Description
Technical Field
The present invention relates to the field of data storage technologies, and in particular, to a method, an apparatus, a device, and a computer readable storage medium for calling a dual active volume.
Background
The cloud computing operating system (OpenStack) manages computing, storage, and network resources of one data center. Due to the strong expansibility and usability of OpenStack, more and more enterprises and organizations currently build private clouds by using OpenStack, establish cloud hosts and deploy services of the cloud hosts. As the business scale expands, the enterprise needs to store a large amount of data, so the enterprise purchases business storage and accesses the storage to the OpenStack cloud platform, creates a data volume in the storage through the OpenStack, and mounts the data volume to the cloud host for use. Meanwhile, for data security, more and more enterprises use stored dual live volumes to store data. The dual-active volume must be provided by dual-active storage, which means that two storage devices form a dual-active relationship, and once one storage device is down, the other storage device automatically takes over, so that the service of the virtual machine in the cloud platform is not affected.
To meet different usage scenarios, volumes mounted to cloud hosts may include multiple types, such as dual live volumes, normal volumes, thin volumes, and so on. To distinguish between different volumes, the storage controller may assign a volume number (scsi_id) to each volume. The scsi_ids corresponding to different types of volumes in the same IO group are set in an incremental manner. A dual live volume occupies two IO groups, which can cause the scsi_id of the dual live volume in different IO groups to be inconsistent when multiple types of volumes exist. When the Cinder driver acquires the sci_id, only one sci_id is acquired, and meanwhile, the cloud platform os-brick module only uses one sci_id to discover devices when performing a disk scanning operation, so that a disk scanning error can occur when the cloud platform uses the sci_id to scan a disk, and the wrong path device is used, and further, the wrong volume in the storage device is used.
It can be seen that how to ensure the proper use of dual live rolls when multiple types of rolls are present is a problem that one skilled in the art would need to solve.

Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The terms "comprising" and "having" and any variations thereof in the description and claims of the present application and in the foregoing drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
Next, a method for calling a dual live volume provided in the embodiment of the present application will be described in detail. Fig. 1 is a flowchart of a method for calling a dual active volume according to an embodiment of the present application, where the method includes:
s101: and connecting the dual-active volume storage clusters to obtain the volume numbers of the dual-active volumes corresponding to the IO groups.
The storage end of the cloud computing operating system cannot directly acquire the volume numbers of the dual-active volumes, so that the volume numbers of the dual-active volumes corresponding to the IO group are acquired in a manner of connecting the dual-active volume storage clusters.
In a specific implementation, the storage end may call an initialization_connection function to obtain a host name and host identification information of a cloud host where the virtual machine is located.
In practical applications, iqn (iSCSI qualified name ) information of the host may be used as host identification information, where the host identification information may be used to distinguish different cloud hosts.
In order to realize the mounting of the dual live volumes, virtual host resources are required to be created according to the host names; binding the host identification information with the virtual host resource; thereby mapping the dual live volume to be mounted to the virtual host resource.
In a specific implementation, a Command Line Interface (CLI) Command may be invoked to bind host identification information with a virtual host resource, and the CLI Command may be invoked to map a dual live volume to be mounted to the virtual host resource.
After mapping the dual-active volume to the virtual host resource, the system automatically allocates the volume number for the dual-active volume, but the storage end cannot directly obtain the volume number of the dual-active volume, so that the storage end needs to obtain the volume number corresponding to the dual-active volume according to the mapping relationship between the dual-active volume and the virtual host resource.
In a specific implementation, the storage end may call the CLI command to obtain a mapping relationship between the dual active volume and the virtual host resource, and parse a volume number (scsi_id) corresponding to the dual active volume from the mapping relationship. The number of scsi_ids of the obtained dual live volumes is plural. The sci_ids corresponding to different IO groups (IO_grp) are not consistent, so that the corresponding relation between the IO_grp and the sci_id needs to be obtained and stored in the map for subsequent use.
S102: and obtaining the controller node information of each IO group.
In the embodiment of the application, in order to facilitate the cloud host to clearly acquire the corresponding relation between the IO group and the dual active volume number, the controller node information may be used to represent different IO groups.
