Fig. 1 is a flowchart of an embodiment of a service recovery method according to an exemplary embodiment shown in this application, where the service recovery method may be applied to a storage device, in the embodiment of the application, the storage device is located in a storage system, and the storage system further includes a management device for managing the storage device, as shown in fig. 1, the service recovery method includes the following steps:
step 101: and writing the service configuration data corresponding to the service operated by the equipment into the backup file.
In an embodiment, according to an actual usage requirement, the management device may create a required service on the storage device through a management interface of the storage device, that is, after detecting that a user inputs corresponding service configuration data through a newly created service option on the management interface, the management device generates a service creation request based on the service configuration data, adds a service identifier corresponding to the newly created service option to the service creation request, and then sends the service creation request to the storage device, and the storage device obtains a corresponding command by using the service identifier carried in the service creation request, and executes the command by using the service configuration data, so as to create the corresponding service. Therefore, in the process of creating the service, the storage device may obtain the service configuration data carried by the service creation request, and write the obtained service configuration data into a preset backup file, so as to facilitate management of the service configuration data. The service identifier may be a number or a character, or may also be a combination of a number and a character, and the application is not limited herein. The storage device is pre-configured with the corresponding relation between the service identification and the command.
In another embodiment, since multiple types of services may be run on the storage device, the storage device may set a storage structure of service configuration data of the backup file in advance, so that the service configuration data included in each type of service is stored in a specified location, for example, a location 1 in the backup file is set to store service configuration data included in RAID (Redundant Array of independent Disk) services, and a location 2 stores service configuration data included in LVM (logical volume Manager) services.
Step 102: the backup file is transmitted to the management apparatus to cause the management apparatus to store the backup file in a specified storage medium.
In an embodiment, the storage device may send the backup file to the management device after receiving the export request sent by the management device, or may directly send the backup file to the management device after writing the service configuration data into the backup file, so as to avoid the storage device from failing to cause the loss of the backup file. The specified storage medium may be a hard disk or a memory, and the specified storage medium may be located on the management device or on another storage device other than the storage device, which is not limited herein.
In another embodiment, to ensure the security of the backup file, the storage device may encrypt the backup file using a preset encryption algorithm, and then send the encrypted backup file to the management device. It will be understood by those skilled in the art that the preset Encryption Algorithm may be DSA (Digital Signature Algorithm), IDEA (International Data Encryption Algorithm), etc., and the preset Encryption Algorithm may be implemented by related technologies, which will not be described in detail herein.
It should be noted that, when detecting that there is an update operation of the service configuration data, the storage device may update the backup file with the updated service configuration data, where the update operation of the service configuration data may include modification, deletion, and addition, and send the updated backup file to the management device. The backup file is updated by detecting the updating operation of the service configuration data, so that the real-time property of the backup file can be ensured.
Step 103: and after the failure of the equipment is recovered, receiving the backup file sent by the management equipment.
In an embodiment, when a storage device fails, data related to a service is lost, and an original service is lost, for example, in a process of creating a RAID service, metadata (attribute information for describing service data, for example, a storage location of the service data) is generated, and these metadata are usually stored in a disk, and after the storage device fails, the metadata stored in the disk is lost, so that a RAID service is lost, and therefore, after the device fails and recovers, a backup file sent by a management device may be received, so that the original service is recovered by using the backup file.
Step 104: and recovering the corresponding service according to the service configuration data in the backup file.
In an embodiment, after receiving the backup file sent by the management device, the storage device may store the backup file to a specified location, where a user may specify the storage location of the backup file in advance according to actual needs. Therefore, the storage device can acquire the backup file from the designated position, analyze the backup file to extract the service configuration data, acquire the command corresponding to the service configuration data, and execute the acquired command by using the service configuration data, thereby recovering the corresponding service.
As described in step 101, the backup file may be parsed according to the storage structure of the set service configuration data, for example, the service configuration data included in the RAID service may be extracted at position 1 of the backup file, and the service configuration data included in the LVM service may be extracted at position 2 of the backup file, so as to obtain a corresponding command according to the service identifier corresponding to each service, and execute the command by using the service configuration data, so as to recover the service environment.
In another embodiment, if the backup file is an encrypted file, the storage device may decrypt the backup file by using a decryption algorithm corresponding to the preset encryption algorithm in step 102, analyze the decrypted backup file to extract service configuration data, obtain a command corresponding to the service configuration data, and execute the obtained command by using the service configuration data, so as to recover the corresponding service.
As described in the foregoing embodiment, before the storage device fails, the service configuration data corresponding to the service operated by the device may be written into the backup file, and the backup file is sent to the management device, so that the management device stores the backup file in the specified storage medium, and thus, the security of the backup file may be ensured by the specified storage medium, and the problem of loss of the service configuration data due to failure of the storage device is avoided. After the storage device is recovered from the fault, the backup file from the management device can be received, and the corresponding service is recovered according to the service configuration data in the backup file, so that after the storage device is recovered from the fault, the original service environment can be recovered through the service configuration data execution command in the backup file, the management device does not need to re-create the service of the storage device, the continuity of the original service of the storage system is ensured, and the use experience of a user is further improved.
Fig. 2 is a flowchart of another embodiment of a service recovery method according to an exemplary embodiment of the present application, where the service recovery method may be applied to a management device in a storage system, and the storage system may further include a storage device. As shown in fig. 2, the service recovery method includes the following steps:
step 201: when the storage device is detected to be out of order, a backup file corresponding to the storage device is obtained from a specified storage medium, and service configuration data are recorded in the backup file.
When the management device detects that the storage device fails, if all data related to the service in the storage device are lost, the management device indicates that the service environment in the storage device is damaged, so that the backup file corresponding to the storage device can be acquired from a specified storage medium to prepare for recovery of the service environment.
In an embodiment, if the specified storage medium is located locally, the management device may directly obtain the backup file corresponding to the storage device from the local; if the specified storage medium is located on another storage device, the management device may acquire the backup file corresponding to the storage device from the other storage device.
Step 202: and sending the backup file to a storage device so that the storage device restores the corresponding service according to the service configuration data in the backup file.
After the management device sends the backup file to the storage device, the description of step 104 may be referred to for how the storage device recovers the corresponding service according to the service configuration data in the backup file, and details of the application are not described herein.
As described in the foregoing embodiment, when detecting that a storage device fails, the management device may acquire a backup file corresponding to the storage device from a specified storage medium, and send the backup file to the storage device, so that the storage device restores a corresponding service according to service configuration data in the backup file. The backup file corresponding to the storage device with the fault is stored on the designated storage medium instead of the storage device with the fault, so that the problem that the backup file is lost due to the fault of the storage device and the original service environment cannot be recovered can be avoided.
