Technical Field
The invention belongs to the technical field of network bandwidth management, and particularly relates to a super-convergence system host maintenance method, device, equipment and storage medium.
Background
The super-fusion infrastructure is a unified system of software definition, and is a technical architecture which integrates resources such as calculation, network and storage as infrastructure, can be selected, combined and defined according to specific service system requirements, and can conveniently and quickly build a data center and deploy a service system. In the super-convergence architecture, each node is a computing node, a network node and a storage node, and in the case that maintenance scenarios within expectations are required, such as: when the firmware is upgraded, the Kernel is upgraded or the hardware is replaced, the host needs to be powered off offline. Because the system architecture is a super-fusion system, the phenomenon of cluster computing resource reduction and storage resource reduction can be accompanied when the nodes are offline. From the perspective of computing resources, a user needs to ensure that the remaining computing resources of the cluster meet the requirement that a virtual machine running on a target node continues to run, otherwise, the service continuity of the user is affected; from the perspective of storage resources, a user needs to ensure that the remaining storage resources of the cluster meet the requirement that the storage resources included in the target node can perform data recovery, otherwise, a situation that part of data copies of the cluster are not in accordance with expectations occurs, and system stability is affected.
In the existing scene, a user needs to perform the following steps to maintain a host:
1. judging whether the target host meets the offline requirement or not through the console, and checking the operation condition of the key component;
2. migrating the running virtual machine on the target host to other hosts in the cluster in a live migration mode, so as to ensure that user services are not influenced;
3. taking the target host offline, and performing expected internal maintenance actions such as firmware upgrading, fault hardware replacement and the like;
4. after the maintenance is finished, migrating the original virtual machine of the target host to ensure that the computing resources of different nodes in the cluster are uniformly distributed;
5. and checking the running condition of the host to ensure that the host recovers the health state.
By adopting the scheme, the method has the following disadvantages:
1. a large number of checking actions are required to ensure that the target node is offline and cannot influence the cluster;
2. the running condition of the virtual machine needs to be recorded and manually migrated to ensure that the computing resources are uniform after the maintenance action is finished;

Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and distinctly aiding in the description of the embodiments of the invention.
It should be noted that all directional indicators (such as up, down, left, right, front, and back \8230;) in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicators are changed accordingly.
Example one
In the current scenario, a maintenance mode is introduced to relieve the mental burden of the user in maintaining the target host: the method has the advantages of reducing operation interaction flow, reducing data recovery amount generated in the maintenance process of the target host, and automatically migrating the virtual machine on the target host. The states of 'maintenance mode' and 'entering maintenance mode' are introduced according to the state of the host in the cluster, so that the cluster can be ensured to execute the scheduling action of the computing resource correctly when the host enters the maintenance mode. Please refer to fig. 1, which is a host state machine of the host maintenance method of the super-fusion system.
The host maintenance process is divided into the following stages: pre-inspection, preparation for entering maintenance, preparation for exiting maintenance inspection, and exiting maintenance.
Referring to fig. 2, the purpose of the pre-check is to check whether the target host can currently satisfy the enter maintenance mode condition. The states of the cluster operation and maintenance component, the computing component and the storage component are respectively checked. The method comprises the steps that all check items are independently and concurrently executed and are not mutually sensed, the check items are divided into necessary check items and secondary check items, if the necessary check items do not pass, a user cannot enable a target host to enter a maintenance mode, if the secondary check items do not pass, the user is prompted to not pass the reason, and the user can select to enable the target host to enter the maintenance mode.
Referring to fig. 3, after the user initiated pre-check passes, the user may choose to enter the target host into the maintenance mode, and during the entering process, the following actions are automatically performed:
1. setting the host state as 'ready to enter maintenance';
2. performing secondary pre-inspection to prevent a user from not initiating an entering action in time after the pre-inspection is finished, so that the cluster state is inconsistent with the pre-inspection state, and subsequent action execution fails;
3. setting host non-schedulable, preventing a user from creating and running a virtual machine on a target host during entry;
4. migrating the target host virtual machine, and migrating the target host to other nodes of the cluster;
5. setting a target node as a storage maintenance mode to reduce the data recovery amount generated by a user in the subsequent maintenance period;
6. the host state is set to "maintenance".
