Deployment of external ceph with UI: CephClusterFSID didn't get the right value. Environment: instack-undercloud-8.4.1-4.el7ost.noarch openstack-tripleo-heat-templates-8.0.2-29.el7ost.noarch openstack-tripleo-ui-8.3.1-2.el7ost.noarch Attempted external ceph deployment with UI. Included a yaml for external ceph deployment. CephClientKey, CephExternalMonHost fields got the right values. CephClusterFSID field didn't get the right value.
This sounds like https://bugs.launchpad.net/tripleo/+bug/1664521 (the fix is intricate and related to merging environments, and has been slowly worked on over the last few releases). In general when using the UI it's better to use the UI to set parameters. In OSP13, that would mean enabling the External Ceph environment in the overall settings (under Storage), and then modify CephClusterFSID in Parameters -> Externally Managed Ceph.
Can you please provide plan-environment.yaml and also check the parameter value in UI as Julie described above? I agree that most likely we're hitting the bug Julie referenced. Especially if you added custom environment file which carries the parameter value for CephClusterFSID (I can clearly ientify that if you provide plan-environment.yaml)
