Abstract
A system and method for performing a distributed consistency check of a clustered file system. File system functions for loading an inode and/or buffer tree are modified so that in response to either of these functions being invoked, a consistency check is performed. The consistency check verifies both local consistency on a node of the clustered file and a distributed check across the nodes of the storage system.
