[0078] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0079] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0080] In the server world, distributed storage clusters can utilize multiple servers to store data through a scalable system architecture. If the distributed storage cluster runs out of capacity or a node goes down, a new node (bare metal) needs to be added to the distributed storage cluster.

[0081] Figure 1a This is a schematic diagram of a node going online in a related technology provided in an embodiment of the present application. Figure 1a As shown, in the related art, in the process of adding the node to be put online to the distributed storage cluster, the user needs to manually add the node to be put online to the distributed storage cluster in the computer room (the room where the distributed storage cluster is placed). Figure 1a As shown in FIG, the process of manually adding the node to be put online to the distributed storage cluster includes manually installing the operating system in the node to be put online, manually upgrading the version of the node to be put online (upgrading the software version), and configuring the network.

[0082] In addition, in the process of manually adding the nodes to be put online to the distributed storage cluster outside the computer room, it is also necessary to use terminal devices to perform storage configuration, manual inspection, and storage pool reconstruction on the nodes to be put online. After the reconstruction is completed, the nodes to be put online are added to the distributed storage cluster.

[0083] However, the methods in the related art have the problem of low efficiency.

[0084] Based on the above technical issues, the technical concept of the embodiments of the present application is as follows: the first management node (any management node in the distributed storage cluster) can obtain the identifier of the node to be online in response to a node online request sent by a terminal device, and control the node to be online to display the device location based on the identifier of the node to be online. The first management node can obtain the boot configuration file corresponding to the operating system and the boot image file corresponding to the operating system stored by the first management node in response to verification information sent by the terminal device; wherein the verification information is input to the terminal device by the user based on the device location display of the node to be online. The first management node can install the operating system on the node to be online based on the boot configuration file and the boot image file, and add the node to be online to the distributed storage cluster.

[0085] Through the above method, the node can be put online without the user having to manually add the node to be put online to the distributed storage cluster in the computer room, thereby improving the efficiency of node online.

[0086] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0087] To facilitate understanding, first combine Figure 1b The application scenarios of the embodiments of the present application are described.

[0088] Figure 1b A schematic diagram of an application scenario provided in an embodiment of the present application.

[0089] like Figure 1b As shown, the application scenarios include:

[0090] Terminal device 10 and distributed storage cluster 20.

[0091] The distributed storage cluster 20 includes a control node 201 and multiple management nodes. Exemplarily, the distributed storage cluster includes a management node 202, a management node 203, and a management node 204. It is understood that multiple management nodes can form a management node cluster. Any of the multiple management nodes can be the first management node. Exemplarily, management node 202 can be the first management node.

[0092] In addition, the distributed storage cluster 20 may further include multiple storage nodes. For example, the distributed storage cluster may further include a storage node 205 and a storage node 206 .

[0093] In this application scenario, the control node 201 may be communicatively connected with the terminal device 10 .

[0094] The control node can also communicate with multiple management nodes.

[0095] The control node can also be connected to multiple storage nodes for communication.

[0096] It should be noted that Figure 1b This is only a schematic diagram of an application scenario provided by the embodiment of the present application. Figure 1b The actual form of the various devices included in the Figure 1b The interaction mode between devices is limited and can be set according to actual needs in the application of the solution.

[0097] Figure 2a A flowchart of a node online method provided in an embodiment of the present application is shown in FIG. Figure 2a As shown, the method includes the following steps:

[0098] S201: In response to a node online request sent by a terminal device, an identifier of a node to be online is obtained.

[0099] In this embodiment, the first management node may obtain a node online request sent by the terminal device. The first management node may respond to the node online request and obtain an identifier of the node to be online. In one implementation, the identifier of the node to be online may be a serial number of the node to be online.

[0100] The following describes a process in which the first management node obtains a node online request sent by a terminal device.

[0101] In one implementation,

[0102] The first management node may run a smart wizard.