One dual live volume corresponds to two controller nodes, each of which can be considered an IO group. In practical application, the node identity (target_ iqn) and the node port identity (target_portal) of the controller node can be used as the controller node information, and the combination mode of the node identity and the node port identity can be used for distinguishing different controller nodes.
S103: and establishing a corresponding relation between the controller node information and the volume number of the dual-active volume so as to facilitate the cloud host to call the dual-active volume according to the corresponding relation.
When the corresponding relation between the controller node information and the volume number of the dual-active volume is established, the corresponding relation between the volume number corresponding to the dual-active volume and the node identity and the node port identity can be established according to the IO group to which the controller node belongs and the IO group to which the dual-active volume belongs.
By feeding back the corresponding relation between the controller node information and the volume numbers of the dual active volumes to the cloud host, the cloud host logs in each link through ischiadm in sequence and scans the disk according to the corresponding relation, and even if the scsid of the storage end volume is multiple, the cloud host can ensure that the host side scans correct equipment information.
In the embodiment of the application, openStack includes two parts, which are respectively components Cinder for managing the block storage device; the component Os-bridge used to discover storage devices at the cloud host.
In practical application, to ensure that the cloud host can realize correct disk scanning, the Cinder driver and the os-bridge module are optimized.
Optimization for the Cinder driver includes modifying the initialization_connection function so that dual active storage clusters can be connected through SSH to obtain the corresponding scsi_id of dual active volumes in all IO groups. And binding the target_ iqn, target_portal and scsi_id, and returning the bound result to the cloud host of the OpenStack.
The optimization for the os-bridge module comprises obtaining the information returned by the Cinder driver to obtain the corresponding relationship of target_ iqn, target_portal and scsi_id. And logging in each link through ischiadm in turn according to the corresponding relation and sweeping the disc. Even if there are multiple scsi_ids of the storage volume, the host side can be guaranteed to scan out the correct device information.
In the embodiment of the application, through optimizing the function of the Cinder drive and the os-bridge module in the OpenStack, when the OpenStack mounts the volume, the OpenStack can mount both the dual live volume and the common volume, and the use scene of a user is expanded. For uncore data, the common volume is mounted for storage, so that the utilization rate of storage resources is improved.
According to the technical scheme, the dual-active volume storage clusters are connected to obtain the volume numbers of the dual-active volumes corresponding to the IO groups; obtaining controller node information of each IO group; the controller node information is used to indicate disk locations of dual live volumes on the storage device. In order to ensure that the cloud host can realize correct disk scanning even if the volume numbers of the dual-active volumes in different IO groups are inconsistent, the corresponding relation between the controller node information and the volume numbers of the dual-active volumes can be established, so that the cloud host can conveniently realize the call of the dual-active volumes according to the corresponding relation. In the technical scheme, the volume numbers of the dual-active volumes and the controller node information of each IO group can be acquired from the storage end, the cloud host can be ensured to realize correct disk scanning depending on the volume numbers of the dual-active volumes by binding the dual-active volumes with the corresponding controller nodes, the virtual machine is supported to mount both the common volumes and the dual-active volumes, and the use scene of a user is expanded.
In the embodiment of the application, the volume number, the node identity and the node port identity of the dual-active volume with the corresponding relation can be called as triple information.
When the cloud platform uses multiple paths, the corresponding relation fed back by the storage end to the cloud host contains multiple triple information, and each path has corresponding triple information.
In a specific implementation, the cloud host can initiate a login request according to the corresponding relation between the volume number corresponding to the dual-active volume, the node identity and the node port identity; each login request has a corresponding equipment path; until all links are logged in, multiple device paths, such as/dev/sdb,/dev/sdc, etc., may appear in the cloud computing operating system. The cloud host may acquire a volume id corresponding to each device path, and aggregate device paths with the same volume id into one multipath device.
In the embodiment of the application, the cloud host aggregates a plurality of device paths corresponding to the same volume into one multi-path device, so that other devices such as a virtual machine can conveniently access the multi-path device.
