OK it's explain here https://docs.ceph.com/en/pacific/rados/configuration/common/#running-multiple-clusters-deprecated:
But at https://docs.ceph.com/en/pacific/install/manual-deployment/:
Cluster Name: Ceph clusters have a cluster name, which is a simple string without spaces. The default cluster name is ceph, but you may specify a different cluster name. Overriding the default cluster name is especially useful when you are working with multiple clusters and you need to clearly understand which cluster your are working with.
For example, when you run multiple clusters in a multisite configuration <https://docs.ceph.com/en/pacific/radosgw/multisite/#multisite>, the cluster name (e.g., us-west, us-east) identifies the cluster for the current CLI session. Note: To identify the cluster name on the command line interface, specify the Ceph configuration file with the cluster name (e.g., ceph.conf, us-west.conf, us-east.conf, etc.). Also see CLI usage (ceph --cluster {cluster-name}).
And many other places. So that paragraph is a documentation bug.
