.Users can set the crush location for a Ceph Monitor to replace tiebreaker monitors With this release, users can set the crush location for a monitor deployed on a host. It should be assigned in the mon specification file. .Example ---- service_type: mon service_name: mon placement: hosts: - host1 - host2 - host3 spec: crush_locations: host1: - datacenter=a host2: - datacenter=b - rack=2 host3: - datacenter=a ---- This is primarily added to make the replacing of a tiebreaker monitor daemon in stretch clusters deployed by Cephadm, more feasible. Without this change, users would have to manually edit the files written by Cephadm to deploy the tiebreaker monitor, as the tiebreaker monitor is not allowed to join without declaring its crush location.
