Yeah, msgr2 still makes some problems sometimes.
Try to (re-)run "ceph mon enable-msgr2" and if that doesn't help i'd just delete and re-create the mon (usually way easier than playing around with the mon map manually).

Hi. Firstly thanks to all involved in this great mailing list, I learn lots from it every day._______________________________________________We are running Ceph with a huge amount of success to store website themes/templates across a large collection of websites. We are very pleased with the solution in every way.The only issue we have, which we have had since day 1, is we always see HEALTH_WARN:health: HEALTH_WARN
1 monitors have not enabled msgr2And this is reflected in the monmap:monmaptool: monmap file /tmp/monmap

6: [v2:172.30.0.150:3300/0,v1:172.30.0.150:6789/0] mon.node07.homeflow.co.ukI never figured out the correct syntax to set up the first monitor to use both 6789 and 3300. The other monitors that join the cluster set this config automatically but I couldn't work out how to apply it to the first monitor node.The cluster has been operating in production for at least a month now with no issues at all, so it would be nice to remove this warning as, at the moment, it's not really very useful as a monitoring metric.Could somebody advise me on the safest/most sensible way to update the monmap so that node01 listens on v2 and v1 ?Thanks for any help !
