openstack deploy command fails with error when intergrating ceph node with existing overcloud deployment

Solution In Progress - Updated -


  • We have an existing openstack overcloud deployment with which I want to integrate a ceph storage node. I make needful changes in ceph-ansible-external.yaml and give it as an environment file to the openstack deploy command like:
openstack overcloud deploy --templates /home/stack/openstack-tripleo-heat-templates/ -r /home/stack/openstack-tripleo-heat-templates/roles_data.yaml -e /home/stack/templates/node-info.yaml -e /home/stack/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e /home/stack/openstack-tripleo-heat-templates/environments/network-environment.yaml -e /home/stack/tripleo-config-generated-env-files/containers-prepare-parameter.yaml -e /home/stack/tripleo-config-generated-env-files/undercloud_parameters.yaml -e /home/stack/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible-external.yaml --ntp-server --libvirt-type kvm --log-file overcloud_deploy.log
  • We get the following error:
 ERROR openstack [  admin] The CephFSID environment value  (7c7129d3-8729-4457-965c-325f8fe793b8) does not match the stack  configuration value (0721b4bb-6198-40a3-952c-3f02a377e4fa). Ensure the CephClusterFSID  param is properly configured  in the storage environment  files.
  • Our ceph-ansible-external.yaml contains:
  OS::TripleO::Services::CephExternal: /home/stack/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible-external.yaml

  # NOTE: These example parameters are required when using CephExternal
  CephClusterFSID: '7c7129d3-8729-4457-965c-325f8fe793b8'
  CephClientKey: 'AQBmlqtgp5GINhAA/npRo863t9UtC+NiiCCVZA=='
  CephExternalMonHost: ''

  # the following parameters enable Ceph backends for Cinder, Glance, Gnocchi and Nova
  NovaEnableRbdBackend: false
  CinderEnableRbdBackend: true
  #CinderBackupBackend: ceph
  #GlanceBackend: rbd
  # Uncomment below if enabling legacy telemetry
  # GnocchiBackend: rbd
  # If the Ceph pools which host VMs, Volumes and Images do not match these
  # names OR the client keyring to use is not named 'openstack',  edit the
  # following as needed.
  #NovaRbdPoolName: vms
  CinderRbdPoolName: volumes
  #CinderBackupRbdPoolName: backups
  #GlanceRbdPoolName: images
  # Uncomment below if enabling legacy telemetry
  # GnocchiRbdPoolName: metrics
  CephClientUserName: cinder

  # finally we disable the Cinder LVM backend
  CinderEnableIscsiBackend: false
  • This issue occurs when openstack deploy command is triggered for ceph node integration with existing openstack overcloud deployment.
