Problems solved by technology

[0003] Traditional cluster nodes usually use a local stand-alone file system, so that multiple cluster nodes share files and need to store data copies on each node, which is not only not conducive to information communication and update, but also causes waste of storage resources
The stand-alone file system is limited to local-level maintenance and management, lacks unified scheduling of cluster resources, and has high management costs. The stand-alone file system is also limited to single-point data disaster recovery capabilities, and lacks cluster-style failover / recovery capabilities
[0004] With the growing popularity of cluster applications and the increasingly large-scale development trend, the traditional local OS-level file system is no longer suitable for storage requirements

Embodiment Construction

[0043] See figure 1 , This figure shows a cluster shared storage pool method according to an embodiment of the present invention, including the steps:

[0044] Step S101: Configure the global file system (GFS) shared by the cluster based on the storage area network (SAN);

[0045] Step S102: each client node in the cluster mounts part of the partitions in the global file system locally as needed, and performs read and write operations on them;

[0046] Step S103: The global file system processes the read and write operations of each client node in the cluster in parallel.

[0047] When performing step S101, you can use figure 2 The method shown to configure the global file system:

[0048] Step S1011: Configure the physical storage raw device in the storage domain network as a logical storage volume group;

[0049] In specific implementation, the logical volume group management tool (LVM) can be used under the cluster node linux system to first configure the physical storage bare device...

Abstract

The invention provides a method, a device and a system for sharing a storage pool by a cluster. The method comprises the following steps of: configuring a global file system (GFS) to be shared by the cluster based on a storage area network (SAN), and processing reading-writing operations of each client node in the cluster in parallel; and mounting a part of subareas in the global file system to a local server for the reading-writing operations according to needs by using each client node in the cluster. In the method, a network level high-efficiency data sharing way is provided, the parallel file reading-writing of a plurality of users is supported, and flexible online capacity expansion and data equilibrium distribution technologies are supported.

Description

Technical field [0001] The invention relates to the field of cluster shared storage, in particular to a method, device and system for cluster shared storage pool. Background technique [0002] Shared storage pool is a cluster storage system that provides file sharing, parallel read and write, unified management and data disaster tolerance capabilities for the cluster. [0003] Traditional cluster nodes usually use a local single-machine file system, so that multiple cluster nodes need to store a copy of data in each node to share files, which is not only unfavorable for communication and updating of information, but also wastes storage resources. The stand-alone file system is limited to local-level maintenance and management, lacks the unified scheduling of cluster resources, and the management cost is high. The stand-alone file system is also limited to a single point of data disaster tolerance and lacks cluster-type failover / recovery capabilities. [0004] With the growing popula...
