible to do rolling upgrades of mons, osds and radosgw? We will soon be in the process of migrating from our current storage solution to Ceph/RGW. We will only use the object storage, actually mainly the S3-interface radosgw supplies. Right now we have a very small test-installation - 1 mon, 2 osds where the mon also runs rgw. Next week I've heard that 0.48 might be released, if we upgrade to that, do we have to shut down the cluster during the upgrade or can we do a rolling upgrade while still responding to PUTs and GETs? If not possible yet, is this in the pipeline?
