    摘要: An alarm method for insufficient storage space of a network storage system is provided. The method includes the following steps. Preset a time alarm threshold value according to a current operation state of the system when allocating storage spaces to users. Estimate a time that written data fully occupy a current remaining space according to a data writing speed to the storage space, a current idle memory of the system, total dirty data in a cache of the system, and the current remaining space in the storage space. Compare the estimated time value and the time alarm threshold value. And, send alarm information when the estimated time value is smaller than the time alarm threshold value. By setting the alarm threshold value of a time concept, a timely alarm of insufficient storage space is realized, which enhances the effective management of the storage space.

    摘要: A method of automatically adjusting a size of a copy-on-write (COW) disk space of a snapshot device is provided. A first disk space of a snapshot device is initialized, and a COW operation is performed on a chunk of the first disk space. Next, it is determined whether a chunk sequence number of a write request is in the first disk space. Then, if the chuck sequence number of the write request is in the first disk space, the first disk space is maintained. Then, if the chuck sequence number of the write request is not in the first disk space, a second disk space is initialized, and the number of chunks of the second disk space is the same as the number of maximum successive chunks of the first disk space, and then, the COW operation is performed on the chunk of the second disk space.

    摘要: A system of protecting data in write-back cache between storage systems and the method thereof are employed to protect data in the write-back cache between a first storage system and a second storage system. The system adds, updates, or deletes the data in the second storage system backed up from the write-back cache of the first storage system by monitoring operations on the write-back cache of the first storage system and sending a corresponding command to the second storage system in accord with the monitored operation. Therefore, the method ensures the consistency between the backup data and the data stored in the write-back cache of the first storage system, thereby increasing the security of the data.

    摘要: A method of protecting data in the cache memory of a storage system is used to protect the data stored in the cache memory of a first storage system and a second storage system coupled together and with the battery backed function. When the first storage system and the second storage system function normally, the data in their cache memory are mutually backed up. When any of the storage system has a power failure situation, the other normal storage system takes over the malfunctioned storage device. The data in its own cache memory are protected using the battery backed function. After the malfunctioned storage system restarts, the two storage systems keep backing up the data in the cache memory of each other. This provides a thorough protection of the data in the cache memory of the storage systems, increasing the reliability thereof.

    摘要: A method of protecting the cache memory data in a storage system is used to protect the data in the cache memory of a battery backed storage system. The method provides a preserved area in the random access memory (RAM) of the system for storing the information of disk cache items. When the storage system has a power failure, the battery backed function provides power to protect the data stored in the RAM of the system being lost. When the storage system resumes, the information stored in the preserved area preserves the data stored in the disk cache of the system RAM. After the storage system resumes, the data stored in the disk cache of the RAM of the system are written into the corresponding block device. These implement the power failure protection for the data stored in the disk cache of the RAM of the system.

    摘要: A method for installing EXT (extended) file system from a server to at least a client, the method includes the following steps. The super blocks of original files in a server are read to obtain subarea basic parameters of original files which are then packed into an image file. The reserved nodes and the first data pointing to the reserved nodes are analyzed in sequence. Whether the reserved nodes point to directory files is judged. A directory sequence is created according to the judge result. The nodes and the first data pointing to the nodes is reviewed. A client receives the image file and separates the subarea basic parameters of original files and data blocks from the image file, and calculates the basic data and data blocks for storing them in the client.
