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 msgr2
And this is reflected in the monmap:
monmaptool: monmap file /tmp/monmap
epoch 7
fsid 7273720d-04d7-480f-a77c-f0207ae35852

6: [v2:172.30.0.150:3300/0,v1:172.30.0.150:6789/0] mon.node07.homeflow.co.uk
I 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 !
