Ceph » rgw

• rgw_region_root_pool option should be in [global] section in ceph configuration file
  http://docs.ceph.com/docs/master/radosgw/federated-config/#add-instances-to-ceph-config-file

We need to change this in example given in above link.

As if we use rgw_region_root_pool in [radosgw] section with different pool name as compare to default it create issues for radosgw-admin region list command.

$radosgw-admin region list
failed to list regions: (2) No such file or directory