[0103] The terminal device may generate a node online request in response to a user's operation on a graphical user interface (GUI) of the terminal device. For example, Figure 2b This is a workflow diagram for a node going online provided in the embodiment of this application. Figure 2b As shown, the terminal device can generate a node online request in response to the user's start operation on the GUI.

[0104] The control node may run an intelligent wizard, obtain a node online request, and send the node online request to the first management node.

[0105] The following describes a process in which the first management node obtains the identifier of the node to be brought online in response to the node online request.

[0106] In one implementation,

[0107] The first management node may obtain an Internet Protocol (IP) address of a controller in the node to be brought online. In one implementation, the controller may be a baseboard management controller.

[0108] In one implementation, when the node to be brought online is a newly added node or a node with a replaced mainboard, the IP address of the controller in the node to be brought online is the IP address of the controller in the node to be brought online, which is screened from multiple idle IP addresses by the first management node running a DHCP server and assigned to the controller in the node to be brought online.

[0109] In one implementation, when the node to be brought online is a down node, the first management node can directly obtain the IP address of the controller in the node to be brought online because the first management node has stored the IP address of the controller in the down node.

[0110] After obtaining the IP address of the controller in the node to be put online, the first management node can query the correspondence between the IP address and the serial number according to the IP address of the controller in the node to be put online, and determine the identifier (serial number) of the node to be put online.

[0111] In one implementation, the first management node may also determine the host name and host model corresponding to the node to be put online based on the IP address of the controller in the node to be put online. It should be noted that the host name, host model, and serial number can all be understood as node information of the node to be put online.

[0112] In one implementation,

[0113] The node online request may include the identifier of the node to be online.

[0114] The first management node may obtain the identifier of the node to be brought online in the node bringing online request.

[0115] S202: According to the identifier of the node to be online, the node to be online is controlled to perform device positioning display.

[0116] In this embodiment, the first management node may control the node to be online to perform device location display according to the identifier of the node to be online.

[0117] In one implementation,

[0118] The first management node may determine a duration variable corresponding to the node to be online based on the identifier of the node to be online, wherein the duration variable indicates the duration for the node to be online to join the distributed storage cluster.

[0119] When the value in the duration variable (online_time) corresponding to the node to be online is a preset value (such as zero), the first management node can control the node to be online to light up an indicator light and / or output a preset sound to display the device location. It should be noted that the device location display allows users to quickly find the node to be online from multiple nodes in the computer room. In one implementation, the first management node can control the node to be online to light up an indicator light and / or output a preset sound by sending an Intelligent Platform Management Interface (IPMI) command to the node to be online. In one implementation, the node to be online can continuously light up an indicator light at intervals of two seconds based on the IPMI command.

[0120] In one implementation, the preset value can be zero. It should be noted that if the node to be brought online is a newly added node or a node whose mainboard has been replaced, the value in the duration variable corresponding to the node to be brought online is zero. If the node to be brought online is a down node, the value in the duration variable corresponding to the node to be brought online is zero. Based on the above, it can be seen that if the value in the duration variable corresponding to the node to be brought online is zero, the node to be brought online is a node that needs to be brought online.

[0121] Through the above-mentioned approach, node online errors are avoided, which may cause the first management node to online a node that has completed the online process, thereby causing a node failure.

[0122] S203: In response to the verification pass information sent by the terminal device, obtain the boot configuration file corresponding to the operating system and the boot image file corresponding to the operating system stored in the first management node.

[0123] In this embodiment, the first management node can store the boot configuration file corresponding to the operating system and the boot image file corresponding to the operating system. In addition, the first management node can also store the software packages corresponding to various software programs and the configuration files corresponding to various software programs. In one implementation, the first management node can reserve 20GB of storage space for storing the boot configuration file corresponding to the operating system, the boot image file corresponding to the operating system, the software packages corresponding to various software programs, and the configuration files corresponding to various software programs.

[0124] In one implementation, Figure 2c This is a functional diagram of a first management node provided in an embodiment of the present application. Figure 2cAs shown, the first management node can have network management, version image management, and configuration management functions. The network management function means that the first management node can run a DHCP server and a TFTP server, and can also run an IP scanning tool. The version image management function means that the first management node can manage the operating system's boot configuration files, boot image files, and software packages (or upgrade packages) corresponding to each software stored on the first management node. The configuration management function means that the first management node can manage the configuration files corresponding to each software.

[0125] When the node to be put online is displayed with the device location, the user can check in the computer room whether the node to be put online with the device location display is a bare metal node that needs to be put online. If so, the terminal device can respond to the user's operation on the graphical user interface and obtain verification information.

[0126] The first management node may obtain the verification pass information sent by the terminal device, and obtain the boot configuration file corresponding to the operating system and the boot image file corresponding to the operating system stored in the first management node.

[0127] The verification pass information is displayed by the user based on the device location of the node to be online and input into the terminal device.

[0128] S204: Install the operating system in the node to be put online according to the boot configuration file and the boot image file, and add the node to be put online to the distributed storage cluster.

[0129] In this embodiment, the first management node may install (load) the operating system in the node to be put online according to the boot configuration file and the boot image file, and add the node to be put online to the distributed storage cluster.

[0130] Figure 2d A schematic diagram of the process of installing an operating system provided in this application.

[0131] Next, combine Figure 2b , describes the process of the first management node installing the operating system in the node to be put online according to the boot configuration file and the boot image file.

[0132] In one implementation,

[0133] 1. The first management node can run the IPMI tool to send a Preboot Execution Environment (PXE) boot command to the node to be brought online.

[0134] 2. The node to be online can send a temporary IP address application request to the first management node through the in-band management network card. It can be understood that the first management node can run a DHCP server to obtain the temporary IP address application request sent by the node to be online.

[0135] 3. The first management node can send a temporary IP address and the network location of the bootstrap file to the node to be online. The temporary IP address is used for communication by the node to be online.

[0136] 4. The node to be online can request the first management node to transmit the bootstrap file. It can be understood that the node to be online requests the first management node to transmit the bootstrap file based on the temporary IP address and the network location of the bootstrap file.

[0137] 5. The first management node can send the bootstrap file to the node to be online.

[0138] 6. The node to be put online can execute pxelinux.0 according to the bootstrap file. It should be noted that pxelinux.0 is the boot image file.

[0139] 7. The node to be brought online requests the pxelinux.cfg file from the first management node. It should be noted that the pxelinux.cfg file is a boot configuration file that contains the configuration parameters required for booting.

[0140] 8. The first management node transmits the pxelinux.cfg file to the node to be put online.

[0141] 9. The node to be put online requests the system kernel and root files from the first management node.

[0142] 10. The first management node transmits the system kernel and root files to the node to be put online. It should be noted that the system kernel and root files are necessary for the operating system to start.

[0143] 11. The node to be launched is started.

[0144] Additionally, in one implementation,

[0145] The first management node may also obtain the software packages corresponding to the various software and the configuration files corresponding to the various software stored in the first management node before adding the node to be put online to the distributed storage cluster.

[0146] The first management node can configure the node to be online based on the software package and configuration file corresponding to each software. In other words, the first management node can manage version upgrades (software package version management) and import configuration files.

[0147] Next, the configuration process of the first management node is described.

[0148] In one implementation,

[0149] After installing the operating system on the node to be put online, and before adding the node to the distributed storage cluster, the first management node can establish a Secure Shell (SSH) session with the node to be put online using the node's temporary IP address and the default account and password. The first management node can send a port-shutdown command (such as an iptables command) to the node to shut down the storage service port. This prevents the node from storing data to be stored (data that needs to be stored in the distributed storage cluster), which could cause an alarm.

