      Description

      columnstore_info.total_usage() returns irrelevant value

      after loading 1TB data, columnstore_info.total_usage() returns
      TOTAL_DISK_USAGE of 34.01 GB
      while Disk usage on PM1 DBRoot 1 is 361G .

      on mcs installation from scratch on 2 mcs modules(1um-1pm), load 1 TB data
      get columnstore_info.total_usage()

      From PM1, the disk usage on DBRoot 1 :
      361G    /usr/local/mariadb/columnstore/data1
      

      MariaDB [(none)]> call columnstore_info.total_usage();
