When checking the amount of disk space available for a svm (nfs) volume the numbers don't seem to add up. These are the numbers reported by the api:

         "size" => 10995116277760,

         "expected_available" => 649073881088,
         "filesystem_size" => 10995116277760,
         "filesystem_size_fixed" => false,
         "large_size_enabled" => false,
         "logical_space" => [
           "reporting" => false,
           "enforcement" => false,
           "used_by_afs" => 13149514948608,
           "used_percent" => 179,

           "used_by_snapshots" => 0,
         ],

percent_used is 72 but available_percent is 5. How much actual space is left so we can ensure a new volume will fit?

Looks like the %72 is the % used of "space available for snapshots", the "Physical used" is %94, which tracks with the %5 available.
