We just upgraded our last cluster to Luminous. Since we might need to renumber our mons in the not-too-distant future, it would be nice to remove the literal IP addresses of the mons from ceph.conf. Kraken and above support a DNS-based mechanism for this based on SRV records[1].
Unfortunately our Rados cluster is IPv6-based, and in testing we found out that the code that resolves these SRV records only looks for IPv4 addresses (A records) of the hostnames that the SRVs point to. I just created issue #23078[2] for this. The description points to where I think the code would need to be changed. If I can do anything to help (in particular test fixes), please let me know. This might be relevant to others who run IPv6 Rados clusters. -- Simon.
