Abstract
The invention provides a method for managing a distributed type mirror image storage block device based on network, which relates to the technology field of disk data management, and guarantees source the networks on a source end and a target end to be communicated with each other, wherein a resource management group is built in a same resource management platform, and the source end (a local host) and the target end (a target host) are integrated into a same resource management group of the uniform resource management platform. The method for managing the distributed type mirror image storage block device based on the network allows users to build a real-time mirror image which uses a block device as a unit for local data on a remote machine, thereby being capable of achieving distributed storage of data block. Dual-direction heartbeat detection is added, can send out alarm when one end pings different opposite ends in 20s, and records fault situations at the moment. The method for managing the distributed type mirror image storage block device based on the network has the advantages of centralized management and intuition and the like.
Description
Technical field
The present invention relates to data in magnetic disk administrative skill field, particularly relate to a kind of management method of network distributed mirrored storage block device.
Background technology
Along with DASD sharing large-scale application is in teaching, experiment and production system, in the production application of reality, serve as more and more heavier role, experienced easily for people bring, serve efficiently.But along with the progress in epoch, be limited to shared disk Single Point of Faliure, I/O bottleneck etc., the fail safe of original shared disk, expansibility have not reached demand, so in the urgent need to safer, more efficient, better scheme carry out management data.
Summary of the invention
In order to solve this problem, the present invention proposes a kind of management method of network distributed mirrored storage block device.The method is a kind of storage solution of highly reliable, efficient, High Availabitity, has centralized management, the advantage such as directly perceived.
The present invention is based on network, by Internet Transmission, source (this locality) data are copied to destination end (far-end) in real time in the mode of data block, do not need the intervention thought in a replication process.And real-time monitoring is carried out to source and destination, after having one end to break down, can alarm mechanism be started, notify keeper, and accurate recording fault time, failure cause.Keeper can recover it according to concrete fault log, very reliably practical.
Technical scheme of the present invention is:
By the theory of distributed synchronization mirror image, first source and destination network interworking is ensured, establishing resource management group in same resource management platform, concentrates on source (local host) and destination (destination host) in the same resource management group of unified resource management platform.In this way, allow user to set up a real-time mirror image of carrying out in units of block device local data on the remote machine, thus can realize carrying out distributed storage to data block.And add two-way heartbeat detection, when the different opposite end of one end ping in 20s, will warning be sent, and record now failure condition.
Also the data on multiple stage machine can be copied in real time on same machine simultaneously, by creating multiple resource management group in management platform, different source machines be added in different resource management groups, and divides multiple disk space corresponding thereto.Realize by this way multisystem, how, multi-platform data back up in realtime, improving also achieving of fail safe can high scalability.
The present invention can be used among High Availabitity (HA), and it is similar to network DNC-1 function.When data being write source file system, data also will be sent in network on destination, are recorded in the same manner in a file system.Source (host node) can ensure real-time synchronization with the data of destination (slave node).When source end system breaks down, destination main frame also can remain with a identical data, can continue to use.
Source (this locality) data are copied to destination end (far-end) in the mode of data block by Internet Transmission by the present invention in real time, do not need the intervention thought in a replication process.And real-time monitoring is carried out to source and destination, after having one end to break down, can alarm mechanism be started, notify keeper, and accurate recording fault time, failure cause.Keeper can recover it according to concrete fault log, very reliably practical.
The invention provides a kind of safer, management method of more easily expanding, use one can be replaced to share the mode of dish battle array.Because data are present on source end host and destination main frame simultaneously, avoid the accident causing loss of data because of shared disk fault.Also the data on multiple stage machine can be copied in real time on same machine simultaneously, can high scalability also achieving of fail safe of raising.During switching, as long as distance host uses the Backup Data of local terminal, just can proceed service.
Accompanying drawing explanation
Fig. 1 is management platform schematic diagram of the present invention;
Fig. 2 is workflow diagram of the present invention.
Embodiment
More detailed elaboration is carried out to content of the present invention below:
It is the management platform schematic diagram of complete network distributed mirrored storage block device in Fig. 1, it is synchronous that source end host disk and destination host disk carry out real-time mirror image block by network, wholely synchronously carry out based on block device, user can be monitored whole synchronizing process by management platform and the timely process of problem.Thus realization copies in real time to local disk, the function such as high safety, high availability of long-distance disaster.
The main usage monitoring of management platform and management ensure distributed mirrored storage block device, and embodiment is as follows:
(1) according to the actual requirements the steps such as format carry are carried out to local disk;
(2) disk the same with local side is dissolved at destination form;
(3) configuration network, enables local side and destination realize network service;
(4) install and log in management platform, newly-built real-time synchronization group, adding source and destination resource to group, and add heartbeat monitor;
(5) configured, started mirror image.The function such as real-time storage, fault detect, failover of distributed mirrored storage block device can be realized;
(6) daily record when a problem occurs, by management platform carries out real-time monitoring and process to fault.
Claims (3)
1. a management method for network distributed mirrored storage block device, is characterized in that,
First ensure source and destination network interworking, establishing resource management group in same resource management platform, concentrates in the same resource management group of unified resource management platform by source and destination; In this way, allow user to set up a real-time mirror image of carrying out in units of block device local data on the remote machine, thus can realize carrying out distributed storage to data block; And add two-way heartbeat detection, when the different opposite end of one end ping in 20s, will warning be sent, and record now failure condition; When source end system breaks down, destination main frame also can remain with a identical data, can continue to use.
2. method according to claim 1, is characterized in that,
Data on multiple stage machine can be copied in real time on same machine, by creating multiple resource management group in management platform, different source machines be added in different resource management groups, and divides multiple disk space corresponding thereto.
3. method according to claim 1 and 2, is characterized in that,
When data being write source file system, data also will be sent in network on destination, are recorded in a file system in the same manner, ensure that the data of source and destination can real-time synchronization.
