Ceph configuration

IBM Storage Ceph clusters typically have a configuration file that is created and defined through a deployment tool. Configuration files can also be created manually.

Deployment tools, such as cephadm, typically create an initial Ceph configuration file for you. However, you can manually create one, if you prefer to bootstrap an IBM Storage Ceph cluster without using a deployment tool.

IBM Storage Ceph clusters have a configuration, which defines:
  • Cluster Identity
  • Authentication settings
  • Ceph daemons
  • Network configuration
  • Node names and addresses
  • Paths to keyrings
  • Paths to OSD log files
  • Other runtime options
