Description Yogev Rabl 2016-02-15 03:28:02 EST
Description of problem:
The installation of overcloud with external ceph requires few parameters in puppet-ceph-external.yaml: CephClusterFSID, CephClientKey, CephExternalMonHost, the names of the pools and Ceph user. 
The Ceph configuration file in the overcloud has configurations that are different from the configuration of the Ceph cluster.

For an example, this is the Ceph configuration of the overcloud:
osd_pool_default_pgp_num = 128 #can be changed in ../puppet/hieradata/ceph.yaml
osd_pool_default_min_size = 1 #can be changed in ../puppet/hieradata/ceph.yaml
auth_service_required = cephx
fsid = 792a0c5d-2f7d-4720-9232-d662de74fe6a
cluster_network = #irrelevant parameter in this case, remove/set different parameter in ceph-external.yaml
auth_supported = cephx
auth_cluster_required = cephx
mon_host =
auth_client_required = cephx
osd_pool_default_size = 3 #can be changed in ../puppet/hieradata/ceph.yaml
osd_pool_default_pg_num = 128 #can be changed in ../puppet/hieradata/ceph.yaml
public_network = #a there's a different parameter in the cluster's ceph.conf 

osd_journal_size = 1024 #can be changed in ../puppet/hieradata/ceph.yaml
Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Deploy an overcloud with puppet-external-ceph.yaml

Actual results:
The Ceph configuration on the Openstack controllers are different from the configuration in the Ceph cluster. 

Expected results:
The Ceph configuration file should be the same on both Openstack controllers and Ceph cluster.
