Review Comment: May be in brief we can explain in this way. ``` The combined total space Ozone is allowed to use across all configured storage directories on all live Datanodes in the cluster. This is the physical disk capacity minus the reserved space on each volume. ``` -- This is an automated message from the Apache Git Service.
