Background
In a storage system with multiple controllers, IP arbitration is generally needed to judge the connection condition of nodes and the take-over condition of the nodes when a certain node fails; one deployment of IP arbitration is on a third party server; currently, the number of IP arbitration processes for connection by a storage cluster is limited, some systems are limited to 5, and records of the connection processes are stored by an array with the length of 5 (meanwhile, the IP arbitration process with the maximum connection of each node is 5); that is, one third-party server may open no more than 5 IP arbitration processes, or multiple third-party servers open no more than 5 IP arbitration processes altogether; when the total connection process number of the ipquoorum is not higher than 5; the multi-control system can normally operate and has certain capability of handling abnormal conditions.
But when a third-party server is in the situation of non-artificial active operation (for example, mouse problem generates multiple clicks, or the process is started too slowly to be existed), a plurality of IP arbitration processes are started (exceeding the requirement of system limit); when a node has a network failure and then recovers, the system will have a problem with a very high probability, taking a 4-control cluster as an example: assume the current connection situation is: the node1, the node2, the node3 and the node4 are respectively connected with 5 processes of ipquorum1-ipquorum5, so 5 IDs of the iPquuorum 1-ipquorum5 are stored in an IP arbitration connection array of the cluster, and the array is full; but an ipqurum6 process is always requesting to connect with node1, because the number of connections of node1 has reached 5, ipqurum6 is rejected, but the ipqurum6 process is still trying; when a network fault occurs in the node1, the connection between the node1 and the iqquorum 1-iqquorum 5 is disconnected, and the other 3 nodes in the cluster still maintain the connection with the iqquorum 1-iqquorum 5, so that the cluster senses 5 iqquorum; when the node1 network is recovered, the ipquorum6 is connected with the node1 before other processes, and is reported to the cluster, and because the connection array of the cluster is full, when receiving and storing the new ipquorum6, a fault occurs, and the cluster is abnormally crashed.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. 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.
In order to solve the problem of cluster system crash caused by ipquorum process connection after a certain node or certain nodes in the multi-control system are failed and recovered, the invention provides a multi-control cluster ipquorum connection method based on a resource lock; because a new iPquorum process is connected every time, a resource lock is required to be applied, the connection process can not overflow in an overrun mode, and further cluster abnormity can not be caused.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be an IP arbitration process quantity management and control system.
As shown in fig. 1, the method includes:
The cluster maintains a connection linked list, the elements are key value pairs (iquorumid, value), the iquorumid is the ID of the established connection iquorums, and the value is the connection times.
When the system receives an IP arbitration process connection request, the request is withheld and the target IP arbitration process ID and target node are parsed from the connection request.
In step 140, if the number of the currently used resource locks is lower than the set number threshold, the target IP arbitration process ID successfully applies for the resource lock, and requests the resource lock through the connection.
In order to facilitate understanding of the present invention, the IP arbitration process quantity management and control method provided by the present invention is further described below with reference to the principle of the IP arbitration process quantity management and control method of the present invention and the process of managing and controlling the IP arbitration process quantity in the embodiment.
Specifically, the IP arbitration process number management and control method includes:
s1, creating a process linked list and storing the key value pair of the existing IP arbitration process in the process linked list, wherein the key value pair comprises the ID of the existing IP arbitration process and the corresponding referred number, and the referred number is the number of nodes connected with the IP arbitration process.
S2, resolving the target IP arbitration process ID and the target node in the IP arbitration process connection request.
S3, if the matching key value pair of the target IP arbitration process ID does not exist in the process chain table, or the quoted number of the matching key value pair is 0, applying for a resource lock for the target IP arbitration process ID; and if the number of the currently used resource locks is lower than the set number threshold, the target IP arbitration process ID successfully applies for the resource locks and requests through the connection. Prior to requesting over the connection, the method further comprises: calling a reference linked list of a target node, and judging whether an IP arbitration process ID which is the same as the target IP arbitration process ID is stored in the reference linked list: if so, rejecting the connection request and returning a connection failure prompt; and if not, the connection request is passed. And if the number of the currently used resource locks is not lower than the set number threshold, rejecting the connection request and outputting a connection failure prompt.
The step introduces a reference linked list of the node, and avoids the repeated connection of the IP arbitration process and the node, which causes the waste of computing resources.
S4, if the matching key value pair of the target IP arbitration process ID exists in the process chain table, and the number of times of quoting of the matching key value pair is not 0, establishing the connection between the target IP arbitration process and the target node through the connection request; storing a target IP arbitration process ID in a reference linked list in a target node, wherein the reference linked list is used for storing the IP arbitration process ID connected with the node; and updating the referred times in the target key value pair matched with the target IP arbitration process ID in the process chain table into historical referred times plus 1.
If the matching key value pair of the target IP arbitration process ID exists in the process chain table, and the number of times of being quoted of the matching key value pair is not 0, the target IP arbitration process ID is the existing IP arbitration process of the system, and the existing IP arbitration process already applies for the resource lock, so that the resource lock does not need to be applied again.
S5, monitoring the connection condition of the existing IP arbitration process and the node, and if the connection disconnection of the IP arbitration process and the node is monitored, updating the number of times of reference of the matching key value pair of the IP arbitration process in the process chain table; and if the referred times of the matching key value pairs in the process linked list of the IP arbitration process are cleared, releasing the resource lock of the IP arbitration process.
The following description takes an example that the system can create 5 IP arbitration processes, please refer to fig. 2, which includes the following processes:
1. an initialization stage:
the cluster resource locks are initialized to 5; when a new IP arbitration process initiates a connection request, a resource lock is applied first;
the cluster maintains a connection linked list, wherein the elements are key value pairs (iPquorumID, value), the iPquorumID is the ID of the established connection iPquorum, and the value is the connection times;
each node in the cluster maintains a connection linked list, wherein the element is an iquorumID which represents the iquorumm connected with the node;
2. connection phase (take ipquorum1 request connection node1 as an example):
when an ipquoorm 1 requests to connect with node1, firstly, whether a key-value pair of ipquoorm 1 already exists in a cluster connection linked list is judged; if the connection between the iPquorum1 and the node1 is not established, the connection between any node in the cluster and the iPquorum1 is not established, and if the connection between the iPquorum1 and the node1 is to be established, a resource lock is required to be applied first; if yes, judging whether the connection really exists currently (value >0) or an invalid connection which is disconnected currently is connected previously (value is 0); if value >0, a node1 can autonomously judge whether to establish connection with ipquorum1 without applying for a resource lock; if the value is 0, the resource lock needs to be applied first;
for the situation that a connection request needs to apply for a resource lock first, if the ipquorum1 requests to connect the node1, the resource lock needs to be applied first; firstly, judging the number of the available resource locks which are not applied to the cluster, if the number is more than 0, executing the process of establishing the connection: (number of cluster resource locks is reduced by 1), node1 establishes connection with iquorum 1; an element ipquorum1 is added to a connection chain table of the node1, if no key (ipquorum 1) exists in a cluster connection chain table, an element (ipquorum1,1) is added, and if key (iprurum 1 exists and value (0) exists, value +1 is added; h ]; if the available resource lock is equal to 0, the connection is directly determined;
when the resource lock is not required to be applied, the fact that a node in the cluster is connected with the iquorum 1 is described; at this time, the node1 needs to judge whether the ipquorum1 exists in the own connection list, and if so, the connection of the ipquorum1 is rejected; if not, the process of establishing connection with iquorum 1 is executed: [ node1 ] is connected with ipquorum 1; an element ipquorum1 is added to a connection chain table of the node 1; adding 1 to a value corresponding to ipquorum1 in the cluster linked list; "C (B)
3. Ipquorum connection when a node fails and recovers:
taking the case that the node1 network fails, if the linked list before the node1 network fails, there are iPquorum1, iPquorum2, iPquorum3, iPquorum4 and iPquorum 5; there is also an ipquorum6 process that is denied a connection but is still trying. When node1 has a network failure, loses communication with other nodes of the cluster, or exits from the cluster, the cluster can update its connection linked list according to the connection linked list of node 1: (cluster in its linked list) subtract 1 from the corresponding value of the elements with key values ipquorum1, ipquorum2, ipquorum3, ipquorum4, ipquorum 5; if the value is reduced to 0, releasing a resource lock, and increasing the number of the cluster resource locks by 1; h ]; when the network fault of the node1 is recovered, ipquorum6 preemptively requests to establish connection with the node 1; then the method is repeated according to the step 2: process of connection phase ] to determine whether to connect or not.
The embodiment limits the number of the IP arbitration processes based on the resource lock, enhances the robustness of the system under the abnormal condition, can not depend on manual examination and limitation of the number of the IP arbitration processes for initiating the connection, and completely hands the abnormal judgment to the system for processing, so that the system is more robust and more humanized.
