Detailed description of the invention
Fig. 1 is the step schematic diagram of shared storage method of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, including the following steps the present invention provides a kind of shared storage method of cloud service cluster：
1, physical store is connected to server, storage pool is constructed to physical store by operating system；
Specifically, the physical store is using in monolithic hard disk, a group hard disc group, mechanical hard disk, solid state hard disk, flash disk
It is any, the storage pool by increase physical store carry out dilatation or by reduce physical store carry out capacity reducing.
2, storage pool is divided into multiple logical volumes；
Specifically, the logical volume has the function of dilatation, capacity reducing, deletion, backup and recovery, and when logical volume dilatation,
The capacity of logical volume is no more than the remaining active volume of storage pool, and when logical volume capacity reducing, the capacity of logical volume is not less than storage pool
In storing data actual capacity.
3, the example A carry of cloud service is on a certain logical volume A, and authorizes example A and write power, and the state of example A is believed
Breath is written in logical volume A；
Specifically, the status information includes the log-on message, connection type, software and hardware resources configuration information of example.
4, it when dilatation example B, by example B carry on logical volume A, and authorizes example B and reads power；Example B, which is read, to patrol
The status information of the example A in volume A is collected, and then example B inherits the state of example A.
Dispatching method of the invention is described in detail below with reference to embodiment and attached drawing.
Embodiment：
The operation system of certain company exploitation needs to save the log-on message of user, and (log-on message is stored in document form
Local file system) so that user is not necessarily to execute register when accessing the operation system next time, to improve the easy-to-use of system
Property.
With the growth of userbase, in order to cope with the concurrent access request of a large number of users, share server stress, the public affairs
The operation system is transformed and is migrated to cloud platform by department.The cloud platform can according to user's amount of access number, it is dynamic to increase
The running example for few operation system that adds deduct.
If certain user M has accessed an example A of operation system, and leaves log-on message, example A is by the log-on message
Store local volume.After a period of time, cloud platform needs to increase the example of operation system according to amount of access judgement to reduce individually
The load of example then creates the example B of the operation system.User M has accessed again operation system at this time, cloud platform by its
Access request distributes to example B processing, and user M did not execute register on example B, and example B also just can not be at this
Ground inquires the log-on message of user M, so user M needs to be logged in again to verify identity, reduces user experience.
In the above scene, shared storage method through the invention creates a logic in storage server in advance
A is rolled up, logical volume A is remotely mounted to local in creation by the example A of operation system.When user M accesses operation system and leaves
After log-on message, example A stores the log-on message to local, since logical volume A is from long-range carry, so the description
The file of log-on message actually has been written into long-range logical volume A, and example A and unaware.Subsequent cloud platform dilatation goes out
Example B, also carry remote logical volume A in an identical manner.When example B is accessed in user M, example B is attempted in local lookup
The log-on message of user M, because logical volume A is from long-range carry, actually example B is an attempt in remote logical volume
The log-on message of user M is searched on A.Because example A had stored the log-on message of user M on logical volume L before,
Example B can get log-on message, so that the log-on message of authorised user M, eliminates the process logged in again, improve user
Experience.
In conclusion state when shared storage method of the invention can be realized the instance migration of cloud service is inherited and shape
State is synchronous, improves the operational efficiency of cloud service.