After the above actions are completed, referring to fig. 4, the user can observe that the target host is in the "maintenance mode" state in the console, and at this time, the user can perform the subsequent offline maintenance action.
After the off-line maintenance is completed, the user starts the target host, the service on the target host can be started automatically, after the host is started, the user can initiate the quit maintenance check through the console, and if the check is passed, the user can quit the maintenance of the target host. The complete process is as follows
1. Initiating a preparation quit maintenance check, checking the running state of a target host, and waiting for receiving a quit request initiated by a user after the check is passed;
2. setting a target node as a non-storage maintenance mode;
3. setting the target host to be in a schedulable state to allow subsequent auto-migration virtual machine actions to be schedulable to the target host;
4. migrating the virtual machine, and migrating the original virtual machine of the target host to the target node;
5. and (4) exiting the maintenance.
Example two
The embodiment provides an implementation mode based on the host maintenance method and the device pre-inspection of the super fusion system.
The pre-inspection of the embodiment ensures that all inspection items are independently decoupled, whether the inspection items are called by the maintenance mode device is not required to be sensed, each inspection item is realized as an independent Job Task type function, when the pre-inspection is triggered, a Task center Leader generates a Task set of the pre-inspection Job according to the related information of the current platform and the target node, and the Task set is uniformly submitted and scheduled. And after all the check items are executed, uniformly returning check results. The current Task center does not support the saving of the results of specific Task execution, the Task center is planned to be improved to support the characteristics, and the pre-inspection results are saved in specific Job Task information.
During the process of entering the maintenance mode, the target host computer performs a secondary check. Because each check in the pre-check needs to be recorded in the database after the execution of each check is completed, if the pre-check is changed into a single Task mode, compatibility adjustment is performed on the specific check implementation, and unnecessary conditions are introduced, so that the API scheduling mode is uniformly adopted for secondary check in the maintenance mode process.
Specifically, whether the cluster has a host in a state related to a maintenance mode is:
and checking whether the host computer of the cluster is in a maintenance mode related state or not by inquiring the database record. All maintenance mode tasks are submitted and executed through the task center, the task center assigns a unique UUID to ensure that only the same preposed inspection task can be operated at the same time, and the cluster can only have the same host to operate in a maintenance mode.
Cluster and target host health status checking:
the check that the host enters maintenance mode should be based on: judging whether the host computer can influence user service (calculation and storage) when off-line maintenance after entering a maintenance mode, classifying checking items according to the basis, and dividing the checking items into calculation component checking, storage component checking and operation and maintenance component checking, wherein when the platform is Elf/SMTZBS, the detection items comprise virtual machine detection, and when the platform is Vmware, the detection items remove virtual component detection:
1. the operation and maintenance component detection comprises the following steps:
and if the cluster exists, checking to fail.
2. The storage component detection comprises:
whether single copy data exist or not and the single copy data are on the target node, if so, the check is failed; (ZBS-meta _ text can only return all the copy cases at present, and self-filtering is needed; ZBS is needed to obtain the specified chunk text support according to chunk id);
zookeeper, if cluster 3 node, except target node, has abnormal node, then check not pass; if cluster 5 node, except the target node, has more than 1 abnormal node, then the check fails;
zbs-meta, the cluster has at least one survival meta node except the target node, if the condition is not satisfied, the detection is not passed;
whether a node in the cluster is in a storage maintenance mode exists, if the node in the cluster is in the storage maintenance mode, checking that the node does not pass;
whether there is data recovery for the cluster (if so, storage maintenance mode cannot be entered);
capacity detection, namely, the current residual capacity of the cluster, namely the residual capacity of the node, is larger than the used capacity of the node, and is only displayed and is not used as a basis for whether a maintenance mode can be entered or not;
3. the computing component detecting comprises:
mongo, if cluster 3 node, except the target node, has an abnormal node, then the check does not pass; if cluster 5 node, except the target node, has more than 1 abnormal node, then the check fails;
whether the target node storage network can be connected or not is judged, and if not, the target node storage network is checked to be not passed;
job-center-worker, whether the target node service is running or not, if not, checking that the service does not pass;
libvirtd; whether the target node service is running or not, if not, checking that the service does not pass;
whether a virtual machine on a target host can be live migrated;
whether the virtual machine on the target host can be cold migrated.