[0150] The first management node can control the node to be brought online to perform hard disk partitioning and network recovery. In one implementation, if the node to be brought online is down, since the hard disk of the node to be brought online is not faulty, the node to be brought online can, after identifying the hard disk's partition table information (including the hard disk's partition layout information), mount the hard disk according to the partition table information. Furthermore, the first management node can obtain network configuration information corresponding to the node to be brought online and send the network configuration information to the node to be brought online, so that the node to be brought online can perform network recovery based on the network configuration information. In one implementation, if the node to be brought online is newly added, that is, if the management database does not store the serial number of the node to be brought online, the first management node can, in response to the node type (node ​​role) selection information sent by the terminal device, determine the partitioning method corresponding to the node type (e.g., storage node or compute node) in the node type selection information, partition the hard disk, and mount the hard disk according to the partition table information of the hard disk partition. The first management node can also determine an IP address corresponding to a node to be online from multiple idle IP addresses, and control the node to be online to perform network recovery processing based on the IP address. In one implementation, the first management node can also control the graphical user interface of the terminal device to display the IP address so that the user can verify the IP address, and after the verification is passed, control the node to be online to perform network recovery processing based on the IP address. In one implementation, the terminal device can also obtain a new IP address input by the user after the user fails to verify the IP address. The first management node can obtain the new IP address sent by the terminal device, and control the node to be online to perform network recovery processing based on the new IP address. It can be understood that in one implementation, the new IP address input by the user can be different from the last digit of the IP address displayed on the graphical user interface of the terminal device.

[0151] The first management node may also control the node to be put online to perform hard disk partitioning and network recovery processing, and then, according to the node type of the node to be put online, send a service startup command corresponding to the node type to start the storage service of the node to be put online.

[0152] In one implementation, the first management node can also perform inspections on the nodes to be brought online. If the inspection fails, the first management node can control the graphical user interface of the terminal device to display an exception message. The user can perform exception handling based on the exception message displayed on the terminal device. In one implementation, after the user performs exception handling, the first management node can respond to the terminal device's instruction to continue inspection and perform a full or incremental inspection on the nodes to be brought online.

[0153] In one implementation, the first management node may further determine whether the distributed storage cluster meets the node online conditions based on the fault information and load information of the distributed storage cluster. If not, the first management node may control the graphical user interface of the terminal device to display a reminder message.

[0154] In one implementation, the first management node can also control the node to be online to open the storage service port in response to the information sent by the terminal device to start bringing the node to be online online, so that the node to be online can store the data to be stored (data that needs to be stored in the distributed storage cluster). In addition, the first management node can also control the node to be online to reconstruct the storage pool, and control the time variable corresponding to the node to be online to start timing, so that it reflects the time it takes for the node to be online to join the distributed storage cluster. In addition, it should be noted that the first management node can determine the reconstruction speed of the storage pool based on the load information of the distributed storage cluster. In addition, the first management node can also shut down the DHCP server and TFTP server running on the first management node. In one implementation, the first management node can also update the configuration library.

[0155] Beneficial effects of this embodiment: In this embodiment, the first management node (any management node in the distributed storage cluster) can obtain the identification of the node to be online in response to the node online request sent by the terminal device, and control the node to be online to perform device positioning display based on the identification of the node to be online. The first management node can obtain the boot configuration file corresponding to the operating system stored by the first management node and the boot image file corresponding to the operating system in response to the verification pass information sent by the terminal device; wherein the verification pass information is input to the terminal device by the user based on the device positioning display of the node to be online. The first management node can install the operating system in the node to be online based on the boot configuration file and the boot image file, and add the node to be online to the distributed storage cluster. In the above manner, the node can be online without the user manually adding the node to be online to the distributed storage cluster in the computer room, thereby improving the efficiency of node online.

[0156] The following describes the process of each management node in the distributed storage cluster obtaining the target file.

[0157] Figure 3 A second flow chart of a node online method provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method includes the following steps:

[0158] S301: Acquire a target file sent by a control node in a distributed storage cluster.

[0159] In this embodiment, the control node in the distributed storage cluster can obtain the target file sent by the terminal device.

[0160] The target file includes at least one of the following: a boot configuration file corresponding to the operating system, a boot image file corresponding to the operating system, a software package corresponding to at least one software, and a configuration file corresponding to at least one software.

[0161] The first management node may obtain the target file sent by the control node.

[0162] S302: Storing the target file.

[0163] In this embodiment, the first management node may perform storage processing on the target file after obtaining the target file.

[0164] S303: Determine the second management node.

[0165] In this embodiment, the first management node may determine the second management node after storing the target file. In one implementation, each management node may store the priorities of multiple management nodes. The first management node may determine the second management node based on the priority of each management node.

[0166] The second management node is a management node at the next level below the first management node. The priority of the second management node is lower than that of the first management node. For example, the first management node is a management node with a priority of 1. The second management node is a management node with a priority of 2. It should be noted that, in one implementation, a smaller value of the priority indicates a higher priority. In one implementation, the priority of the second management node is lower than that of the first management node, and the priority of the second management node is higher than that of other management nodes.

[0167] S304: If it is determined that the second management node does not store the synchronization mark, send the target file to the second management node.

[0168] In this embodiment, the first management node may determine whether the second management node stores a synchronization flag, wherein the synchronization flag is used to indicate that the second management node has synchronized the target file.

[0169] The first management node may send the target file to the second management node when it is determined that the second management node does not store the synchronization mark.

[0170] The second management node can perform storage processing on the target file.

[0171] The second management node may determine a next-level node (a third management node) of the second management node.

[0172] The second management node may determine whether the next-level node of the second management node stores a synchronization mark. The second management node may send the target file to the next-level management node of the second management node if it is determined that the next-level node of the second management node does not store a synchronization mark.

[0173] The third management node (a node next to the second management node) may determine a node next to the third management node.

[0174] The third management node may determine whether the next level node of the third management node stores a synchronization mark. If the third management node determines that the next level node of the third management node does not store a synchronization mark, the third management node may send the target file to the next level node of the third management node.

[0175] Through the above-mentioned step-by-step synchronization method, each management node can store target data.

[0176] S305: Control the second management node to store a synchronization flag.

[0177] In this embodiment, after sending the target file to the second management node, the first management node may control the second management node to store the target file, and then control the second management node to store a synchronization mark.

[0178] Additionally, in one implementation,

[0179] The first management node may determine a total number of at least one stored target file stored by the first management node, wherein the stored target file is a target file or a historical target file.

[0180] The first management node may determine the storage time of each stored target file.

[0181] When the first management node determines that the total number reaches a preset threshold, the first management node may determine a target file to be deleted from at least one stored target file based on the storage time of each stored target file and the preset threshold.

[0182] The first management node may perform deletion processing on the target file to be deleted.

[0183] It should be noted that other management nodes in the management node cluster can also determine the target file to be deleted and delete it. The specific implementation process is the same as the process of the first management node determining the target file to be deleted and deleting it, and will not be repeated here.

[0184] Additionally, in one implementation,

[0185] The control node in the distributed storage cluster can monitor the resource usage score of each management node.

[0186] When monitoring that the resource usage score of at least one management node has changed, the control node may obtain the updated priority of each management node according to the resource usage score of each management node.

[0187] The control node may determine whether all management nodes store a synchronization flag when determining that the updated priority of at least one management node is inconsistent with the priority of the management node (priority before updating).

[0188] The control node may send the updated priority of each management node to each management node when it is determined that each management node stores the synchronization flag.

[0189] The beneficial effects of this embodiment include: a first management node can obtain a target file sent by a master node in a distributed storage cluster; the target file includes at least one of the following: a boot configuration file corresponding to an operating system, a boot image file corresponding to an operating system, a software package corresponding to at least one software, and a configuration file corresponding to at least one software. The first management node can store and process the target file. The first management node can determine a second management node; the second management node is a next-level management node of the first management node; the second management node has a lower priority than the first management node. If the first management node determines that the second management node does not store a synchronization flag, the first management node can send the target file to the second management node for storage and processing. If the next-level management node of the second management node does not store a synchronization flag, the first management node can send the target file to the next-level management node of the second management node. After sending the target file to the second management node, the first management node can control the second management node to store the synchronization flag. By synchronizing the target files of management nodes step by step, each management node can store the target file. Consequently, when each management node is selected as the first management node, it can use the stored target file to bring the node to be brought online, thus avoiding the situation where a single management node failure prevents the node from being brought online. In addition, by synchronizing the target files of the management nodes step by step, the synchronization pressure of the first management node can be reduced.

