Abstract
According to one embodiment, in response to a request for verifying a first prime representing a consistent point of a file system of a storage system having a plurality of storage units, each of a plurality of prime segments collectively representing the first prime is examined to determine whether the corresponding prime segment has been previously verified. Each of the prime segments is stored in one of the storage units, respectively. At least a first of the prime segments that has not been previously verified is verified, without verifying a second of the prime segments that has been previously verified. The first prime, when at least the first prime segment has been successfully verified, can be used to construct the consistent point of the file system.
