Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a file storage method of a distributed storage system according to an embodiment of the present application, where the method includes:
s101: receiving a storage request; the storage request comprises at least one of a file storage requirement, a block storage requirement and an object storage requirement;
s102: determining a corresponding data layer in the data layers of the storage cluster according to the storage request; the data layer comprises a file storage pool, a block storage pool and an object storage pool;
s103: and executing the corresponding file storage operation in the storage pool of the data layer according to the storage request.
The structure of the storage cluster provided by the present application is first described below, referring to fig. 2, fig. 2 is a schematic diagram of a storage cluster structure provided by the present application, and a series of configuration of cluster basic information, such as network settings, etc., are used to generate basic resources required by a cluster, such as a network, a cluster management tool, osd resources, etc., and on this basis, the initialization operation of file, object, and block scenes is completed, resources are allocated to the storage pools of each scene for use, and the storage pools provide data services for upper layer applications. The object storage general application scene is the storage of picture, video and other unstructured data; the file storage is generally used for storing files with directory structures such as FTP (file transfer protocol), NFS (network file system) and the like, so that the files can be conveniently shared and used; block storage is generally used for container or virtual machine disk storage allocation, and the read-write efficiency is improved through a combined logical disk. Various application scenarios use a standard protocol interface to access the stored data by calling corresponding services provided by the storage cluster. In a fusion scene, each storage pool can be conveniently and uniformly managed, for example, along with the gradual development of services, the data storage requirements change, for example, the data volume of a block service for structured data storage is reduced, the data of an unstructured form such as a file service or a video is increased, the storage pools of corresponding scenes can be expanded and contracted according to the service requirements, and the use of resources can be dynamically adjusted, so that the waste of resources and the repeated investment are avoided.
In generating the system shown in fig. 2, three steps may be included as follows:
firstly, configuring node information and node network information of nodes to be grouped in a configuration file;
secondly, configuring cluster management tools, cluster monitoring service, disk use setting, network setting and time setting to obtain an initialized storage cluster;
and thirdly, calling a background deployment interface to deploy the storage cluster.
Specifically, the basic resource deployment of the cluster is generally performed through the IP minimum node, and first, the IP and the host name of the node to be formed into the cluster, the bond type of the node network, the network card, the gateway, and the mask information need to be configured in the/etc/hosts configuration file.
And secondly, configuring a cluster management tool, wherein the infrastructure is used as the cluster management tool, the concurrent operation of the nodes in the distributed storage cluster is simple and convenient, and the host names of the nodes in the cluster are configured/etc/infrastructure/hosts and are synchronized to other nodes, so that the cluster management tool can be used.
The MON node belongs to a monitoring service node of a cluster, monitoring services need to be configured at a plurality of nodes in order to ensure that the MON has no single point fault, the configured monitoring services need to call an icfs-deployment interface, and the MON service is set; the SSD partition is used for reasonably planning the use of the SSD, and can generate osd on the partition of the SSD and can be used as db partitions of the osd and the HDD disk; the disk setting is used for selecting the disk of each node in the cluster to be used as the generated osd resource; the network is set for dividing network segments for use, for example, a management network is used for a distributed storage management software system, a public network is used for a third party such as OpenStack or a user, and a cluster network is used for internal communication of an osd cluster at the bottom layer of a storage engine; the time setting is used for setting the system time of the deployed nodes as a reference value and keeping the other nodes of the cluster in clock synchronization with the other nodes; and finishing the interface setting of the cluster, calling a deployment interface of a background to finish the deployment of the cluster, installing distributed storage management software, and finally finishing the establishment of the cluster and the generation of basic resources.
In step S101, after receiving the storage request, it may be determined whether the storage request includes an authorization code of the storage cluster; if so, the initialization of the storage cluster is executed through the storage request; otherwise, the storage request is rejected. An authorization code needs to be provided or the clustering is performed on a trial basis when logging into the storage cluster. The storage cluster is initialized first, that is, block scene initialization, file scene initialization, and object scene initialization are performed according to a pre-configured wizard configuration file. If the initialization fails when the block scene initialization, the file scene initialization and the object scene initialization are executed according to the pre-configured wizard configuration file, the initialization process that the initialization fails can be rolled back by using the rollback configuration file. Such as cluster _ guide _ san ═ 0, cluster _ guide _ nas ═ 0, and cluster _ guide _ obj ═ 0, as flags for whether each scene has completed initialization. And initializing a corresponding scene according to the service requirement, and if not all the scenes are initialized, initializing additional scenes if necessary subsequently. In the process of initializing a scene, if a situation of initialization failure is encountered, setting a corresponding configuration parameter of a rollback configuration file to be 1, indicating that the scene initialization fails and rollback needs to be performed. And after the problems are eliminated, continuously finishing the initialization of the scene.
In the object initialization process, firstly, multi-site setting is needed for an object scene, the cluster is generally set as a master site, if a multi-site environment is to be built, the cluster is used as a slave site, configuration is needed on the premise that the building of the master site is completed, a synchronous endpoint address of the master site needs to be set, a port number defaults 7009, and a public key and a private key of a user are defaulted by the master site. If the metadata retrieval configuration is started, the metadata site name, the index fragment number and the index copy number need to be set, and the function of metadata retrieval is provided. And the object metadata pool adopts a copy strategy for storing the metadata of the object, and if the metadata is not set, the metadata pool and the data pool are shared. The object data pool may be configured as an erasure correction and copy type storage pool, and the storage pool information is additionally configured in a guide. conf file, and the cluster _ guide _ pools _ obj ═ object _ pool. RGW (rados gateway) is a service of object storage, which can enable a client to access a storage cluster by using a standard object storage API, support APIs of S3 and Swift, and simultaneously open RGW services of each node of the cluster, namely, system start icfs-radosgw @ radosgw.
In the file initialization process, the MDS service process of each node in the cluster needs to be started, each node comprises 2 nodes which are used as a master and a slave, and the master service process is activated by default. The configuration of the file metadata pool and the configuration of the data pool are used for storing metadata and data use of the file, and the storage pool information is additionally configured into a guide. The CIFS is a file system for realizing file sharing service, is mainly used for file sharing, needs to provide service under the condition that smb service is started, and starts smb service through systemctl start smb; nfs (network File system) is a local network File system, which can be accessed through the standard protocol of the internet, and can open the service through the systemctl start gateway.
In the block initialization process, a block data pool is configured first, the creation of a general pool HDD and a high-level pool SSD is supported, and the configuration may be set to an erasure type or a copy type, which is used for performing data storage of a block storage service, and storage pool information is additionally configured in a guide. The block storage needs to configure the tgtd service, and the ansible tool is used to start the tgtd service, system start tgtd, of each node in the cluster. On the basis of tgtd service, a block access interface can be provided for external use, and is used for butt joint of rbd or iscsi, and the like, so that block resources of the cluster are accessed.
According to the embodiment of the application, the file, the object and the block service are expanded in the same cluster as required, a standard protocol interface is provided for upper-layer application to use, unified storage pool management is provided, and the attribution of bottom-layer resources is dynamically adjusted according to the service data requirement. The complexity of management and the maintenance cost are well reduced.
