NOTE: In the normal situation, the capacity displays show you the space that is consumed by provisioning (e.g. CPGs, Volumes, and underlying LDs) and the space that is reserved by the system for spares. When chunklets or PDs fail, the data that was on those chunklets is moved onto the spares. The total amount of space consumed by provisioning does not change, nor does the total amount of spares in the system. However, there is an overlap in the numbers because the used spares are counted in the total number of spares (total spares = unused + used spares) AND in the provisioning (because parts of the LDs/CPGs/Volumes) are now using those spares. In this case, an asterisk (*) appears to indicate that the numbers will not add up due to this shared space.
