Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the following embodiments of the present application will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present application, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present application, and the following embodiments are not described one by one.
Based on the above objective, in a first aspect of the embodiments of the present application, an embodiment of a method for mounting a virtual disk on a cloud physical machine is provided. Fig. 1 is a schematic diagram of an embodiment of a method for mounting a virtual disk on a cloud physical machine provided by the application. As shown in fig. 1, the embodiment of the present application includes the following steps:
s1, creating a virtual disk, and setting an identification of a using main body in the virtual disk;
s2, responding to a request for mounting the virtual disk, screening the virtual disk using the main body as a cloud physical machine according to the identification, and checking whether the virtual disk is available or not;
s3, responding to the availability of the virtual disk, generating a configuration file according to the address and authentication information of the virtual disk, and mounting the virtual disk to a cloud physical machine based on the configuration file; and
s4, partitioning and formatting the mounted virtual disk so that the cloud physical machine can use the virtual disk.
In a sense, the virtual machine is completely independent of hardware equipment, so that the virtual disk can be easily mounted and dismounted, but the cloud physical machine is different, and the virtual machine is also required to realize the management of logic by a virtualization technology, but basically has all resources of the current bare metal, the bare metal is in one-to-one relation, the existing virtual disk is mounted in a metadata way, the metadata of the cloud hard disk and the disk are stored together in the metadata way, and when the cloud hard disk performs a read operation or a write operation, certain throughput is occupied, because the write request of an application program can trigger the update of metadata, additional write operation is caused, and in practical application, the service flow is relatively large, and network blocking and pressure are caused to be relatively great, so that the method is inconsistent with the original purpose of using the bare metal by a user.
According to the embodiment of the application, the virtual disk interface is created, bare machine identification is added, ironic and cander modules are opened, and the cloud physical machine mounted disk interface attach_volume_ironic is newly added, so that the cloud physical machine mounts the virtual disk. An Ironic service is a collection of components that provide management and preparation of physical hardware support. The Cinder service is a component in openstack that provides block storage services, and mainly provides virtual disks for virtual machine instances.
The embodiment of the application ensures that the cloud physical machine network and the computer where the storage pool is located can be communicated when the network is constructed. When the cloud physical machine is deployed, a service network and a BMC network are arranged, and the BMC network is communicated with the control node. The cloud physical machine is required to be provided with an independent network card for mounting the virtual disk, the cloud physical machine is enabled to be enabled through an external route and an openstack management network, the networks on two sides can be enabled, and the openstack sends a request to an agent of the bare metal through a service network where the cloud physical machine is located for disk mounting operation.
The purpose of using the service network is to avoid the influence of factors such as network blocking and larger pressure as much as possible, and each group of management networks has special purposes in the actual use process and can be configured with corresponding security access rights. Compared with a service network, the service flow of the management network is smaller, the storage back end can be directly accessed through the management network, and in use, the read-write speed is higher, so that the management network is more suitable for the use of a real magnetic disk.
Creating a virtual disk, and setting an identification of a use subject in the virtual disk.
Irnoic makes a request to create and mount a virtual disk, requesting the user to create a virtual disk. And calling a client-api service, transmitting a message queue to the client-schedule after the client-api receives the request, and creating a virtual disk according to the acquired scheduling information, namely selecting an optimal node according to the environment of the system to create the virtual disk. For the extension of the original creation virtual disk interface, a default parameter is added on the basis of the original creation interface (URI format POST/v 1/volumes): { is_ironic (bol defaults to False) }. When is_ironic is False, the virtual disk is used for the virtual machine, and when is_ironic is True, the virtual disk is used for the cloud physical machine. The is_ironic Is used for distinguishing whether the virtual disk Is used for a cloud physical machine or a virtual machine, so that when the virtual disk Is mounted, the virtual disk which can be mounted can be screened directly according to the identifier, special processing such as metadata updating Is not needed, and interaction with other modules Is reduced.
After the virtual disk is created, os-bridge is called, the storage pool corresponding to the virtual disk is connected to the hypervisor, the connector information of the volume is empty at this time, and then the storage pool and the volume_id of the virtual disk are updated. The volume here is a virtual disk.
