In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

For ease of understanding, the terms involved in the embodiments of the present application are first explained below.

The embodiment of the present application provides a cloud disk management method for a cloud host. The cloud disk management method of the cloud host is applied to a cloud management platform. The cloud management platform receives the cloud disk association request that carries the cloud disk identifier and the cloud host identifier entered by the tenant, and the cloud management platform receives the cloud disk configuration request input by the tenant, sets the disk configuration information in the cloud disk according to the cloud disk configuration request, and then , the cloud management platform determines the cloud disk and the cloud host according to the cloud disk association request, and sets the cloud disk on the cloud host. The cloud disk identifier is used to identify the tenant's cloud disk, and the cloud host identifier is used to identify the tenant's cloud host. The disk configuration information is used to instruct the cloud host to configure the cloud disk.

FIG. 1 is a schematic diagram of an implementation scenario involved in a cloud disk management method for a cloud host provided by an embodiment of the present application. As shown in FIG. 1 , the implementation scenario includes: a cloud management platform 11 , a cloud host 12 and a cloud disk 13 deployed in the cloud platform 1 . A large number of basic resources owned by the cloud service provider are deployed in the cloud platform 1, and the cloud platform 1 can use the basic resources to provide cloud services to tenants. The basic resources may include computing resources, storage resources, network resources, etc., and the computing resources may be a large number of computing devices (eg, servers).

The cloud management platform 11 , the cloud host 12 and the cloud disk 13 can be implemented according to the basic resources in the cloud platform 1 . In an implementation manner, the cloud management platform 11 may be implemented by software deployed on computing resources, where the software is used to implement the cloud disk management method of the cloud host provided by the embodiment of the present application. Optionally, the cloud host 12 may be a virtual machine or container simulated by software on the basic resource, or the basic resource includes a bare metal server, and the cloud host 12 may be a bare metal server in the cloud platform 1 . The cloud host 12 is used to implement the tenant's business and provide the tenant with cloud services. The tenant's services include software application services created by the cloud platform 1 according to the user's service requirements, such as language recognition services, video review services, or image rendering services. The cloud disk 13 may be a disk simulated by software using basic resources, and the cloud disk 13 has basically the same function as a physical disk.

Optionally, the cloud disk 13 may be a cloud disk purchased together with the cloud host 12 , and in this case, the cloud disk 13 may be called a newly added cloud disk. In this case, after the tenant purchases, the cloud disk that has been mounted on the cloud host 12 can be obtained. At this time, before the cloud host 12 uses the cloud disk 13 , it is necessary to connect the cloud disk 13 with the cloud host 12 , initialize the configuration of the cloud disk 13 , and the like. Initializing and configuring the cloud disk 13 includes creating a partition for the cloud disk 13 , initializing the file system of the cloud disk 13 , and assigning a drive letter to the cloud disk 13 . The mounting refers to configuring the cloud disk 13 as a component of the cloud host 12 , so that the cloud host 12 can identify the cloud disk 13 , so that the cloud host 12 can operate the cloud disk 13 . The connection between the cloud disk 13 and the cloud host 12 refers to establishing a communication connection between the cloud disk 13 and the cloud host 12 , so that the cloud disk 13 and the cloud host 12 can exchange information.

Alternatively, the cloud disk 13 may be a cloud disk purchased by the tenant separately, and in this case, the cloud disk 13 may also be referred to as a newly added cloud disk. At this time, before the cloud host 12 uses the cloud disk 13, it is necessary to mount the cloud disk 13 on the cloud host 12, connect the cloud disk 13, create a partition for the cloud disk 13, initialize the file system and Assign configuration such as drive letter to cloud disk 13.

Alternatively, the cloud disk 13 may be a cloud disk that expands the original cloud disk of the cloud host. In this case, the cloud disk 13 may also be called a capacity-expanding cloud disk. At this time, before the cloud host 12 uses the cloud disk 13, it is necessary to perform a capacity expansion operation on the original cloud disk of the cloud host 12 according to the capacity expansion data disk, that is, add the capacity of the expanded data disk to the original cloud disk of the cloud host 12. in the file system of the disk.

Moreover, when the cloud disk 13 is a newly added cloud disk purchased together with the cloud host 12, or is a newly added cloud disk purchased by the tenant alone, according to the data volume source of the cloud disk 13, the newly added cloud disk can also be classified into: two kinds. That is, when the source of the newly added data volume is a blank volume, the newly added cloud disk is a blank cloud disk, that is, there is no data in the newly added cloud disk. At this time, the newly added cloud disk can be called no data. , or a blank new cloud disk. When the data volume of the newly added cloud disk is created from a data volume with data such as a mirror image, backup, or snapshot of the data disk, the new cloud disk obtained by creating the volume can be called a newly added cloud disk with data. In addition, if the capacity of the data volume on which the volume is created is equal to the capacity of the new cloud disk obtained by creating the volume, the new cloud disk obtained by creating the volume can also be called a new cloud disk without capacity expansion. When the capacity of the data volume is smaller than the capacity of the new cloud disk obtained by creating the volume, the new cloud disk obtained by creating the volume can also be called a new cloud disk with capacity expansion.

With the cloud disk management method of the cloud host provided by the embodiment of the present application, the cloud disk can be automatically set on the cloud host, so that after purchasing the cloud disk, the tenant can directly use the cloud disk without the need for the tenant to manually configure the cloud disk The purchased cloud disk improves the tenant experience.

The following describes an implementation process of a cloud disk management method for a cloud host provided by an embodiment of the present application. As shown in Figure 2, the implementation process of the cloud disk management method of the cloud host may include the following steps:

Step 201: The cloud management platform receives a cloud disk creation request input by the tenant, and creates a cloud disk according to the cloud disk creation request, wherein the cloud disk is set with a cloud disk identifier.

When a tenant needs to configure a cloud disk for the cloud host purchased by the tenant, the tenant can send a cloud disk creation request to the cloud management platform to request the cloud management platform to create a cloud disk according to the cloud disk creation request, so as to facilitate the cloud host purchased from the tenant. Configure cloud disks. Moreover, the cloud disk has a cloud disk identifier, and the cloud disk identifier is used to uniquely identify the cloud disk. Correspondingly, the cloud disk creation request may carry the cloud disk identifier of the cloud disk to request the cloud management platform to create the cloud disk with the cloud disk identifier. After the tenant sends a cloud disk creation request, the cloud management platform can receive the cloud disk creation request input by the tenant, and create a cloud disk according to the cloud disk creation request.

Optionally, the cloud disk requested to be created by the cloud disk creation request may be a cloud disk purchased with the cloud host, or may be a cloud disk purchased by the tenant separately, or may be an original cloud disk of the cloud host. The expanded cloud disk, and the source of the data volume on which the cloud disk is created can be selected according to application requirements, which are not specifically limited in this embodiment of the present application.

In an implementation manner, the cloud disk creation request may be triggered by an operation of the tenant purchasing a cloud disk on the management interface of the cloud management platform. For example, the cloud disk creation request may be triggered by the operation of the tenant entering purchase parameters on the purchase interface for purchasing the cloud disk on the cloud management platform, where the purchase parameter is used to reflect the tenant's demand for the cloud disk.

In addition, in order to ensure that tenants can purchase cloud disks on demand, the cloud management platform can provide one or more of the following purchase parameters for the purchase of cloud disks: the billing model of the cloud disk, the deployment region of the basic resources used to create the cloud disk, and where the basic resources are located. The specific availability zone in the deployment region, the performance specifications of the cloud disk, the size (capacity) of the cloud disk, the cloud backup function of the cloud disk, the cloud disk identifier of the cloud disk, the purchase time and quantity of the cloud disk. The billing mode of the cloud disk is used to indicate the billing method of the cloud disk, which may include annual/monthly and on-demand billing. The deployment region of the basic resources used to create the cloud disk is used to indicate the geographic location of the physical machine on which the cloud disk is created. The specific availability zone of the basic resource in the deployment region is used to indicate the availability zone of the physical machine on which the cloud disk is created. The performance specifications of the cloud disk are used to indicate the performance indicators of the cloud disk, such as the maximum number of read and write operations per second (input/output operations per second, IOPS), the maximum throughput, and the read and write latency of the cloud disk. and other performance.

