ABSTRACT:
A file system may save dirty file information indicating portions of files, residing on a storage system, to be modified corresponding data modification requests received by the file system. The file system may update the saved dirty file information to indicate successful modification of the files across redundant storage of the storage system and may track redundancy consistency recovery information on a file-by-file basis or on a file portion basis. A file system may also retrieve saved dirty file information and recover redundancy consistency for portions of files determined, based on the saved dirty file information, not to have redundancy consistency on the storage system. Recovering redundancy consistency may include copying, either directly to via a storage system mechanism, portions of files between redundant storage of the storage system. The redundancy consistency for the saved dirty file information may be recovered prior to recovering redundancy consistency for individual files.