The code may be as follows:
Body:
{
volume_stor_id:volume_stor_id
Volume_id:volume_id
}
and responding to the received request for mounting the virtual disk, screening the virtual disk using the main body as the cloud physical machine according to the identification, and checking whether the virtual disk is available or not. The check-volume interface may be invoked by the ironic-api to check whether the virtual disk is available.
In some embodiments, the checking whether the virtual disk is available comprises: judging whether the sharing attribute of the virtual disk is yes or not; and in response to the shared attribute of the virtual disk not being yes, deeming the virtual disk to be unavailable. Firstly, checking whether the is_ironic shared attribute of the virtual disk is yes, if the shared attribute is no, not allowing the plurality of cloud physical machines to be mounted, and if the shared attribute is yes, allowing the plurality of cloud physical machines to be mounted.
In some embodiments, the checking whether the virtual disk is available comprises: responding to the sharing attribute of the virtual disk is yes, and judging whether a storage pool where the virtual disk exists is communicated with the IP of the cloud physical machine management network; and in response to the IP communication of the storage pool of the virtual disk and the cloud physical machine management network, recognizing that the virtual disk is available. If the virtual disk is available, calling a client-api, locking the virtual disk, preventing other users from using the virtual disk, and setting the state of the virtual disk as an attach (in-connection).
And generating a configuration file according to the address and authentication information of the virtual disk in response to the availability of the virtual disk, and mounting the virtual disk to a cloud physical machine based on the configuration file. The Ironic-conductor calls a client module to call a back-end storage pool through an os-bridge, obtains information such as an address, authentication information and the like of a virtual disk, generates a mounted xml configuration file, and then calls an attach_volume_ironic interface to mount the virtual disk to a cloud physical machine.
In some embodiments, the mounting the virtual disk to a cloud physical machine based on the configuration file includes: and adding a mounting virtual disk interface to the cloud physical machine, and inputting a cloud physical machine ID and a virtual disk ID into the mounting virtual disk interface. The cloud physical machine newly adds a virtual disk mounting interface to mount the virtual disk, and two interfaces are added with the essential entry: cloud physical machine id and virtual disk id. The code may be as follows:
attach_volume_ironic POST/v1/instances/{instance_id}
request body:{
"Volumeid": "volume_id", (string, cloud physical machine mounted virtual disk id)
"ProjectId": "project_id" (string, optional, project id where cloud physical machine is located)
}
In some embodiments, the mounting the virtual disk to a cloud physical machine based on the configuration file includes: and mapping the virtual disk to the cloud physical machine according to the type of the storage pool where the virtual disk is located. The connector information of os-bridge can be called, and the virtual disk is mapped to the cloud physical machine according to the type of the storage pool where the virtual disk is located.
In some embodiments, the mounting the virtual disk to a cloud physical machine based on the configuration file includes: and updating the ID of the virtual disk in the configuration file by using the local disk path, and writing the network card information communicated with the virtual disk into the configuration file. Updating the path of the local disk block_volume_device to an xml configuration file, wherein the updating content comprises two parts: the method comprises the steps that firstly, information of a mounted virtual disk is updated to uuid (Universally Unique Identifier, universal unique identifier) of a block_volume_device by volume_id information of a connector, so that ironic can directly acquire the information of the disk without a client, and subsequent unloading of the disk is facilitated; the second network card information communicated with the virtual disk, namely the management network information, and the disk mounted in the mode can be directly communicated with the storage rear end, so that the read-write operation of the disk is realized.
In some embodiments, the mounting the virtual disk to a cloud physical machine based on the configuration file includes: and establishing a connection relation between the cander and the ironic, and writing the connection relation into a database.

After the mounting is completed, the virtual disk can be seen by the cloud physical machine, and the virtual disk can be partitioned, formatted and the like, so that the virtual disk can be normally used.
The process of mounting the virtual disk on the cloud physical machine in the embodiment of the application can be as follows:
