# Allows for you to define pools for whatever group you wish such as 'radosgw' or 'rbd' or both.
# There is a pools.rb attribute that sets default pool names based on pool types ('radosgw', 'rbd')
# along with settings for each. The settings are applied to ALL pool names in the given list for the given type.
# All of those values can be overridden using the override_attributes in your environment.yaml file.

  node['ceph']['pools']['active'].each do |pool|
    # Create pool and set type (replicated or erasure - default is replicated)
    if pool == 'radosgw' && !node['ceph']['pools']['radosgw']['federated_regions'].empty? && node['ceph']['pools']['radosgw']['federated_enable']
      # NOTE: *Must* have federated_regions and federated_zones if doing any federated processing!
      ceph_chef_build_federated_pool(pool)

    # If federation is not used then the standard pool names and settings will be used.
