Embodiment 1

[0028] figure 1 It is a flow chart of a dynamic cloud storage method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of cloud storage of data. The method can be executed by a cloud storage system, and specifically includes the following steps:

[0029] Step S110, loading the metadata file into the first memory of the metadata server to form a memory directory tree, and organize message module data according to a preset data structure based on the memory directory tree.

[0030] After the metadata server starts, it loads the local metadata files into its own memory to form a memory directory tree, and at the same time organizes the data into the data structure required in the message module, and provides a read-only file directory to the outside world.

[0031] Among them, the HDFS cluster has two kinds of nodes, which run in the mode of manager-worker, that is, a name node (NameNode) and multiple data nodes (DataNode). Among them, ...

Embodiment 2

[0041] Figure 5 It is a flowchart of a dynamic cloud storage method provided by Embodiment 2 of the present invention. This embodiment is applicable to the case of cloud storage of data. The method can be executed by a cloud storage system, and specifically includes the following steps:

[0042] Step S210, configure the information of each physical node in the cloud storage platform through a configuration file.

[0043] Use the configuration file to configure the information of each physical node in the HDFS cluster. After completing the configuration, start the HDFS cluster.

[0044] Step S220, checking the startup status of the metadata server and the storage device management server.

[0045] Among them, after the HDFS cluster is started, the metadata server and the storage device management server start separately. At the same time, no matter whether the metadata server is started or the storage device management server is started, they will check each other's startup s...

Embodiment 3

[0061] Figure 6 A schematic structural diagram of a dynamic cloud storage system provided by Embodiment 3 of the present invention. This embodiment is applicable to cloud storage of data. The dynamic cloud storage system 310 specifically includes: a loading organization module 320 and a synchronization module 330 and update module 340 .

[0062] The entire secure cloud storage system consists of three parts: metadata server, storage device management server, and data storage server. The structural diagram of the entire secure cloud storage system is shown in Figure 7 shown. Wherein, the metadata server 401 is in the safe user enterprise space 405, and the user 404 directly interacts with the metadata server 401; the storage device management server 402 and the data storage server 403 are in the cloud storage space, and the storage device management server 402 directly communicates with the data storage server 403 performs communication interaction, and the storage device m...

Abstract

The invention discloses a dynamic cloud storage method and system. The method comprises the following steps: loading a metadata file in a first memory of a metadata server to form a memory directory tree, and organizing message module data according to a preset data structure based on the memory directory tree; synchronizing the message module data in a second memory of a storage device management server in a message transmission manner; and when the storage device management server accomplishes storage information collection of a cloud storage platform, updating the message module data in the second memory, and synchronizing the message module data to the metadata server in a memory sharing manner. The invention provides a shared data consistency keeping strategy, the data management of the metadata server is enhanced, and the communication process between the metadata server and the storage device management server is optimized to solve the problems of low transmission efficiency and poor shared data security, the overall cloud storage reading and writing efficiency and the cloud storage data security performance are improved, and the safe and stable operation of the whole cloud storage system is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to cloud storage technologies, and in particular to a dynamic cloud storage method and system. Background technique [0002] Cloud computing is a service that uses virtualization technology to provide users with dynamically scalable shared hardware and software resources through the Internet. The dynamic and elastic characteristics of cloud computing enable users to use and pay according to the number of used resources. Users can dynamically adjust resource usage according to the current service load to reduce resource waste. Cloud storage system is an important part of cloud computing system. From a technical point of view, the cloud storage system is actually a large-scale distributed network storage system, which is a special kind of shared storage. Users are provided with a special storage service that is paid on demand. [0003] As the underlying file system foundation of many Hadoop projects, the HDF...
