Yesterday, after the business hours, I tried to do what you said. I stopped all managers, then on the third node: pveceph createmon --exclude-manager 1 Ceph was unhealthy because of no manager active, but all the three monitors were active and in quorum without problems. After about an hour...

I made a pveceph init only on one node, for the creation of the ceph cluster. Then I did as you say a pveceph createmon on each node. After that, I started adding OSDs, and that was working for about a week (ceph -s was saying HEALTH_OK) To make a test, I removed all OSDs (pveceph destroyosd)...
