clustergroup

Adds, deletes and updates clusters from cluster groups/global namespace.

A global namespace stitches multiple data sources into a single accessible entity and provides multiple data access points, where each access point shows the same hierarchical namespace. The entire group of data sources could be accessed and operated by using any one of the access points, without any need to know the source's physical data location.

The global namespace is implemented using clustergroup command.

The following example shows the clustergroup command-line help:
