7.6. Modifying Advanced Ceph Settings

The installer provides you with a set of advanced configuration options to manually define aspects of your OpenStack Platform environment. This includes settings for Red Hat Ceph Storage. These advanced settings allow you to integrate your new OpenStack Platform environment with an existing Ceph Storage cluster.

Note

Refer to the /etc/ceph/ceph.conf file from your existing Ceph cluster for settings to use in the Advanced Configuration section.

Important

It is recommended to leave these settings as defaults when creating a new Ceph cluster configuration through the installer.
Use the following procedure to modify your Ceph settings.

    • Ceph fsid - The Ceph filesystem ID to use.
    • Ceph images key - The key to use for image authentication.
    • Ceph mon host - An array of monitor hosts. For example:
      ["ceph1.example.com","ceph2.example.com","ceph3.example.com"]
      
    • Ceph mon initial members - An array of initial monitor hosts to establish a quorum. For example:
      ["ceph1.example.com","ceph2.example.com"]
      
    • Ceph volumes key - The key to use for volume authentication.
  4. Choose the Neutron-compute service. Scroll to the following settings and edit them as required:
