Disaster tolerance processing between group, so that it is guaranteed that the continuity and availability of business.
The disaster tolerance processing method of the application is further illustrated below.
As shown in fig. 6, the disaster tolerance processing method of the present embodiment may include:
Step S201, monitoring node configuration production cluster, the corresponding backup cluster of production cluster and monitoring parameters information；
In the present embodiment, it can determine that monitoring node, monitoring node are located at the working cluster according to network topology
Except backup cluster, that is to say, that monitoring node is not belonging to production cluster, is not also not belonging to backup cluster.
After determining monitoring node, monitoring node can configure production cluster, that is, need to supervise which cluster
It surveys, then configures each production cluster and back up cluster accordingly.For some cluster, production cluster both can be used as, it can also
Using the backup cluster as other clusters.For example, it includes cluster A and cluster B, cluster A that monitoring node, which can configure production cluster,
Backup cluster be cluster B, the backup cluster of cluster B is cluster A, and the backup cluster of configuration cluster A is cluster C, cluster B
Backup cluster be cluster D.Monitoring node can be according to the resource distribution situation and/or operation shape of cluster each in distributed type assemblies
State specifically determines.
Monitoring parameters information may include monitoring heartbeat, that is, every how long to production cluster health status supervise
It surveys.Number of retries when monitoring parameters information can also include the link failure of access cluster.
Step S202, the state of production cluster and the corresponding backup cluster of production cluster is monitored；
Two kinds of services can be provided on monitoring node: network monitoring and health status are monitored, and network monitoring can monitor chain
Line state, monitor state monitor the operating status that can monitor cluster.
In this implementation, monitoring node can monitor the health status of production cluster and corresponding backup cluster in real time.It is assumed that
Production cluster is cluster A, and the backup cluster of cluster A is cluster B, then monitoring node will be according to configuration monitoring heartbeat to cluster A
It is monitored with the health status of cluster B.When cluster A is inaccessible, or other failures occurs, it is believed that cluster A's
At this moment abnormal state monitors the preparation that node carries out the standby migration of calamity.If cluster B's is in good condition, so that it may execute migration behaviour
Make.
In the present embodiment, monitoring node can judge the health degree of cluster according to the operating status of nodes all in cluster,
The health degree of cluster can also be judged according to the operating status of part of nodes, it can also be according to the operating status of cluster core node
Judge the health degree of cluster.
In addition, if cluster A condition is abnormal, monitoring node can be by the meter of all nodes of cluster A when carrying out calamity for migration
It calculates on resource migration to backup cluster, the computing resource on the node of selected focused protection can also be moved into backup cluster
On.
Step S203, abnormal state cluster, and the shape of the corresponding backup cluster of the abnormal state cluster are being monitored
When state is normal, the metadata for the abnormal state cluster that will acquire is synchronized on the corresponding backup cluster of the failed cluster；
Step S204, business datum of the abnormal state cluster in public storage area is mounted to the backup set
Group；
After monitoring node gets the metadata of abnormal state cluster, abnormal state cluster can be obtained according to metadata
Business datum volume identification；According to business datum volume identification, the business datum of abnormal state cluster is searched from data storage areas；
Then the business datum found is mounted to backup cluster.
Step S205, the business datum of the abnormal state cluster in backup cluster access public storage area；
In the present embodiment, business datum of the abnormal state cluster in public storage area is being mounted to institute by monitoring node
It, can be to backup set pocket transmission data carry success notification, to inform that backup cluster has other clusters after stating backup cluster
Business datum is mounted to its own cluster.Backup cluster is accessible public to deposit after receiving the data carry success notification
The business datum of abnormal state cluster in storage area domain.
Step S206, the computing resource of backup cluster starting state exception cluster；
Backup cluster can according to metadata and the computing resource that business datum starting state exception cluster is accessed, thus
It ensure that the continuity of abnormal state group service.
In the present embodiment, after this disaster tolerance is disposed, monitoring node can be corresponding to production cluster and production cluster
Backup cluster be updated, monitoring parameters information can also be updated.
It is further illustrated below by specific.
As shown in fig. 7, cluster A is as production cluster (i.e. production cluster), backup of the cluster B as cluster A in the scene
Cluster.
Public SAN (Storage Area Network, storage of the storage pool Storage Pool as cluster A and cluster B
Local Area Network) storage, cluster A and cluster B keep the continuous link stored to SAN；Computing resource is created on cluster A (for example, empty
Quasi- machine), the corresponding data of computing resource are stored in Storage Pool storage.
The health status that monitoring node monitors cluster A and cluster B is initiated if cluster A breaks down by monitoring node
The migration of computing resource acts, and the corresponding storage resource of the computing resources such as virtual machine is mounted on cluster B, and on cluster B
Starting, to realize that the calamity of computing resource is standby and high availability.
For example, operation has virtual machine 1, virtual machine 2 and virtual machine 3 on cluster A, it is assumed that the business datum of virtual machine 1 stores
On the volume 1 of storage pool, the business datum of virtual machine 2 is stored on the volume 2 of storage pool, and the business datum of virtual machine 3 is stored in
On the volume 3 of storage pool.As shown in figure 8, cluster B is just after the storage resource of cluster A is mounted on cluster B by monitoring node
The business datum of virtual machine 1 in accessible storage pool volume 1, storage pool roll up the business datum and storage of the virtual machine 2 in 2
The business datum of virtual machine 3 in pond volume 3, then according to the metadata for the business datum and cluster A being accessed starting cluster A
Virtual machine 1, virtual machine 2 and virtual machine 3.
It is run through the above technical solutions, the cluster of abnormal state can be moved on backup cluster, it is ensured that state
The continuity and availability of the business of abnormal cluster.Meanwhile when carrying out Data Migration, only by the metadata of abnormal state cluster
(such as configuration information) is synchronized to backup cluster, and the business datum of abnormal state cluster is without synchronizing, but passing through will be public
The business datum of abnormal state cluster in storage region is directly mounted on backup cluster, is opened on backup cluster to realize
The computing resource of dynamic state cluster.Therefore, data duplication amount when above-mentioned technical proposal disaster tolerance is handled greatly reduces, to keep away
Exempt to replicate the problem of total data bring calamity takes long time for process.
