CEPH Nautilus mon_host in [global] vs mon_host in [client]

[Mihai]

At this time, here is the way monitors are registered in ceph.conf (an excerpt only):

[client]
[mon.VMHost4]
         host = VMHost4
         mon addr = 10.10.1.14:6789

[mon.VMHost3]
         host = VMHost3
         mon addr = 10.10.1.13:6789

[mon.VMHost2]
         host = VMHost2
         mon addr = 10.10.1.16:6789

If I understand correctly, the new method in Nautilus is to use:

[global]
mon_host = 10.10.1.13 10.10.1.14 10.10.1.16

What is the proper way to edit the ceph.conf

Can I just edit the mon_addr = and remove the port number? Should I remove the monitors from the [client] section altogether? Should I leave both in there?

you can leave both there, but it is better to have it only in one place

you can find more info about this in the official ceph documentation https://docs.ceph.com/docs/nautilus/rados/configuration/msgr2/#msgr2-ceph-conf
