Hi,
No, when an OSD or a MON service starts it fetches its local /etc/ceph/ceph.conf file. So, as Matt stated, you need to deploy your updated ceph.conf on all the nodes.
Indeed, services contact the MONs, but it is mainly to retrieve the crushmap.

HI Matt,
Thank you..
But - what I understood is - ceph osd service restart will pickup the
cephconf from the monitor node.
Is this understanding correct?
Thanks