For example, FIG. 3 is a schematic diagram of a purchase interface for purchasing a cloud disk on a cloud management platform according to an embodiment of the present application. As shown in Figure 3, tenants can select the billing method for cloud disks as annual/monthly or on-demand billing in the billing mode selection box, and tenants can select the basis for creating cloud disks in the region selection box. The deployment region of the resources is in any of South China, North China, East China, or Southwest China. Tenants can select the specific availability zone of the basic resource in the deployment region in the selection box of the availability zone. Unavailable Zone 1, Availability Zone 2, Available In Zone 3 or Availability Zone 7, tenants can select the performance specifications of cloud disks that meet the ultra-high IO performance specifications, general-purpose SSD performance specifications, high IO performance specifications, or common IO performance specifications in the disk specification selection box. You can select the size (capacity) of the cloud disk in the selection box of the disk size. Tenants can choose whether to configure the cloud backup function for the cloud disk in the selection box of cloud backup. The tenant can fill in the cloud disk to be purchased in the box of the disk name. The cloud disk identifier of the disk. If the cloud disk identifier is filled in as "volume e-e672", the tenant can select the purchase duration of the cloud disk in the selection box of the purchase duration, and the tenant can select the cloud disk to be created in the selection box of the purchase amount total. In addition, as shown in Figure 3, the cloud management platform is also configured with more options, so that tenants can choose some other settings of the cloud disk, such as choosing whether to set it as a shared disk, selecting the interface between the cloud disk and the cloud host Whether it is a small computer system interface (SCSI), select whether the cloud disk is an encrypted disk or whether to add a label to the cloud disk, etc.

It should be noted that FIG. 3 is only an example of a purchase interface, and setting items therein may be added, deleted, or changed according to application requirements, which are not specifically limited in this embodiment of the present application.

Step 202: The cloud management platform receives a cloud disk association request input by the tenant and carrying the cloud disk identifier and the cloud host identifier.

After purchasing a cloud disk, a tenant can instruct to mount the purchased cloud disk to a cloud host. The instruction to mount the purchased cloud disk to the cloud host will trigger a cloud disk association request. That is, the cloud disk association request is used to request that the cloud disk involved in the cloud disk association request be mounted to the cloud host involved in the cloud disk association request for use. In addition, since cloud disks can be identified by cloud disk identifiers, and cloud hosts can be identified by cloud host identifiers, the tenant's instruction operation also includes entering the cloud disk identifiers of the cloud disks to be associated with and the cloud host identifiers of the cloud hosts. , correspondingly, the cloud disk association request carries the cloud disk identifier and the cloud host identifier. After the tenant inputs the cloud disk association request carrying the cloud disk identifier and the cloud host identifier, the cloud management platform can receive the cloud disk association request.

Optionally, when mounting a cloud disk to a cloud host, from the perspective of a cloud disk, first select a cloud disk, then select the mounting function of the cloud disk, and then select the cloud disk under the mounting function of the cloud disk. The cloud disk needs to be mounted on the cloud host. Alternatively, from the perspective of the cloud host, first select the cloud host, then select the mount function of the cloud host, and then change the mount function of the cloud host to select the cloud disk that needs to be mounted to the cloud host.

For example, FIG. 4 is a schematic diagram of a management interface of a cloud management platform provided by an embodiment of the present application. When the cloud disk needs to be mounted to the cloud host, the tenant can first select the cloud disk to be mounted. As shown in Figure 4, the cloud disk identified as "sluo-ecs-9138-volume-001" is selected. After the tenant selects the mount function of the cloud disk, the tenant's terminal will display the disk mount interface of the cloud disk shown in Figure 4, and then the tenant can select the disk to be mounted on the mount disk interface shown in Figure 4. Cloud hosting. 4 shows that the list of optional cloud hosts includes a list of elastic cloud servers and a list of bare metal servers, and the list of bare metal servers includes cloud host identifiers "sluo-ecs-001", "zrm-kylin- 001", "zrm-neo-001", "zrm-uos-001", etc., and Figure 4 also shows the options, status, image file name, private Internet protocol of the optional mount point of each cloud host (Internet protocol, IP) address, elastic public IP address, and the availability zone to which the physical machine on which the cloud host is based belongs, the tenant can select the cloud host to which the cloud disk needs to be mounted based on the above information. In addition, after the tenant completes the selection of the cloud host to which the cloud disk needs to be mounted, he or she can click "OK" in the mount disk interface. Clicking "OK" will trigger a cloud disk association request, and the cloud disk will be associated with the cloud disk. The request carries the cloud disk ID "sluo-ecs-9138-volume-001" and the cloud host ID of the cloud host selected by the tenant.

For example, FIG. 5 is a schematic diagram of a management interface of another cloud management platform provided by an embodiment of the present application. When the cloud disk needs to be mounted to the cloud host, the tenant can first select the cloud host that is required. As shown in Figure 5, the cloud host with the cloud host ID "sluo-ecs-6075" is selected. After the tenant selects the mount function of the cloud host, the tenant's terminal will display the disk mount interface of the cloud host shown in Figure 5, and then the tenant can select the disk to be mounted on the mount disk interface shown in Figure 5. The cloud disk of the cloud host. Wherein, the list of optional cloud disks is shown in FIG. 5 , the list includes the cloud disk identification as “sluo-ecs-9138-volume-001”, and the “view cloud disk list” is also shown in FIG. 5 button, in addition, a search box S is also shown in FIG. 5 , and the cloud disk identifier of the cloud disk that needs to be mounted to the cloud host can be input in the search box S, so as to realize the search for the cloud disk that needs to be mounted to the cloud host. Choice of cloud disks. In addition, FIG. 5 also shows the cloud disk identifier, capacity, indication information of whether it is a boot disk, disk type and other related information of the cloud disk, so as to facilitate the tenant to understand the cloud disk. In addition, after the tenant completes the selection of the cloud disk to be mounted to the cloud host, he can click "OK" in the mount disk interface. Clicking "OK" will trigger a cloud disk association request, and the cloud disk will be associated with the cloud disk. The request carries the cloud host ID "sluo-ecs-6075" of the cloud host and the cloud disk ID of the cloud disk selected by the tenant.

Step 203: The cloud management platform receives the cloud disk configuration request input by the tenant, and sets the disk configuration information in the cloud disk according to the cloud disk configuration request.

The cloud disk configuration request is used to reflect the tenant's setting requirements for the cloud disk. For example, when a tenant needs to expand the capacity of a cloud host, the tenant can enter a cloud disk configuration request requesting capacity expansion to instruct the cloud management platform to expand the capacity of the cloud host. Or, when a tenant needs to add a cloud disk to a cloud host, the tenant can enter a cloud disk configuration request for adding a cloud disk to instruct the cloud management platform to add a cloud disk to the cloud host. Or, when a tenant needs to add a blank new cloud disk to a cloud host, the tenant can enter a cloud disk configuration request for adding a blank new cloud disk to the cloud host to instruct the cloud management platform to add a blank new cloud disk to the cloud host. cloud disk. Or, when a tenant needs to add a new cloud disk with data to a cloud host, the tenant can enter a cloud disk configuration request for adding a new cloud disk with data to the cloud host to instruct the cloud management platform to add data to the cloud host. 's new cloud disk.

After the tenant triggers the cloud disk configuration request, the cloud management platform can receive the cloud disk configuration request. After the cloud management platform receives the cloud disk configuration request, it can learn the tenant's setting requirements for the cloud disk, and perform corresponding configuration operations on the cloud disk according to the setting requirements. The configuration operation of the cloud disk by the cloud management platform will change the cloud disk, and the change can be represented by the disk configuration information. That is, after receiving the cloud disk configuration request input by the tenant, the cloud management platform can set the disk configuration information in the cloud disk according to the cloud disk configuration request. When the cloud disk carries the disk configuration information, the cloud host can know what kind of cloud disk the cloud disk is when reading the cloud disk, and then perform corresponding configuration on the cloud disk.

For example, when a tenant inputs a cloud disk configuration request for expansion, the cloud management platform can set a cloud disk for expansion according to the cloud disk configuration request, and the configuration of the expanded cloud disk can be characterized by the disk configuration information, so that the cloud host is reading When the configuration information of the disk is obtained, it can be known that the cloud disk is an expanded cloud disk, and a capacity expansion operation is performed on the expanded cloud disk. In this case, the disk configuration information includes a capacity expansion identifier, and the capacity expansion identifier is used to instruct the cloud host to use the cloud disk to expand the existing disk. That is, when the cloud host reads the expansion identifier of the cloud disk, it knows that the cloud disk needs to be expanded, and then performs the expansion operation on the expanded cloud disk.

For another example, when a tenant inputs a cloud disk configuration request for adding a new cloud disk, the cloud management platform can set a new cloud disk according to the cloud disk configuration request, and the configuration of the newly added cloud disk can be characterized by the disk configuration information, so that the When the cloud host reads the configuration information of the disk, it can know that the cloud disk is a newly added cloud disk, and perform operations such as initializing the newly added cloud disk. In this case, the disk configuration information includes a newly added identifier, and the newly added identifier is used to instruct the cloud host to perform operations such as initializing and configuring the newly added cloud disk. That is, when the cloud host reads the newly added identifier of the cloud disk, it can know that the corresponding initial configuration and other operations need to be performed on the cloud disk.

For another example, when a tenant enters a cloud disk configuration request for adding a blank new cloud disk to a cloud host, the cloud management platform can create a cloud disk, format the created cloud disk, and then store the formatted cloud disk. It is set to a bare disk, and the configuration of the new blank cloud disk can be represented by the disk configuration information, so that the cloud host can know that the cloud disk is a blank new cloud disk when it reads the disk configuration information, and Perform operations such as initializing the newly added cloud disk. In this case, the disk configuration information includes a format identifier, and the format identifier is used to instruct the cloud host to format the cloud disk, and set the formatted cloud disk as a raw disk. That is, when the cloud host reads the format identifier of the cloud disk, it knows that the cloud disk needs to be formatted, and the formatted cloud disk is set as a raw disk.

For another example, when a tenant inputs a cloud disk configuration request for adding a new cloud disk with data to a cloud host, the cloud management platform can create a cloud disk based on the data volume with data, and retain the cloud disk during the process of creating the cloud disk. The data in the disk, and set the cloud disk as a new disk, and the configuration of the new cloud disk with data can be characterized by the disk configuration information, so that the cloud host can know the disk configuration information when it reads the disk configuration information. A cloud disk is a newly added cloud disk with data, and the corresponding initial configuration and other operations are performed on the newly added cloud disk with data. In this case, the disk configuration information includes a data retention identifier, and the data retention identifier is used to instruct the cloud host to retain the data in the cloud disk, and set the cloud disk as a newly added disk. That is, when the cloud host reads the data retention identifier, it can retain the data in the cloud disk while setting the cloud disk.

Further, when inputting a cloud disk configuration request, the user may also indicate a division method for dividing the cloud disk. For example, it indicates how many partitions the cloud disk is divided into and the size of each partition. At this time, the disk configuration information further includes a division indication, where the division indication is used to indicate a division manner of the cloud disk. By setting the division instruction in the cloud disk, when the cloud host reads the division instruction, it can divide the cloud disk according to the division instruction when setting the cloud disk.

It should be noted that the above description of the cloud disk configuration request and disk configuration information is only an exemplary description, and is not intended to limit the specific form of the cloud disk configuration request that the tenant can input. It is adjusted according to application requirements, which is not specifically limited in this embodiment of the present application. In addition, the disk configuration information may include one or more of the above information, which is not specifically limited in this embodiment of the present application. For example, the disk configuration information may include any one of a capacity expansion identifier, a format identifier, and a data retention identifier. Alternatively, the disk configuration information may include a capacity expansion identifier and a data retention identifier. Alternatively, the disk configuration information may include a format identifier and a data retention identifier. Alternatively, the disk configuration information may include an expansion identifier and a format identifier. Alternatively, the disk configuration information may include a capacity expansion identifier, a format identifier, and a data retention identifier.

Step 204: The cloud management platform determines the cloud disk and the cloud host according to the cloud disk association request, and sets the cloud disk on the cloud host.

After receiving the cloud disk association request, the cloud management platform can determine the cloud disk to be configured according to the cloud disk identifier carried in the cloud disk association request, and determine the cloud disk that needs to be configured according to the cloud host identifier carried in the cloud disk association request. Establish an associated cloud host, and set the cloud disk on the cloud host, that is, mount the cloud disk to the cloud host, so that the cloud host can read the disk configuration information set in the cloud disk, so that the cloud host can read the disk configuration information according to the disk. The configuration information configures the cloud disk.

Step 205: The cloud host configures the cloud disk according to the disk configuration information.

Optionally, as shown in FIG. 6 , the implementation process of this step 205 includes:

Step 2051: The cloud host modifies the online state of the cloud disk to online, and modifies the read and write permissions of the cloud disk to read and write permissions.

The connection between the cloud disk and the cloud host refers to establishing a communication connection between the cloud disk and the cloud host, so that the cloud disk and the cloud host can exchange information. That is, when the online status of the cloud disk relative to the cloud host is online, the cloud host can communicate with the cloud disk. Therefore, when setting the cloud disk, you need to change the online status of the cloud disk to online first. . In addition, when setting the cloud disk, it is necessary to write information to the cloud disk. Therefore, when setting the cloud disk, it is necessary to ensure that the read and write permissions of the cloud host to the cloud disk are at least readable. The read and write permissions are changed to read and write permissions. Optionally, changing the read and write permissions of the cloud disk to be set to read and write permissions can be implemented by erasing the read-only permissions of the cloud disk.

In addition, the process of setting the cloud disk by the cloud host may be performed on all data disks in all cloud disks of the cloud host, or may be performed on the detected cloud disks that have not been configured, which is not specifically limited in this embodiment of the present application. . The cloud disk includes a system disk and a cloud disk. The system disk is used to store data related to the operating system of the cloud host. Cloud disks are used to store non-operating system data of cloud hosts. For example, a cloud disk of a cloud host is used to store user data of the cloud host. When executed for all data disks of the cloud host, the cloud disks in steps 2051 to 2053 refer to all data disks of the cloud host, and before executing step 2051, it is also necessary to obtain the information of all cloud disks of the cloud host, And filter out all data disks according to the information of all cloud disks, and set all data disks. In an implementation manner, the information of all cloud disks of the cloud host can be obtained through the disk partition management tool in the operating system of the cloud host, and according to the logic of setting the cloud disks in the operating system of the cloud host, in the cloud host's operating system Data disks are filtered out of all cloud disks. For example, the disk partition management tool diskpart of the Windows operating system can be used to obtain the information of all cloud disks of the cloud host, and since the disk number of the system disk in the Windows system is equal to 0, that is, the cloud disks with the disk number greater than 0 are all data disks , you can set all cloud disks whose disk numbers are greater than 0.

By way of example, FIG. 7 is a schematic diagram of information of all cloud disks of a cloud host that is acquired according to an embodiment of the present application. As shown in FIG. 7 , the cloud host includes two cloud disks, and the disk numbers of the two cloud disks are respectively 0 and 1, the status (status) of the cloud disk with disk number 0 is online (online), the total capacity (size) is 40 gigabytes (GB), and the free capacity (free) is 0 bytes (B ), the status of the cloud disk with disk number 1 is offline, the total capacity is 10GB, and the available capacity is 9GB, and it can be determined that the cloud disk with disk number 1 is a data disk, and the disk number is Change the online status of cloud disk 1 to online, and change the read and write permissions of the cloud disk with disk number 1 to read and write permissions.

Step 2052: The cloud host expands the cloud disk of the cloud host.

Expanding the cloud disk of a cloud host means adding the capacity of the expanded cloud disk to the expanded cloud disk to increase the capacity of the cloud disk. Optionally, the implementation process of this step 2052 may include:

Step 2052a, the cloud host determines the logical volume to be expanded in the cloud disk and the expansion volume for expanding the logical volume.

In an implementation manner, the cloud disk to be expanded and the cloud disk used for expansion are usually logical volumes in the cloud disk, that is, the cloud disk to be expanded can be regarded as the logical volume to be expanded, which is used for the expansion of the capacity. A cloud disk whose capacity is expanded by a logical volume can be regarded as a capacity expansion volume (in fact, it is also a logical volume, but for convenience of distinction, it is referred to as a capacity expansion volume in this embodiment of the present application). In addition, the expanded logical volume and the expanded volume satisfy: the expanded logical volume and the expanded volume belong to the same cloud disk, and the storage address of the expanded logical volume is continuous with the storage address of the expanded volume. Therefore, the volume information of all logical volumes of the cloud host can be obtained, and according to the storage address of the cloud disk to which the logical volume indicated by the volume information of the logical volume belongs and the storage address of the logical volume to The expansion volume of the volume to be expanded.

