Background
In a distributed storage system, windows clients typically use samba services to access storage clusters. Samba will store the mount information of the client in the smbXsrv _ client _ global. The SmbXsrv _ client _ global. tdb database is a key _ value type key value pair, and mainly stores a key value converted by a client _ guid (client global unique identifier) of a client, node information of a service end providing service and the like. And when the client is disconnected within 10s, the server clears the mounting information from the database.
When the client accesses the storage cluster by using the samba service, the service end node queries whether the smbXsrv _ client _ global.tdb database of the service end node and the smbXsrv _ client _ global.tdb databases of other nodes in the cluster contain the mounting information of the client _ guid, and if not, the record is stored in the database of the node. If the value is not the same as the vnn value of the client mounting node, the mounting failure is caused because the vnn value of the request node is not consistent with the vnn value inquired in the database.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In a first aspect of the embodiments of the present invention, an embodiment of a method for client mount in multiple channels is provided. Fig. 1 is a schematic diagram illustrating an embodiment of a method for client mount in multiple channels according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, responding to a negotiation request sent by a client received by a server, and acquiring a global unique identifier of the client from the negotiation request;
s2, forming a sharing identification by the global unique identifier and the IP address of the server, and converting the sharing identification into a key value through a hash algorithm;
s3, judging whether a record of the key value exists in the database; and
s4, responding to the record of the key value not existing in the database, writing the key value into the database, and establishing the connection between the server and the client to form mounting.
SMB (Server Message Block) is a shared transmission protocol used between different network nodes, and provides shared service of resources such as files and printers for different computers in local area network. Samba: and the SMB protocol is realized and is used for providing the application of the shared service from the Linux server to the Windows client.
When the samba opens the multi-channel and cluster mode, when the client sends a negotiation request to the server, the request includes information such as client _ guid (client global unique identifier) of the client and SMB protocol version number supported by the client. The server side analyzes information such as client _ guid from a data packet of a nexation request of the client side, converts the client _ guid into a key (key) value through a hash algorithm, then searches whether a record containing the key value is contained in an smbXsrv _ client _ global.tdb database of the node and other nodes in the cluster, and if the record contains the key value, compares vnn information stored in the database with vnn of the node processing the nexation request to determine whether the record is consistent. If the two are not consistent, the service end returns a failure to the connection, which results in mounting failure.
The reason why the above problem occurs is that after the client mounts and disconnects for the first time, the time for the database to clear the mount information is 10 seconds, if the mount information of the last time is not cleared in the database, that is, the client uses smb mount again within 10 seconds (that is, the same client has the same client _ guid and the same key value converted by the hash algorithm), the same key value may cause mount failure, and if the IP (Internet Protocol ) of the server used for mounting for two times is different, that is, the different vnn of the two times of mount failure may also cause mount failure.
The invention provides a new mounting mode to solve the problem of mounting failure caused by the fact that a client mounts a node 2 and acquires data vnn from the node 1, which is different from the node, after the client mounts the node 1 and unloads the node and the database does not clear mounting information in the database in the node 1. The main idea of the embodiment of the invention is to combine the global unique identifier of the client with the IP address of the server, and convert the combination into a key value through a hash algorithm, and the specific steps are as follows:
responding to a negotiation request sent by a client received by a server, and acquiring a global unique identifier of the client from the negotiation request. When the samba opens the multi-channel and cluster mode, when the client sends a negotiation request to the server, the request includes information such as client _ guid (client global unique identifier) of the client and SMB protocol version number supported by the client. The server side analyzes information such as client _ guid from a data packet requested by the negotion of the client side.
And forming a shared identifier by the global unique identifier and the IP address of the server, and converting the shared identifier into a key value through a hash algorithm. The client _ guid is the identification of the client, and the client _ guids of different clients are different. When the client side is mounted, the client _ guid and the IP address of the service end node are combined into a shared identification, and the shared identification is converted into a key value through a hash algorithm and stored in the smbXsrv _ client _ global.
In some embodiments, the method further comprises: and setting a VNN value according to the IP address of the server, and binding the VNN value with the key value. Subsequently, when the same key value is generated by the new mount, whether the VNN value is the same or not needs to be judged, so that the VNN value needs to be bound with the key value, and the key value can be quickly determined when the corresponding key value is found subsequently.
In some embodiments, the forming the globally unique identifier and the IP address of the server into a shared identifier includes: and converting the global unique identifier and the IP address of the server into binary numbers, and adding the two binary numbers after conversion to form a shared identifier. The IP address may be converted into 1111 when the IP address is 1.1.1.1, or the global unique identifier of the client may be converted into a binary number by ASCII code, and then the binary number converted by the global unique identifier of the client and the binary number converted by the IP address of the server are added to form the shared identifier, or in some embodiments, the binary number converted by the IP address of the server may be directly added to the end of the binary number converted by the global unique identifier of the client, for example, the binary number converted by the IP address of the server is 1111, and the binary number converted by the global unique identifier of the client is 1011101, so that the combination is 10111011111.
And judging whether a record of the key value exists in a database. And responding to the condition that no record of the key value exists in the database, writing the key value into the database, and establishing the connection between the server and the client to form mounting.
In some embodiments, the method further comprises: responding to the record of the key assignment in the database, and judging whether the VNN value corresponding to the key assignment of this time is the same as the VNN value corresponding to the key assignment in the database; and responding to the VNN value corresponding to the key value of this time is the same as the VNN value corresponding to the key value in the database, and establishing connection between the server and the client to form mounting.
When the client unloads the mount, the connection information is not cleared in the database, and the ip of the server is replaced and mounted again, the new key value converted by the combination of the client _ guid and the ip of the server is different from the key value mounted last time, the mount information cannot be inquired in the database, and the database record is newly built according to the key value, namely, the mount can be carried out. If the same ip is used for the two mounts, the same key value is calculated for the two mounts, but if the service end ip matches, vnn for the two mounts match, and the mounts may be successful.
In some embodiments, the method further comprises: and in response to that the VNN value corresponding to the key value of this time is different from the VNN value corresponding to the key value in the database, notifying the client to send the negotiation request again after waiting for a preset time. If the VNN value corresponding to the key value of this time is different from the VNN value corresponding to the key value in the database, it is indicated that a problem may occur in a certain process, and the negotiation request may be sent again for mounting after waiting for a preset time.
In some embodiments, the establishing the connection between the server and the client to form the mount includes: and establishing a session between the server and the client, and establishing a connection tree based on the session. The client side uses the SMB protocol and the server side to mount the client side interactively, and the method comprises the following steps: in the negotiation process, the client and the server negotiate information such as version number using an SMB protocol, perform password verification in the session establishment process, perform connection establishment in the tree _ connect process, and the like.
In some embodiments, the method further comprises: and responding to the disconnection of the client side and the server side, and clearing the mounting information corresponding to the server side in a database. And when the client is disconnected from the server within 10 seconds, the mounting information corresponding to the server is cleared in the database.
The embodiment of the invention forms the shared identification by the global unique identifier of the client and the IP address of the server, converts the shared identification into the key value by the Hash algorithm, if the new server is inconsistent with the original server, the key value is inconsistent, the mounting can be carried out, if the new server is consistent with the original server, the VNN value is the same, the mounting can be carried out, and therefore, the probability of cluster access failure caused by the fact that the client uses different servers in SMB service is reduced.
It should be particularly noted that, the steps in the embodiments of the method for client mount in multiple channels can be mutually intersected, replaced, added, and deleted, so that these reasonable permutation and combination transformations as well as the method for client mount in multiple channels shall also belong to the scope of the present invention, and shall not limit the scope of the present invention to the embodiments.
