Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of an implementation of a service processing method of a storage cluster in an embodiment of the present invention, where the method may include the following steps:
s101: and receiving a service processing request, and analyzing the service processing request to obtain a node selection rule of the service to be processed corresponding to the service processing request.
When the service processing is required, a service processing request can be sent to the service processing center, and the service processing center receives the service processing request. The service processing request may be configured with a node selection rule for selecting a node required for processing the service to be processed. After receiving the service processing request, the service processing center may parse the service processing request to obtain a node selection rule of the service to be processed corresponding to the service processing request.
S102: and calculating the corresponding target main node number and the target backup node number according to the node selection rule.
The nodes in the storage cluster can be numbered in advance, and the determination of the target master node number of the target master node and the target backup node number of the target backup node required for the service processing of the service to be processed is related to a node selection rule, for example, each node in the storage cluster is divided into a first node group, a second node group and a third node group according to the sequence of the preset node numbers, the node selection rule can be that the number of the node which is coded first in the first node group is selected as the target master node number, and the number of the next coding node of the node which is coded first is selected as the target backup node number. After the node selection rule is obtained through analysis, the corresponding target main node number and the target backup node number can be calculated according to the node selection rule.
S103: and calling the node management array through the running state machine to judge whether the target main node number and the target backup node number are both valid, if so, executing the step S104, and if not, executing the step S105.
And each array bit of the node management array stores a preset node number or an invalid value for marking the running state of each node in the storage cluster.
The node management array for managing the node numbers of the nodes in the storage cluster can be preset, and each array bit of the node management array stores a preset node number or an invalid value for marking the running state of each node in the storage cluster, namely for each array bit, when the node corresponding to the preset node number of the array bit in the pre-deployment state is in a normal running state, the array bit is marked as a corresponding preset node number, and when the node corresponding to the preset node number of the array bit in the pre-deployment state is in an exit state, the array bit is marked as a preset invalid value.
And after the target main node number and the target backup node number are obtained through calculation, the node management array can be called by operating the state machine to judge whether the target main node number and the target backup node number are both effective. When it is determined that both the target master node number and the target backup node number are valid, it may be indicated that both the target master node corresponding to the target master node number and the target backup node corresponding to the target backup node number are in a normal operating state, step S104 may be continuously performed, and when it is determined that an invalid node number exists in the target master node number and the target backup node number, it may be indicated that a node that has exited exists in the target backup node corresponding to the target master node number and the target backup node number corresponding to the target master node number, and in this case, step S105 may be continuously performed.
S104: and selecting a target main node corresponding to the target main node number and a target backup node corresponding to the target backup node number from the storage cluster, and performing processing operation on the service to be processed by using the target main node and the target backup node.
When it is determined that the target master node number and the target backup node number are both valid, the target master node corresponding to the target master node number and the target backup node corresponding to the target backup node number may be selected from the storage cluster, and the target master node and the target backup node are utilized to perform processing operation on the service to be processed.
S105: and carrying out node selection rule adjustment prompting operation.
When the invalid node number exists in the target main node number and the target backup node number, a node selection rule adjustment prompting operation can be performed, so that a service processing request sending end can conveniently adjust a node selection rule according to the node selection rule adjustment prompting information, the effective target main node number and the effective target backup node number are selected, the target main node corresponding to the target main node number and the target backup node corresponding to the target backup node number are finally selected from a storage cluster, and the target main node and the target backup node are used for processing the service to be processed.
The method provided by the embodiment of the invention is applied to receive the service processing request and analyze the service processing request to obtain the node selection rule of the service to be processed corresponding to the service processing request; calculating the corresponding target main node number and the target backup node number according to the node selection rule; calling a node management array through an operating state machine to judge whether the number of the target main node and the number of the target backup node are both valid; each array bit of the node management array stores a preset node number or an invalid value for marking the running state of each node in the storage cluster; if yes, selecting a target main node corresponding to the target main node number and a target backup node corresponding to the target backup node number from the storage cluster; and processing the service to be processed by using the target main node and the target backup node. The node numbers are set for the nodes in the storage cluster, the node management array is set to store the node numbers, and the validity of the node numbers is identified by using the array bits in the node management array, so that the validity of the selected target main node number and the target backup node number is determined, fault misjudgment is avoided, and normal operation of service processing is ensured.
It should be noted that, based on the first embodiment, the embodiment of the present invention further provides a corresponding improvement scheme. In the following embodiments, steps that are the same as or correspond to those in the first embodiment may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the following modified embodiments.
