Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the prior art, in order to meet the demand of clients on cluster expansion, the cluster expansion is mainly realized in a manual expansion mode at present, a new host computer is manually added, a data communication network and a storage communication network are configured, a VS (virtual switch) or a VS is established, and the manual intervention mode is not only inflexible, but also seriously wastes a large amount of manpower and material resources.
Therefore, the embodiment of the application discloses a cluster capacity expansion method, which avoids the manual capacity expansion process and saves a large amount of human resources.
Referring to fig. 1 and fig. 2, a flow chart of a cluster expansion method disclosed in an embodiment of the present application, as shown in fig. 1 and fig. 2, includes:
S101: adding the newly added host into a current cluster, and deploying network configuration in the current cluster;
In a specific implementation, when the cluster expands, a newly added host is added to the cluster of the secure resource pool, and a network configuration of the current cluster is deployed, wherein the cluster is a group of computers, and provides a group of network resource services for users as a whole, and the network configuration comprises a data communication network and a storage communication network, so that the newly added host can perform network communication with the current cluster.
S102: acquiring the number of original hosts in the current cluster;
in this step, the original host number before capacity expansion in the current cluster is obtained.
S103: and creating or expanding the virtual storage of the current cluster based on the original host number.
In this embodiment, a corresponding capacity expansion algorithm is selected based on the number of original hosts, so that host capacity expansion is implemented according to the capacity expansion algorithm. If the current cluster has VS, directly expanding the VS; if the current cluster does not create the VS, creating the corresponding VS according to the capacity expansion algorithm. For example, if the original host number is 1, virtual storage needs to be created and expanded; if the original host number is 2, the original host number is greater than 1, which indicates that the cluster and the corresponding virtual storage already exist, so that when the cluster is expanded under the condition that the original host number is greater than 1, the virtual storage of the current cluster can be directly expanded.
According to the scheme, the cluster capacity expansion method provided by the application comprises the following steps: adding the newly added host into a current cluster, and deploying network configuration in the current cluster; acquiring the number of original hosts in the current cluster; and creating or expanding the virtual storage of the current cluster based on the original host number. According to the application, when the capacity is expanded, the virtual storage of the current cluster is created or expanded in a self-adaptive manner according to the number of the original hosts in the current cluster, so that the manual intervention process is avoided, the capacity expansion efficiency is improved, and a large amount of human resources are saved.
The embodiment of the application discloses another cluster expansion method, and compared with the previous embodiment, the embodiment further describes a cluster expansion process when the number of the original hosts is one. Specific:
referring to fig. 3, a flowchart of another cluster expansion method provided by an embodiment of the present application, as shown in fig. 3, includes:
S201: adding the newly added host into a current cluster, and deploying network configuration in the current cluster;
S202: when the number of the original hosts is one, detecting whether the newly-added host and the original hosts in the current cluster contain empty data disks or not;
S203: if the newly added host and the original host both contain empty data disks, determining the first empty data disk in the newly added host and the second empty data disk in the original host as target data disks;
S204: judging whether the virtual storage exists in the current cluster or not;
S205: if the virtual storage exists in the current cluster, adding the target data disk to the virtual storage;
S206: and if the virtual storage does not exist in the current cluster, creating the virtual storage by using the target data disk.
In this embodiment, when the number of the original hosts is one, it is detected whether a pair of empty data disks exists between the original host and the newly added host to be expanded, if so, after judging whether virtual storage exists, it is directly created or expanded by using the empty data disks.
It should be noted that, if a plurality of empty data disks are detected in the process of detecting whether the original host and the newly added host have empty data disks, any data disk may be selected as a target data disk for creating or expanding the virtual storage.
