MiniCylpack - MC .... is the process used by Teradata filesystem to freeup space. It frees exactly one cylinder. It is the last step system can take in order to recover space for writing data. Teradata DB file-system starts this process when number of free cylinders drops to the value of MiniCylPackLowCylProd.