In addition, the process of expanding the cloud disk by the cloud host can be performed on all logical volumes except the system volume in all cloud disks of the cloud host, and can also be performed on the detected logical volumes that have not been expanded. It is not specifically limited. In addition, when executing on all logical volumes of the cloud host except the system volume, before performing step 2052, it is also necessary to obtain the information of all logical volumes of the cloud host, and filter out all logical volumes according to the information of all logical volumes except the system volume. All logical volumes except the system volume, and perform expansion operations on all logical volumes except the system volume. In an achievable manner, the information of all logical volumes of the cloud host can be obtained through the disk partition management tool in the operating system of the cloud host, and the logical volume of the cloud host can be set according to the logic of the operating system of the cloud host. All logical volumes except system volumes are filtered out of all logical volumes. For example, the disk partition management tool diskpart of the Windows operating system can be used to obtain the information of all cloud disks of the cloud host, and since the volume number of the system volume in the Windows system is equal to 0 or 1, that is, the logical volume with the volume number greater than 1 is not system volume, you can perform expansion operations on all logical volumes with volume numbers greater than 1.

By way of example, FIG. 8 is a schematic diagram of information about all logical volumes of a cloud host that is acquired according to an embodiment of the application. As shown in FIG. 8 , the cloud host includes three logical volumes, and the volume numbers of the three logical volumes are respectively are 0, 1 and 2. The label of the logical volume with the volume number 0 is the system reserved drive letter, the file system used is the new technology file system (NTFS), the type is partition type, and the total capacity (size) is 500 megabytes Bytes (MB), the status (status) is healthy (healthy), and the information (info) identifies it as a system (system) volume. The cloud disk to which the logical volume with volume number 1 belongs is disk C, the file system used is NTFS, the type is partition type, the total capacity is 39 GB, the status is healthy, and the information identifies it as a boot volume. The cloud disk to which the logical volume with volume number 2 belongs is disk D, the file system used is NTFS, the type is partition type, the total capacity is 2014MB, and the status is healthy. Then, it can be determined that the logical volume whose volume number is 2 is not a system volume, and the expansion operation is performed on the logical volume whose volume number is 2.

Step 2052b, the cloud host adds the capacity of the expanded volume to the file system of the logical volume.

After the cloud host determines the expanded logical volume in the cloud disk and the expanded volume used to expand the logical volume, the cloud host can add the capacity of the expanded volume to the file system of the logical volume to complete the expansion operation of the logical volume. By way of example, FIG. 9 is a schematic diagram of the state of the disk 1 before the capacity expansion operation is performed, and FIG. 10 is a schematic diagram of the state of the disk 1 after the capacity expansion operation is performed. As shown in Figure 9, before the expansion operation is performed, the disk 1 includes two parts of capacity, one part is the 100GB capacity included in the newly added volume (D:), and the other part is the unallocated 50GB capacity. It can be seen from this that the unallocated 50GB capacity is the capacity of the expansion volume for expanding the newly added volume (D:), then the 50GB capacity of the expanded volume can be added to the file system of the newly added volume (D:). , in order to realize the expansion of the newly added volume (D:). As shown in Figure 10, the capacity of the newly added volume (D:) after expansion is 150GB, and its capacity is equal to the sum of the capacity of the newly added volume (D:) before expansion and the unallocated 50GB capacity. The file system used by the volume (D:) is all NTFS.

Step 2053, the cloud host formats the cloud disk.