Example two:
referring to fig. 2, fig. 2 is a flowchart of another implementation of a service processing method for a storage cluster in an embodiment of the present invention, where the method may include the following steps:
s201: and receiving the service processing request, and analyzing the service processing request to obtain a node selection rule of the service to be processed corresponding to the service processing request.
S202: and determining a target array position of the target main node in the node management array according to the node selection rule.
The storage cluster is composed of a plurality of storage devices including a main node and a backup node.
A storage cluster may contain multiple storage devices, with each storage device being comprised of a primary node and a backup node. The determination of the target group digit of the target master node in the node management array is related to the selected node selection rule, if it is assumed that 5 storage devices are in total in the storage cluster, each storage device comprises two nodes, namely the number of the nodes in the storage cluster is 10, the node management array is set to store the node numbers of the nodes, the 10 group digits of the node management array are 0-9 respectively, the node selection rule can be set to be that the last digit in the node management array is used as the target group digit of the target master node, and therefore the target group digit is 9. After the node selection rule is obtained through analysis, the target array position of the target main node in the node management array can be determined according to the node selection rule.
It should be noted that, for the master node and the backup node in the same storage device, only a one-to-two relationship between the storage device and the node is indicated, specifically, the master-backup relationship between the two nodes is determined by a specific service, and for the same storage device, when it is used for processing different services, the master-backup relationship between the two nodes may be different.
S203: and calculating the number of the target main node by combining the target digit group position and the node number calculation formula:
array bits = storage device number 2+ node number.
The target main node number comprises a storage device number of a target storage device where the main node is located and a node number of a corresponding node.
The node number calculation formula may be preset, and may be set as follows according to a one-to-two relationship between the storage device and the node, and a storage relationship between each array bit in the node management array and each node number of each node included in each storage device, respectively: group bit = storage device number × 2+ node number, where the storage device number is an IoGroup number, and the node number may represent a Position (Position number) of the storage device in the storage device, so that the node number calculation formula may be written as: group bit = IoGroup number × 2+ Position number. In the above example, the storage device IoGroup numbers in the storage cluster may be set to be 0 to 4, and the Position numbers of the two nodes included in each storage device are 0 and 1, respectively. And writing the node number of the Position 0 of the Iogroup 0 into the 0 th array bit of the node management array, writing the node number of the Position 1 of the Iogroup 0 into the 1 st array bit of the node management array, and so on. After determining the target digit group position of the target master node in the node management digit group, the target master node number may be calculated by combining the target digit group position and the node number calculation formula, that is, the storage device number of the target storage device where the master node is located and the node number of the corresponding node may indicate the target master node number.
S204: and determining the number of the other node except the number of the target main node in the storage device number corresponding to the number of the target main node as the number of the target backup node.
Because a service to be processed is mostly processed and completed by two nodes corresponding to the same storage device, after the number of the target master node is calculated, the number of another node except the number of the target master node in the number of the storage device corresponding to the number of the target master node can be determined as the number of the target backup node.
S205: and calling the node management array through the running state machine to judge whether the target main node number and the target backup node number are both valid, if so, executing step S206, and if not, executing step S207.
And each array bit of the node management array stores a preset node number or an invalid value for marking the running state of each node in the storage cluster.
S206: and selecting a target main node corresponding to the target main node number and a target backup node corresponding to the target backup node number from the storage cluster, and performing processing operation on the service to be processed by using the target main node and the target backup node.
S207: and carrying out node selection rule adjustment prompting operation.
S208: and when detecting that a node joining event or a node quitting event occurs, suspending the processing operation of the service to be processed.
In the process of service processing, a node joining event or a node exiting event may occur, and when the node joining event or the node exiting event is detected, the processing operation of the service to be processed may be suspended, thereby avoiding adverse effects on the current service processing operation due to the change of the node running state in the storage cluster.
S209: and carrying out validity updating operation on the preset node number of the corresponding array position in the node management array according to the currently occurring node adding event or node exiting event.
When a node join event or a node exit event is detected, validity updating operation may be performed on the preset node number of the corresponding group bit in the node management array according to the node join event or the node exit event that occurs currently, to support the above example, for example, if a node of Position No. 1 of IoGroup No. 0 exits, the group bit No. 1 of the node management array is set to an invalid value. By quickly updating the preset node number of the corresponding array bit in the node management array, the service processing center is ensured to smoothly and efficiently complete the related service.
Corresponding to the above method embodiment, the embodiment of the present invention further provides a service processing device of a storage cluster, and the service processing device of the storage cluster described below and the service processing method of the storage cluster described above may be referred to correspondingly.