[0190] The following describes a process in which a control node in a distributed storage cluster determines a first management node from a plurality of management nodes included in the distributed storage cluster.

[0191] Figure 4 A schematic diagram of a node online method provided in an embodiment of the present application Figure 3 ,like Figure 4 As shown, the method includes the following steps:

[0192] S401: The control node determines the priority of each management node according to the acquired IP address and / or resource usage index of each management node.

[0193] In this embodiment, the distributed storage cluster includes a control node, wherein the control node can run cluster management software to manage each node in the cluster.

[0194] The distributed storage cluster includes multiple management nodes. In one implementation, the control node may determine multiple management nodes from the distributed storage cluster in response to the user's confirmation information and according to the identifiers of the multiple management nodes in the determination information.

[0195] In one implementation, the control node may obtain the IP address of each management node.

[0196] In one implementation, the control node can obtain resource usage indicators from each management node. For example, the resource usage indicators may include at least one or more of the following: CPU usage, memory usage, remaining hard disk storage space, hard disk performance, and network bandwidth. It should be noted that hard disk performance can be measured by the hard disk's data transfer rate, random read / write rate, sequential read / write rate, latency, and so on.

[0197] The control node may determine the priority of each management node according to the IP address and / or resource usage index of each management node.

[0198] In one implementation,

[0199] The control node can compare the IP addresses of the management nodes and determine the priority of each management node according to the size of the IP address of each management node. For example, as the size of the IP address of the management node gradually increases, the priority of the management node gradually decreases.

[0200] In one implementation,

[0201] The control node may determine the resource usage score of each management node based on the resource usage index of each management node. In one implementation, the control node may determine the resource usage score of the management node based on the following formula.

[0202]

[0203] Wherein, j represents the jth management node; w represents the weight value of each resource usage indicator; v represents the resource usage indicator; and k represents the number of resource usage indicators.

[0204] The control node may determine the priority of the management nodes based on the resource usage score of each management node. In one implementation, the lower the resource usage score, the higher the priority of the management node.

[0205] In one implementation,

[0206] The control node can determine the resource usage score of each management node based on the resource usage indicators of each management node.

[0207] If the control node determines that the resource usage scores of the management nodes are consistent based on the resource usage scores of the management nodes, it can determine the priority of each management node based on the IP address of each management node. In one implementation, the control node can determine the priority of each management node based on the size of the IP address of each management node. For example, as the size of the IP address of the management node gradually increases, the priority of the management node gradually decreases.

[0208] The control node may determine the priority of each management node based on the resource usage scores of each management node if the resource usage scores of each management node are inconsistent. In one implementation, the lower the resource usage score, the higher the priority of the management node.

[0209] S402: The control node determines a first management node from a plurality of management nodes included in the distributed storage cluster according to the priorities of the management nodes in the distributed storage cluster.

[0210] In this embodiment, after determining the priority of each management node in the distributed storage cluster, the control node may determine the first management node from the multiple management nodes included in the distributed storage cluster according to the priority of each management node.

[0211] In one implementation, the control node may determine a management node with the highest priority among the multiple management nodes as the first management node.

[0212] In one implementation, for any management node, the control node may send the priority of each management node to the management node after determining the priority of each management node.

[0213] Beneficial effects of this embodiment: In this embodiment, the control node can determine the priority of each management node based on the acquired IP address and / or resource usage indicators of each management node. The control node can determine the first management node from the multiple management nodes included in the distributed storage cluster based on the priority of each management node in the distributed storage cluster. This method can quickly determine the first management node, improving the efficiency of determining the first management node.
