Out of curiosity, how DNS lookup [1] works with v2 only mons? Since we can’t specify whether the port is v1 or v2 in SRV records. Or it just works if I specify 3300 port in SRV records?

Previous to this we were binding to both 6789 and 3300. All of our server and client components are sufficiently new (14.2.x) and we haven’t observed any disruption but I am inquiring if this may be problematic for any unforeseen reason. We don’t intend to have any older clients connecting. https://docs.ceph.com/en/latest/rados/configuration/msgr2/ doesn’t mention much about running with only v2 so I just want to make sure we aren’t setting ourselves up for trouble. Thanks. No, not really. I have a couple of those servers as well where v1 was disabled completely.
