Abstract
A system and method for detecting buffer leaks in a files system utilizing consistency points is provided. Upon receipt of a write operation, a buffer check control structure is written to a raw data buffer. The buffer check control structure comprises a set of magic numbers and a consistency point counter identifying the current CP. At write allocation time, the buffer check control structure is examined to determine that the buffer is being committed to disk during the correct CP.
