Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.
In order to facilitate understanding of the technical solutions provided in the present application, the following description will first be made on the background of the present application.
The inventor finds in research on modifying configuration files of nodes in a conventional distributed storage system that, in the conventional technology, when mapping volume creation is performed, the system may add configuration information of the mapping volume to configuration files of nodes in a cluster. However, when a node has a service anomaly, the system sends a service anomaly prompt to prompt a user that the node fails to add the configuration information of the mapping volume in the configuration file of the node, and does not perform further processing operation on the failed node.
Based on this, the embodiments of the present application provide a method and an apparatus for implementing node information consistency in a distributed storage system, when a mapping volume is newly created, setting configuration information of the mapping volume, and detecting a service state of each node in the distributed storage system, when a certain node is out of service, creating a timing detection process for the node to detect the service state of the node, when the node is recovered to be normal, extracting the configuration information of the mapping volume from other nodes, and synchronizing the configuration information to a configuration file of the node, thereby ensuring that the configuration information of each node in the system is consistent, and further ensuring that each node can provide block storage service for a user.
Referring to fig. 1, the figure is a schematic diagram of a framework of an exemplary application scenario provided in an embodiment of the present application. The method for achieving consistency of node information in the distributed storage system provided by the embodiment of the present application may be applied to the distributed storage system 20, and the system may include a server node 1 and a server node 2.
In actual application, a user may trigger a request for creating a mapping volume through the client 10, the distributed storage system 20 creates the mapping volume according to the creation request, and detects the service state of each node in the system, and when an exception occurs in a certain service node, a detection process is created to detect the service state of the node at regular time. When the node returns to normal, the configuration information of the mapping volume is extracted from other nodes and synchronized into the configuration file of the node, so that the configuration information of each node is ensured to be consistent.
Those skilled in the art will appreciate that the block diagram shown in fig. 1 is only one example in which embodiments of the present application may be implemented. The scope of applicability of the embodiments of the present application is not limited in any way by this framework.
It should be noted that the client 10 in the embodiment of the present application may be installed in a terminal, which may be any existing, developing or future developed user equipment capable of interacting with the distributed storage system 20 through any form of wired and/or wireless connection (e.g., Wi-Fi, LAN, cellular, coaxial cable, etc.), including but not limited to: existing, developing, or future developing smartphones, non-smartphones, tablets, laptop personal computers, desktop personal computers, minicomputers, midrange computers, mainframe computers, and the like. It should also be noted that the distributed storage system 20 in the embodiment of the present application may be an example of an existing, developing or future developed device capable of providing data storage application services to users. The embodiments of the present application are not limited in any way in this respect.
In order to facilitate understanding of the technical solutions provided by the present application, the storage snapshot type conversion method provided by the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, which is a flowchart illustrating a method for implementing node information consistency in a distributed storage system according to an embodiment of the present application, where the distributed storage system includes at least two nodes, as shown in fig. 2, the method may include:
s201: and responding to the triggering operation of a user, creating a mapping volume, and setting the configuration information of the mapping volume.
In this embodiment, a user may initiate a request for creating a mapping volume through a client according to a storage requirement of the user, and the distributed storage system creates the mapping volume according to the creation request. Meanwhile, the configuration information of the mapping volume may be set, specifically, information such as an ID of the mapping volume, creation time, and storage space of the mapping volume may be set.
S202: and detecting whether the service of the node is normal or not aiming at any node.
In practical applications, after the mapping volume is created, the system adds the configuration information of the mapping volume to the block storage service configuration file of each node, so that the mapping volume may have a mapping on each node.
In order to avoid addition failure caused by a failure of a node in the system, before adding the configuration information, the service state of each node in the system may be detected to determine whether the node can add the configuration information.
In specific implementation, after the mapping volume is created, an instruction for modifying the configuration file may be sent to each node, and each node may be detected according to the sent modification instruction. Each node in the system corresponds to one configuration file.
S203: when the service of the node is abnormal, a timing detection process is established to detect the service state of the node at regular time.
In this embodiment, when detecting that the storage service of the node block is abnormal, a timing detection process is created for the node, so as to detect the service state of the node at regular time. Wherein the service state of the node comprises normal and abnormal.
In practical applications, a node fast storage service may be shut down or fail, so that configuration information of a node configuration file cannot be modified, and therefore, when a node is out of service, the node is periodically detected to detect whether a service state of the node is changed.
S204: when the service state of the node is recovered to normal, the configuration information of the mapping volume is extracted from other nodes and synchronized to the configuration file of the node.
In this embodiment, when the block storage service of the abnormal node returns to normal, the configuration information of the newly created mapping volume may be extracted from the configuration files of other nodes, and the configuration information is synchronized into the configuration file of the node, so that the configuration information of each node in the system is consistent, and it is ensured that the newly created mapping volume has a mapping on each node, that is, each node stores the relevant information of the mapping volume, such as the ID, the creation time, and the storage space of the mapping volume. And the other nodes are nodes without abnormal service in the system, and the configuration file of the node is added with the configuration information of the mapping volume.
In practical application, when S202 detects that a node service is normal, the configuration file of the node without the abnormality is modified, and the configuration information of the mapping volume is added to the configuration file corresponding to the node. When the nodes with abnormal service recover to be normal, the configuration information of the mapping volume is extracted from the nodes, and the extracted configuration information is added into the configuration file corresponding to the nodes which have recovered to be normal.
In a possible implementation manner, in a specific implementation, when a node service abnormality is detected, the system may record information of the abnormal node, where the information may include an ID of the node with the service abnormality and a time when the service abnormality occurs. When the node returns to normal, the configuration information of the mapping volume can be extracted from the other nodes according to the information, and the mapping volume is synchronized into the configuration file of the node.
In specific implementation, when a node returns to normal, the system may extract the configuration information of the mapping volume created after the time point from the rest nodes according to the recorded time information, thereby ensuring the integrity of the configuration information of the node configuration file and no addition of repeated configuration information.
In a possible implementation manner, when all nodes in the system complete configuration file modification, the system may send modification success prompt information to the client to prompt the user that the configuration files of all nodes are successfully modified, so as to facilitate the user to perform subsequent storage operation.
The method comprises the steps that firstly, a new mapping volume can be created according to the triggering operation of a user, the configuration information of the mapping volume is set, whether the service of each node is normal or not is detected, and if the service of the node is normal, the configuration information of the mapping volume is added into a configuration file corresponding to the node; if the service of a certain node is abnormal, a timing detection process is established for the node to perform timing detection on the abnormal service node, and when the service of the node is recovered to be normal, the configuration information of the mapping volume is extracted from the added node and is synchronized into the configuration file of the node, so that the configuration information of each node in the distributed storage system is kept consistent, and further the block storage service of each node in the system is ensured to be normal.
For convenience of understanding, referring to a framework diagram for implementing node information consistency in a distributed storage system shown in fig. 3, firstly, according to a trigger request of a user, a mapping volume is created in the storage system, for each node, whether the service of the node is normal or not is detected, and if the service of the node is normal, configuration information of the mapping volume is added in a configuration file corresponding to the node. If the node service is abnormal, establishing a timing monitoring process to monitor the service state of the node and monitor whether the service of the node is normal again, if so, extracting the configuration information of the mapping volume from the configuration files of other nodes and carrying out information synchronization on the node; and if not, continuously monitoring the service state of the node.