Formatting the cloud disk of the cloud host refers to formatting the newly added cloud disk. The available capacity of the newly added cloud disk is greater than 0. In an achievable manner, information of all cloud disks of the cloud host can be obtained through a disk partition management tool in the operating system of the cloud host, and a new cloud disk can be determined according to the information of the cloud disk. For example, the disk partition management tool diskpart of the Windows operating system can be used to obtain information of all cloud disks of the cloud host, and determine the cloud disks whose available capacity is greater than 0 as indicated by the information of the cloud disks as new cloud disks. For example, please continue to refer to Figure 7, the available capacity of the cloud disk with disk number 0 is 0 bytes (B), the available capacity of the cloud disk with disk number 1 is 9 GB, and it can be determined that the cloud disk with disk number 1 has The disk is a newly added cloud disk, and the newly added cloud disk is formatted.

Optionally, when the newly added cloud disk is a blank newly added cloud disk, the cloud host can format the newly added cloud disk including: creating a partition for the newly added cloud disk, initializing the file system of the newly added cloud disk, for the new cloud disk. Increase cloud disk allocation drive letter. When the newly added cloud disk is a new cloud disk with data, since the new cloud disk with data already has file system and partition information, the cloud host can format the newly added cloud disk including: The cloud disk is assigned a drive letter. Wherein, creating a partition for the newly added cloud disk may refer to creating a primary partition for the newly added cloud disk, or creating a cloud partition and an extended partition for the newly added cloud disk. Initializing the file system of the newly added cloud disk is to specify the file system used by the newly added cloud disk. Optionally, the file system used by the newly added cloud disk may be NTFS or other file systems, which are not specifically limited in this embodiment of the present application. Allocating a drive letter to the newly added cloud disk may include: removing the drive letter already occupied by the cloud disk of the current cloud host from the alphabet, obtaining a spare drive letter table, and determining the disk of the newly added cloud disk according to the letters in the spare drive letter table. symbol. For example, when there are multiple newly added cloud disks, drive letters may be assigned to the multiple newly added cloud disks in alphabetical order in the spare drive letter table.

It should be noted that when the cloud host reads the disk configuration information in the cloud disk, the cloud host may perform some or all of the above steps 2051 to 2053 on the cloud disk, and the steps performed by the cloud host on the cloud disk may be It is determined according to application requirements, which is not specifically limited in this embodiment of the present application. For example, when the cloud host reads the disk configuration information in the cloud disk, it can perform the above steps 2051 to 2053 on the cloud disk, regardless of the specific information carried in the disk configuration information. Alternatively, when the disk configuration information includes the capacity expansion identifier, the cloud host may perform the

above steps

2051 and 2052 on the cloud disk. Alternatively, when the disk configuration information includes the format identifier, the cloud host may perform the

above steps

2051 and 2053 on the cloud disk.

In addition, the cloud host reads the disk configuration information in the cloud disk and performs some or all of the above steps 2051 to 2053 on the cloud disk. There may be various implementations. In an achievable manner, cloud management agent software may be set in the operating system of the cloud host, and the cloud management agent software may monitor and read a signal that the disk in the cloud disk in the operating system has capacity expansion or a new disk, and Part or all of the above steps 2051 to 2053 are performed on the cloud disk. In another implementation manner, the disk configuration information in the cloud disk is read, and some or all of the operations in the above steps 2051 to 2053 are performed on the cloud disk, which can be set as a startup item of the cloud host, so that in This operation is performed during the startup process of the cloud host, so that the tenant can use the set cloud disk after startup. In another implementation manner, the disk configuration information in the cloud disk is read, and some or all of the operations in the above steps 2051 to 2053 are performed on the cloud disk, which can be set as the system task plan of the cloud host operating system, so that In order to be able to perform this operation in a timely manner, the cloud disk can be configured in a timely manner.

Wherein, when implemented through the cloud management agent software and/or the system task plan, the configuration operation for the cloud disk may be performed regularly, or the configuration operation for the cloud disk may be performed when a trigger event is detected. And the trigger event may include one or more of the following: the cloud host receives a power-on instruction, the cloud host detects an event of adding a new cloud disk to the cloud host, and the cloud host detects that the original cloud disk of the cloud host is expanded. event.

In addition, when the above steps 2051 to 2053 need to be performed, if step 2052 is performed first, and then step 2053 is performed, the data in the cloud disk will not be lost due to capacity expansion, but formatting the cloud disk may cause data in the cloud disk to be lost. In the event of data loss, expanding the cloud disk first can ensure the security of the data in the cloud disk and avoid the risk of data being formatted and lost due to misoperation.