Based on the above embodiment, the embodiment of the application discloses another cluster expansion method. Specific:
referring to fig. 4, a flowchart of still another cluster expansion method provided by an embodiment of the present application, as shown in fig. 4, includes:
s301: adding the newly added host into a current cluster, and deploying network configuration in the current cluster;
s302: when the number of the original hosts is one, detecting whether the newly-added host and the original hosts in the current cluster contain empty data disks or not;
S303: if the newly added host and the original host both contain empty data disks, taking the empty data disks of the newly added host and the empty data disks of the original host as target data disks;
S304: if the empty data disk is not detected in the original host, acquiring a third data disk with the minimum disk utilization rate in the original host;
s305: acquiring all components in the third data disk, and performing migration operation on all the components;
s306: after the migration operation is completed, determining the third data disk and the first data disk as the target data disk;
S307: judging whether the virtual storage exists in the current cluster or not;
s308: if the virtual storage exists in the current cluster, adding the target data disk to the virtual storage;
s309: and if the virtual storage does not exist in the current cluster, creating the virtual storage by using the target data disk.
After detecting whether the newly added host and the original host contain empty data disks or not, if the original host does not detect the empty data disks, the embodiment obtains a third data disk with the minimum disk usage rate in the original host, namely, a data disk with the minimum capacity occupation, migrates all components in the searched third data disk, and after migration is completed, extends or creates virtual storage by taking the third data disk and the first data disk with the empty data disk in the newly added host as target data disks.
Further, as shown in fig. 5, based on the above embodiment, if the current local storage in step S304 fails to obtain, the embodiment may further obtain the solid state disk in the original host, and use the solid state disk and the first data disk that is empty in the newly added host as the target data disk to create or extend the VS. The virtual storage is also divided into a data disk and a cache disk, and a mechanical hard disk is generally used as the data disk, and an SSD (solid state disk) is used as the cache disk, but when virtual storage is not available in the early stage, the SSD disk may be initialized and stored in a local manner.
In addition, after the component is migrated and after whether virtual storage exists is detected, whether the operation is completed or whether the detection is successful is further determined, if the operation fails or the detection fails, corresponding exception processing is performed, for example, corresponding detailed error information can be printed, and the error information is returned to the foreground interface for display.
On the basis of the foregoing embodiments, this embodiment is further described with respect to the component migration process. Specific:
Referring to fig. 6 and fig. 7, a flow chart of a component migration process in a cluster expansion method according to an embodiment of the present application, as shown in fig. 6 and fig. 7, includes:
s401: judging whether the virtual storage exists in the current cluster or not;
S402: if the virtual storage exists in the current cluster, migrating all the components to the virtual storage;
S403: and if the virtual storage does not exist in the current cluster, determining a fourth data disk from the original host, and migrating all components from the third data disk to the fourth data disk.
In this embodiment, when components are migrated, whether a current cluster has a VS is determined, and if yes, all components are migrated to the VS; if not, determining a fourth data disk from the original host, and migrating all components from the third data disk to the fourth data disk.
It should be noted that, in this embodiment, the specific process of determining the fourth data disk includes: and acquiring all local storage except the third data disk in the data disk of the original host, determining the data disk with the minimum disk use rate in all the local storage, and determining the data disk as a fourth data disk.
It can be understood that the above component migration process can ensure the idempotency of migration, migrate components to VS as much as possible, and effectively save migration times and migration time.
The embodiment of the application discloses a cluster expansion method, and in comparison with the previous embodiment, the embodiment specifically further describes a cluster expansion process when the number of original hosts is multiple. Specific:
Referring to fig. 8, a flowchart of still another cluster expansion method provided by an embodiment of the present application, as shown in fig. 8, includes:
s501: adding the newly added host into a current cluster, and deploying network configuration in the current cluster;
S502: when the number of the original hosts is multiple, detecting whether a cloud security service platform is positioned in the virtual storage;
s503: if the cloud security service platform is located in the virtual storage, migrating the cloud security service platform from the virtual storage to a fifth data disk, and executing preset operation after migration;
S504: and if the cloud security service platform is not located in the virtual storage, directly executing the preset operation.