In the super-fusion system, each independent node is a storage node from the perspective of a storage component, the storage system adopts a copy mechanism to ensure data availability, after the nodes are offline, data recovery can be automatically triggered after cluster detection, and when the host offline is an operation within expectation, the time consumed by maintenance can be greatly reduced by avoiding the data recovery. The addition of the storage maintenance mode support can prevent cold data on the host in the storage maintenance mode from generating data recovery. If the system finds that one copy in a certain data block is in the storage maintenance mode, the copy is only marked to be recovered, but a recovery command is not really triggered, so that the aim of reducing the data recovery amount is fulfilled.
From the perspective of a computing component, a user service virtual machine may run on any one host in a cluster, and when a certain host is maintained, the virtual machine needs to be migrated first, so that it is ensured that user services are not affected. When a user enters a certain host into a maintenance mode, the host is firstly set to be non-dispatchable on a computing component level, and it is ensured that an unexpected virtual machine is not created/migrated to a target host in the entering process. Before the virtual machine is migrated, pre-scheduling check of virtual machine migration is carried out, if the pre-scheduling execution is completed, subsequent migration actions are carried out, and if the pre-scheduling execution fails, the virtual machine cannot be migrated, and the virtual machine cannot enter a maintenance mode. In the process that the target host enters the maintenance mode, in order to ensure that the migration influence range of the virtual machines is as small as possible, serial independent migration is selected for migration, only one virtual machine is migrated each time, the subsequent virtual machines are migrated after the current virtual machine is migrated successfully, if the current virtual machine is migrated successfully, the complete entering process fails, and the subsequent virtual machines are not migrated any more.
The target host enters a maintenance mode to be executed as an asynchronous task, the task does not comprise subtasks, and the complete control flow is logically controlled by the device, so that the device is ensured not to depend on the outside. In the task implementation, all steps in the entering process are guaranteed to be idempotent, so that reentrant under an abnormal scene is guaranteed. Whether the asynchronous task is executed successfully or fails, the state of the target host is finally set to be an expected state, and the consistency of the states is ensured.
And when the maintenance of the target host is finished and the target host is online again, the target host needs to be quitted from the maintenance. Before the real exit, the method firstly carries out the preparation exit maintenance check to check whether part of key services on the target host meet the exit condition, and if not, the exit of the maintenance mode is prohibited. And if the condition is met, performing subsequent exit action. In the exit process, the storage component exits the storage maintenance mode from the target node to enable the target node to be on line again; the computing component marks the target host as a schedulable state, and migrates the automatic migration virtual machine triggered in the process that the target host enters the maintenance mode back to the target host, so as to ensure the balance of cluster computing resources. The method is the same as that the target host computer is prepared to enter the maintenance mode, the maintenance check is prepared to exit and is executed as an asynchronous task, the task does not comprise subtasks, and the target host computer state is set to be the expected state finally no matter whether the exit is successful or failed, so that the state consistency is ensured.
EXAMPLE III
The embodiment provides a specific implementation mode of virtual machine migration based on the super fusion system host maintenance method and device.
During the host entering maintenance mode, virtual machine migration out and back actions are involved. The state and configuration of the virtual machine can affect whether the virtual machine is migrated back successfully or not. The configuration items related to the virtual machine being unable to migrate comprise:
1. whether the virtual machine is in a running state;
2. whether the virtual machine contains a pass-through device;
3. and whether the state of the virtual machine is changed after the virtual machine is migrated.
The above various combination scenarios are specifically divided as follows:
the first scenario is:
the second scenario is:
the third scenario is:
a fourth scenario:
preferably, during the process of entering the target host into the maintenance mode, multiple steps and component interactions are designed, and if more computing resources are present on the target host, the overall time consumption may be on the order of minutes, thus requiring the ability to support the user to cancel the entry. Before the maintenance mode entry/exit asynchronous task starts, it is recorded whether the current step supports a cancel action and whether the current task is marked as cancelled. Each step is checked for the current task flag bit before execution, providing an update unmarked bit capability through the API. If the marking bit is True, canceling the execution of the subsequent steps, and marking the whole task as cancelled; if the flag bit is False, it indicates that the user has not initiated a cancel action, and the subsequent steps are continued until the next step is executed.
