ABSTRACT:
A high-reliability file system which surely keeps multiple file data on one drive even if some drives have failed. If renewal of a plurality of blocks of a disk by data in a buffer is necessary, a buffer manager renews the disk by all the data in the buffer which are to be renewed in the future. Flush management is carried out by the drive and the buffer manager. If another drive is "examining" or "renewing" when a flush (renewal) is to be executed, a sequencing means temporarily restrains the buffer manager from starting the flush.
