Embodiment Construction
[0039] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following will further explain the autonomous block management of a light-weight data-intensive file system proposed by the present invention in combination with diagrams and specific embodiments method.
[0040] A lightweight autonomous block management method for data-intensive file systems, which implements the mapping from data blocks to data nodes and from data nodes to data blocks through a set of reversible mathematical functions. Such as figure 2 As shown, the division of the specific functions of each node in the present invention: the master node is only responsible for the maintenance of the system namespace, the distribution of data blocks to data storage nodes, and the management of each data storage node; each data storage node is responsible for the consistency check of data blocks, Data block recovery and mapping informat...
