Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Fig. 1 shows one embodiment of the invention and provides a kind of based on the hard disk hanging method under embedded system, comprising:
New hard disk after S1, systems axiol-ogy to interpolation;
S2, system obtain the average utilization of current all CPU, this average utilization Y=(y1+y2+ ... + yn)/n, wherein y1, y2 ... yn is the utilization factor of each CPU respectively, and n is the CPU number in system.
S3, system obtain the usage ratio X of current all hard-disk capacities.
According to described average utilization and described usage ratio, S4, system judge whether described new hard disk carries out carry.
Further, the formula whether carrying out foundation in the judgement of carry at described new hard disk is: X+ (1-Y)/n > ε, wherein, X is the usage ratio of current all hard-disk capacities, Y is the average utilization of current all CPU, n is the number of CPU in system, and ε is predetermined threshold value coefficient.According to above-mentioned acquisition judged result be: if X+ (1-Y)/n > ε sets up, then carry is carried out to new hard disk; Otherwise new hard disk is vacant.
System carries out carry according to judged result to the new hard disk recognized.Carry out in carry process to new hard disk, system can complete the format to new hard disk according to various instruction automatically, and subregion, sets up the actions such as catalogue, to complete carry work.
For above-mentioned method step, with specific embodiment, this is explained.Utilization factor as there is four CPU, each CPU in system is respectively 10%, 50%, 80% and 20%.So average utilization Y=(10%+50%+80%+20%)/4=40%.The usage ratio X=80% of current all hard-disk capacities.So hard disk carry judgment formula: X+ (1-Y)/n=0.8+ (1-0.4)/4=0.95.Predetermined threshold value coefficient ε=0.8 under normal circumstances, then 0.95 > 0.8.At this moment, system just start to identification and not yet the new hard disk of carry carry out carry.As also in said system, the usage ratio X=60% of current all hard-disk capacities.So hard disk carry judgment formula: X+ (1-Y)/n=0.6+ (1-0.4)/4=0.75.Predetermined threshold value coefficient ε=0.8 under normal circumstances, then 0.75 < 0.8.At this moment, system does not carry out carry to the new hard disk recognized.
Explain explanation further, this method is being carried out in carry process to the new hard disk recognized, and also needs to select Format Type to new hard disk.Its step comprises:
System can judge to obtain the Format Type of current all hard disks and add up the number of each Format Type.
If the statistics number of certain Format Type is maximum, then belonging to new hard disk, Format Type is given tacit consent to this Format Type of selection.
If the statistics number that there is two or more Format Type is identical, then calculate hard disk total volume size belonging to often kind of Format Type, new hard disk form type is Format Type belonging to the maximum hard disk of total volume.
For the selection of the Format Type of the new hard disk of above-mentioned carry, be described by specific embodiment.If there are three hard disks in system, wherein two is ext4 form, and one is ext3 form, then the Format Type of carry hard disk just selects ext4 form.If there are four hard disks in system, two is ext4 form, and total volume size is 100G; Two is ext3 form, and total volume size is 200G.Then the Format Type of carry hard disk just selects ext3 form.
Explain explanation further again: this method is being carried out in carry process to the new hard disk recognized, also need to set up hard disk catalogue to new hard disk.System can set up hard disk catalogue successively according to the carry order of new hard disk.Such as it sets up catalogue/tmpN, and wherein N increases along with the number of carry hard disk and increases, and such as adds the tenth piece of new hard disk, then sets up catalogue/tmp10, and by the hard disk carry that just formatd in newly-built catalogue.
If system continues content to write in carry hard disk, when under present hard discs catalogue, carry hard disk remaining capacity is less than or equal to predetermined threshold value, system is carry hard disk continuation write to be used under automatically switching to next hard disk catalogue.As present hard discs is mounted to/tmp8, when hard drive space residual capacity is 10%, then system automatically switches to/tmp9, continues to write on the hard disk under/tmp9.
This method after system identification adds to new hard disk, can not carry out format carry to this hard disk immediately.First system can be passed through to judge to determine whether to need new hard disk carry according to the average utilization of current all CPU and current all hard-disk capacity usage ratios.When the new hard disk of needs carry, then system automatically starts new formatting hard disk according to instruction, sets up a series of carry actions such as catalogue.Accomplish to carry out carry without the need to manual operation, the system in prior art that solves can identify hard disc apparatus, but non-serviceable problem.
