Problems solved by technology

In addition, the two file systems provide the function of data parallel access, but there is no effective node access load balancing scheme
In increasingly large and complex storage network applications, there is a problem that frequent access nodes are prone to access bottlenecks and the utilization rate of local idle nodes is not high

Embodiment Construction

[0032] The object-based cluster file system management system includes system nodes, and the system nodes include nodes that undertake the function of managing objects; the management objects are used to monitor each system node and automatically balance the load of the system nodes.

[0033] The management object is also used to back up metadata objects and / or stored data objects on different system nodes; it is also used to judge whether a system node is an overloaded node or a non-operated node according to the service access processing capability, transmission capability and storage capacity of the system node. Overload node, transfer the service of metadata object on the overload node to the backup metadata object on the non-overload node, transfer the service of the storage data object on the overload node to the backup storage on the non-overload node on the data object.

[0034] Such as figure 1 As shown, in this system, different types of objects can be maintained on...

Abstract

The invention discloses an object-based cluster file system management method and a cluster file system. The method comprises the following steps of: arranging a management object in the cluster file system; and monitoring each system node by a management object and automatically configuring load of the system node in a balanced way. By separating a management object, a metadata object and a stored data object, flexible configuration and allocation of system resource unrelated to physical equipment are realized, and the load of the system node is automatically configured in the balanced way, so that the storing and the accessing of each object in the system is dynamically balanced, and data accessing bottleneck is eliminated; and adaptive functional extension and effective failure recovery are realized by object copying. Compared with the conventional cluster file system, the extensibility and the availability of the cluster file system are enhanced, the adaptive load balancing is realized, and the parallel processing capacity of the file system and the overall processing performance of the system are improved.

Description

technical field [0001] The invention relates to a cluster file system, in particular to an object-based cluster file system management method and the cluster file system. Background technique [0002] The file system is an important part of the operating system. By abstracting the storage space managed by the operating system, it provides users with a unified and object-oriented access interface, shielding the direct operation and resource management of physical devices. The file system can be divided into four levels, from low to high: the local file system of single processor and single user, such as the file system of DOSFS; the local file system of multiprocessor single user, such as the file system of OS / 2; Multi-processor multi-user file system, such as Unix local file system; multi-processor multi-user distributed file system. Distributed File System (Distributed File System) means that the physical storage resources managed by the file system are not necessarily dir...
