Abstract:
1. A method for verifying a replicated file system, the method comprising: generating a source signature dataset using a host computer system of a data storage environment by traversing through source data blocks of a source file system in such a way that the source signature dataset comprises, for each source data block, a fingerprint of the source data block and a space allocation for the source data block; generating a target signature dataset using the host computer system by traversing through target data blocks of a target file system in such a way that the target signature dataset comprises, for each target data block, a fingerprint of the target data block and a space allocation for the target data block; and verifying that the target file system is a valid replica of the source file system using the host computer system by verifying the fingerprint and the space allocation for each target data block according to the fingerprint and the space allocation for each respective source data block.
