Abstract: A method for maintaining a file system of a computer system is disclosed. An operating system is loaded to the computer system when the computer system is booted, such that the file system of the computer system is monitored in real time after the computer system is booted. When occurrence of an error in the file system is detected, a number of times the error has occurred is accumulated. When the number of times the error has occurred reaches a predetermined threshold, a notification message is generated and displayed on an electronic apparatus. Accordingly, a manager of the computer system may be notified immediately when the occurrence of the error in the file system is detected.

Abstract: A method for performing data recovery in a redundant storage system and an associated apparatus are provided. The method includes: sending at least one basic command from a specific layer in a plurality layers of the redundant storage system to a lower layer of the specific layer, in which the basic command includes a read command, and the read command is used for requesting the lower layer to return a data block corresponding to an index; and sending at least one additional command from the specific layer to the lower layer, in which the additional command includes a read retry command, and the read retry command is used for requesting the lower layer to return a redundant data block corresponding to the index, for recovering the data block. The bottommost layer includes at least one set of storage devices.

Abstract: A method for performing data recovery in a redundant storage system and an associated apparatus are provided. The method includes: determining a state of a cache block of a plurality of cache blocks, in which the plurality of storage devices includes a set of Hard Disk Drives (HDDs) and a set of Solid State Drives (SSDs), an SSD Redundant Array of Independent Disk (RAID) of the redundant storage system includes the set of SSDs, and an HDD RAID of the redundant storage system includes the set of HDDs, in which the SSD RAID is utilized as a cache system of the HDD RAID and includes the plurality of cache blocks; and performing a retry-read operation on at least one of the HDD RAID and the SSD RAID according to the state of the cache block, to obtain a correct version of data within the redundant storage system.
