Description of problem:

The Director Installation and Configuration guide instructs the operator to add the parameter_defaults section to the storage-environment.yaml file.  See here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html-single/Director_Installation_and_Usage/index.html#sect-Advanced-Scenario_3_Using_the_CLI_to_Create_an_Advanced_Overcloud_with_Ceph_Nodes

The following stanza should just be part of the file, not manually added by the operator:

parameter_defaults:
  ExtraConfig:
    ceph::profile::params::osds:

# Example: separate OSD disks with journal devices on a single disk
#
#        '/dev/sdc':
#          journal: '/dev/sdb1'
#        '/dev/sdd':
#          journal: '/dev/sdb2'
#
# Example: jco-located ournals on the OSD disks
#
#        '/dev/sdb': {}
#        '/dev/sdc': {}
#        '/dev/sdd': {}
