10G, but the operating system in virtual machine thinks or has 100G disks), when disk uses full 10G soon, simplify configuration program
Can automatically apply expanding disk space (also crying dilatation) for virtual machine, thus can be with piecemeal increase disk space, most
It is eventually virtual machine distribution 100G spaces.
Due to there is no the complete disk space of primary distribution when virtual machine is created, and when virtual machine runs, need dynamic
State is virtual machine application disk space, it is therefore desirable to a kind of method regularly monitoring virtual machine, when magnetic disk of virtual machine insufficient space
When just at once for its application disk space.
In prior art, it will usually whether need dilatation for regular check virtual machine using special supervision timer.
If necessary to dilatation, then dilatation request is sent, then the supervision timer is just no longer actually operated, unless it is complete to receive dilatation
Into.
But in view of the unreliability of network, a retransmission timer is generally also needed to, please for resending dilatation
Ask.When at a certain time interval, if do not receive the confirmation message to dilatation all the time, resending dilatation please
Ask.
And the operation that dilatation is asked is completed using two intervalometers, compare the resource of consumption system.Virtual machine is being used
During, disk space can be ceaselessly used, when Insufficient disk space, need (to assume to apply for virtual machine application space
1G), due to network problem, for a long time could may really apply to disk space, and in the middle of the process of whole request dilatation,
Virtual machine may also ceaselessly consuming disk space, and virtual machine may be it is desirable that 2G rather than 1G spaces, and existing skill
Art is only to resend dilatation message, also just says dilatation size or the 1G for sending, and this just cannot meet virtual machine at all
Actual demand.

Fig. 2 is the structural representation of the disk space flash chamber that the embodiment of the present invention 2 is provided.
Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement
Example is not limited to the scope of the present invention for illustrating the present invention.
Fig. 1 shows that the embodiment of the present invention 1 provides a kind of disk space expansion method, including：
S11, the confirmation of the non-dilatation in space of acquisition disk, obtain the Spatial Residual value of the disk.
In this step, it should be noted that in embodiments of the present invention, for obtain the space of disk whether dilatation or
Whether having sent the concrete steps of dilatation includes：
S111, in program operation process, obtain the dilatation mark bit variable of the disk space.In this step, when
During system runs program, each program information can be read.In program information, the use information in meeting storage disk space.
One dilatation flag bit can be set in the information, and the dilatation flag bit can be made a distinction with the first variable and the second variable as mark.
Generally, can be identified by False and True in the flag bit.
If S112, dilatation mark bit variable are False, it is determined that the non-dilatation in space of the disk.
In this step, when it is False to read dilatation mark bit variable, illustrate that disk space does not also carry out dilatation.
Now, system can obtain the current spatial value and space use value of disk, so as to obtain Spatial Residual value.
In addition, when it is True to read dilatation mark bit variable, illustrating to have have sent dilatation request.
S12, determine that the Spatial Residual value is not more than preset alert value, send that the disk space dilatation is empty to first
Between be worth dilatation request.
In this step, it should be noted that in embodiments of the present invention, when Spatial Residual value is less than or equal to default police
Announcement value, then illustrate insufficient space, needs dilatation.Now calculate the first spatial value after dilatation.
First spatial value is obtained using the first formula, and the first formula is：A=a+m, wherein, A be the first spatial value, a
For the current spatial value of the disk, m is default dilatation value.
For example, the current spatial value of the disk is 20G, and the default dilatation value of each dilatation is 30G, then the first spatial value
For 20+30=50G.
Now send the dilatation request that the disk space after dilatation reaches the first spatial value.
In addition, after dilatation request is sent, the dilatation mark bit variable for arranging the disk space is True, shows the magnetic
Disk has been sent from dilatation request.
S13, acquisition space of the disk in preset time period do not complete the confirmation of expansion, send the magnetic
The dilatation request of disk space dilatation to second space value.
In this step, it should be noted that in embodiments of the present invention, during by timer, in preset time period
Interior, the size for detecting disk space is not up to the first spatial value, then illustrate that disk space does not complete dilatation.
Now, the dilatation mark bit variable of the disk space is reacquired, determines that dilatation mark bit variable is True, said
The bright disk has been transmitted across dilatation request, need to again send dilatation request.
Because in preset time period, system can also use substantial amounts of memory space, i.e. space use value to send change.Cause
This, needs recalculate this for disk space dilatation how many spatial values.
After recalculating, disk space need to reach second space value.The second space value is obtained using the second formula, the
Two formula are：B=A+n × [d/n], wherein, B is second space value, and A is the first spatial value, and n is preset reference correction value, and d is
Spatial Residual value, [d/n] is to round.For example：[190/200]=0, [421/200]=2.
If the first spatial value is 20G, preset reference correction value is 2G, and Spatial Residual value is current spatial value 10G- space
Use value 6.5G=3.5G, [3.5/2]=1.Therefore, second space value is 20G+2 × 1=22G.
The disk space expansion method that the embodiment of the present invention 1 is provided, by the non-dilatation of disk space and in Spatial Residual
When value is not more than preset alert value, sends and ask the dilatation of the disk space dilatation to the first spatial value, and when default
Between in section the space of the disk do not complete when expanding, sending please by the dilatation of the disk space dilatation to second space value
Ask, so as to effectively reduce system resource, more accurately calculate the dilatation size for resending dilatation request, realize more preferably monitoring
The disk demand of system.
Fig. 2 shows that the embodiment of the present invention 2 provides a kind of disk space flash chamber, including acquisition module 21, first
The sending module 23 of module 22 and second is sent, wherein：
Acquisition module 21, the confirmation of the non-dilatation in the space for obtaining disk obtains the Spatial Residual of the disk
Value；
First sending module 22, determines that the Spatial Residual value is not more than preset alert value, sends the disk space
The dilatation request of dilatation to the first spatial value；
Second sending module 23, obtains the confirmation that the space of the disk in preset time period does not complete expansion,
Send and ask the dilatation of the disk space dilatation to second space value.
In disk space dilation process, when program is run, acquisition module 21 obtains the confirmation of the non-dilatation in space of disk
Information, obtains the Spatial Residual value of the disk, and Spatial Residual value is sent to into the first sending module.First sending module 22
Determine that Spatial Residual value is not more than preset alert value, send the dilatation request that disk space after dilatation reaches the first spatial value.Expand
After the Preset Time of appearance request terminates, the second sending module 2 obtains the space of the disk in preset time period and does not complete and expands
The confirmation filled, sends the dilatation request that disk space after dilatation reaches second space value.
A kind of specific work process of disk space flash chamber, may be referred to above-mentioned magnetic in the embodiment of the present invention 2
Content described by disk space expansion method, this is no longer going to repeat them.
It should be noted that can be by hardware processor (hardware processor) come real in the embodiment of the present invention