It should be noted that, the cloud security service platform is an independently developed platform for providing service security delivery in a cloud security scene. Additionally, there are currently some limitations due to the underlying mechanisms of the super fusion all-in-one machine, such as: when expanding, all disks need to be added into VS,2 hosts expand 3 hosts, and because of the arbitration mechanism of VS in HCI, all virtual devices on VS need to be shut down, so that the disks can be successfully added into the VS.
As can be seen from the above, in this embodiment, before migrating the cloud security service platform from the virtual storage to the fifth data disk, whether the cloud security service platform is located in the virtual storage is detected first, if yes, the cloud security service platform is migrated from the virtual storage to the fifth data disk, and after migration, a preset operation is executed; if not, the step of migrating the cloud security service platform from the virtual storage to the fifth data disk is skipped, and the preset operation is directly executed.
It should be noted that the above-mentioned preset operation may specifically include: and controlling all virtual machines in the virtual storage to shut down, adding all empty idle data disks of the newly added host to the virtual storage, and after the addition is completed, migrating the cloud security service platform back to the virtual storage with the idle data disks added, so as to control all virtual machines to start up, and completing the expansion of the cluster.
The embodiment of the application discloses a cluster capacity expansion method, and compared with the previous embodiment, the embodiment further describes the migration process of a cloud security service platform. Specific:
referring to fig. 9 and fig. 10, a flowchart of a cluster expansion method according to an embodiment of the present application, as shown in fig. 9, includes:
s601: adding the newly added host into a current cluster, and deploying network configuration in the current cluster;
s602: when the number of the original hosts is multiple, detecting whether a cloud security service platform is positioned in the virtual storage;
S603: if the cloud security service platform is located in the virtual storage, acquiring a fifth data disk with disk capacity larger than a preset capacity threshold value in the original host;
S604: migrating the cloud security service platform from the virtual storage to the fifth data disk;
s605: controlling all virtual machines in the virtual storage to be powered off, and adding all empty idle data disks of a newly-added host to the virtual storage;
s606: and migrating the cloud security service platform to the virtual storage, and controlling all virtual machines to start.
In this embodiment, when the cloud security service platform is migrated, a fifth data disk with a disk capacity greater than a preset capacity threshold in the original host is obtained, and the cloud security service platform is migrated from the virtual storage to the fifth data disk. Specifically, the process of acquiring the fifth data disk in the original host may include: and judging whether the system disk capacity of the original host is larger than a preset capacity threshold, and performing migration only when the system disk capacity is enough. For example, if the actual occupied disk size of the current cloud security service platform is 15G, but the system disk only has 10G of residual capacity, migration cannot be performed, if the residual capacity of only 15G cannot be performed, it is necessary to ensure that the residual capacity is greater than a preset capacity threshold, the preset capacity threshold is the sum of the actual size of the cloud security service platform and a preset constant, and the preset constant is generally defined as 5G, that is, for the cloud security service platform actually occupying 15G of disk size, the migration of the platform can be realized only when the system disk needs to satisfy the residual capacity greater than 20G. After judging whether the system disk capacity of the original host is larger than a preset capacity threshold, determining whether to migrate the cloud security service platform to the system disk according to a judging result. If the system disk capacity of the original host is not greater than the preset capacity threshold, detecting local storage except the system disk in the newly-added host, and migrating the cloud security service platform to the local storage. When the system disk capacity of the original host is not greater than a preset capacity threshold and the newly-added host does not contain local storage except the system disk, the embodiment further detects whether the newly-added host contains a solid state disk SSD, if so, the cloud security service platform is migrated to the initialized solid state disk after the solid state disk is initialized.
In addition, after the cloud security service platform is migrated from the virtual storage to the preset disk, the embodiment may further include: and formatting the residual data disk of the newly added host computer, and adding the formatted disk as a buffer disk into the virtual storage.
