Rebuilding a Namespace
By default, this stops all modifications (client writes and file renames on import) in all
managed volumes after the rebuild. Essentially, the nsck utility issues a

To guarantee that managed-volume modifications are enabled after the rebuild, run the

The nsck rebuild utility completely rebuilds all managed volumes in a namespace: it
re-imports the back-end shares and rebuilds its metadata databases. This command

The CLI prompts for confirmation before re-importing all managed volumes in the
namespace: enter yes to continue. Enter no to cancel the rebuild.
You can run one nsck job at a time on a given namespace. Use
the progress of nsck jobs; see

For example, the following command sequence exits to priv-exec mode and rebuilds
the 'wwmed' namespace.
