In use can there is a large amount of disk remaining spaces for prior art, the problem of operation disk resource waste, first adjusts to the sorting technique of different types of data file in embodiments of the present invention, is divided three classes generally:
There is the data file of planning can only use the space of oneself for Spatial Dimension, the space of other types data file can not be used, this class data file belongs to fixed disk spatial class data file, and this class data file only needs the disk space of a distribution fixed size.
In addition, other types data file is when system still has disk remaining space, whole disk remaining space can be shared, wherein comprise the remaining disk space of fixed disk spatial class data file, this class data file comprises time-constrain class data file and ratio constraint class data file, wherein time-constrain class data file is the storage period specifying that it can store, such as specify its number of days that can store, the number of days that also can be able to store according to it in disk is converted into certain disk space, and for it allocates such disk space in advance in disk, but, when not reaching above-mentioned storage number of days, if this class data file has been filled with pre-assigned disk space, it can be stored into other disk remaining spaces in disk, or when other types data file needs, other types data file also can use the disk space for this class data file divides.Ratio constraint class data file is by the ratio of setting this type data file in disk space, distribute the different planning value of ratio constraint class data file in disk space, and when also having disk remaining space outside disk space removing retention disk space, disk remaining space still can store to ratio constraint class data file in the proportional distribution of setting in advance.
Give the data file of three types in the present embodiment, i.e. fixed disk spatial class data file, time-constrain class data file and ratio constraint class data file.But fixed disk spatial class data file can not be comprised and only time constraint class data file and ratio constraint class data file in some other application of the present invention, will not limit herein.
In embodiments of the present invention for ensureing the normal operation of operating system, can also retain certain disk space for operating system, this retention disk space can be the first threshold in the embodiment of the present invention.That is, when disk remaining space is less than the size in above-mentioned retention disk space, the mobile equilibrium disposal route of the disk space provided in the embodiment of the present invention and device, and disk system starts to clear up time-constrain class data file and ratio constraint class data file.Remove outside above-mentioned retention disk space, first can mark the space of fixed disk spatial class data file, last remaining allocation of space is to time-constrain class data file and ratio constraint class data file, ratio constraint class data file carries out disk space distribution according to a certain percentage, can avoid like this, when disk expansion capacity, resetting the planning value of Various types of data file.
Fig. 1 is the structural representation that in the embodiment of the present invention, disk divides, as shown in Figure 1, when the gross space of this disk is 100G, wherein retention disk space, namely the disk space amount taken when operating system is normally run in disk is 5G, category-A type data file is fixed disk spatial class data file, distribute 2G, category-B type data file is fixed disk spatial class data file, distribute 10G, C type data file is time-constrain class data file, plan that storage time is 3 days, be converted to disk space and be about 3G, D type data file, E type data file and F type data file are ratio constraint class data file, wherein D type data file distributes 10G, E type data file distributes 20G, F type data file distributes 50G.When disk space expands to 200G, prior art needs to reset data file planning value.And in the present invention, ratio constraint class data file will distribute disk space under a proportional relationship automatically, that is, D type data file can be automatically set as 22.5G, E type data file according to ratio and can be automatically set as 45G, F type data file according to ratio and can be automatically set as 112.5G according to ratio.
Based on the planing method of above-mentioned data file sorting technique and disk space, the embodiment of the present invention provides a kind of mobile equilibrium disposal route of disk space, Fig. 2 is the schematic flow sheet of the mobile equilibrium disposal route of disk space in the embodiment of the present invention, as shown in Figure 2, comprises following step:
Step 101, the disk remaining space amount obtained in disk;
Step 102, when disk remaining space amount in described disk is less than default first threshold, select the data file of exceeding the time limit in erasing time constraint class data file, and/or the data file generated the earliest is deleted from the higher class data file of utilization rate between ratio constraint class data file hollow, here space utilization rate refers to the ratio of the actual disk space taken of a class data file and the disk space distributed for this class data file, described time-constrain class data file and described ratio constraint class data file are can the data file of shared disk remaining space, described first threshold can be retention disk space,
When step 103, disk remaining space amount in described disk reach default Second Threshold, stop deleting data file.
In the above embodiment of the present invention, wherein time-constrain class data file and described ratio constraint class data file are can the data file of shared disk remaining space, and the disk remaining space amount only in described disk is when being less than default first threshold, just startup data file is deleted, the storage capacity of disk can be given full play to, avoid a large amount of disks idle, improve disk resource utilization factor.
The mobile equilibrium disposal route that the embodiment of the present invention provides, when comprising fixed disk spatial class data file, can also comprise following step:
When the disk space that fixed disk spatial class data file takies reaches pre-assigned disk space, delete the data file generated the earliest in fixed disk spatial class data file, until the disk space that fixed disk spatial class data file takies is less than pre-assigned disk space.
The mobile equilibrium disposal route that the above embodiment of the present invention provides, wherein select erasing time to retrain in class data file the data file of exceeding the time limit in step 102, and/or from the higher class data file of utilization rate between ratio constraint class data file hollow, delete the data file generated the earliest be specifically as follows:
The data file of exceeding the time limit in prioritizing selection erasing time constraint class data file, after formerly selecting the data file of exceeding the time limit in erasing time constraint class data file, if the disk remaining space amount of further judgement in disk does not reach default Second Threshold, then retrain the class data file that between class data file hollow, utilization rate is higher from ratio and delete the data file generated the earliest, until the disk remaining space amount in described disk reaches default Second Threshold, clear up from high to low according to space utilization rate like this, can ensure that the ratio of the ratio that these data files take up room and planning is consistent.
Further, in the above embodiment of the present invention, first threshold wherein can for the disk space amount taken when operating system in described disk is normally run, also can be when in above-mentioned disk, operating system is normally run on the basis of the disk space amount taken, increase certain safety value, namely increase the disk space of several G;
When being fixed disk spatial class data file distribution disk space in described disk, described Second Threshold is the disk space amount taken when operating system is normally run in described disk, is the disk space amount sum that fixed disk spatial class data file is distributed in described disk.

As shown in Figure 3, the mobile equilibrium disposal route of this disk space comprises the steps:
Step 201, first obtains the disk remaining space amount in disk;
Step 202, compares disk remaining space amount and the first threshold preset, if disk remaining space amount is less than first threshold, then carry out step 203, starts cleaning; If disk remaining space amount is greater than first threshold, then jump directly to step 207, all types of data files stored are not deleted in disk, it should be noted that first threshold can be retention disk space;
Step 203, when disk remaining space amount is less than first threshold, the data file of exceeding the time limit in prioritizing selection time-constrain class data file is deleted;
The conversion counting to disk space to the conversion of number of days or sky due to disk space estimates, so likely occur that disk space has reached planning value, and store number of days not to storage period, likely occur that storing number of days first reaches planning value, but storage space does not also arrive the situation of planning value yet.Now pay the utmost attention to default time planning value, such as, in Fig. 1, planning C type data file storage period is three days, three days storage periods were scaled disk space greatly about about the space of 3G, if save C type data file to store two days, disk space shared by it reaches 4G, does not now delete C type data file, but the data file exceeding planning value 3G is stored in other disk remaining spaces; If C type data file stores four days, but its disk space taken only has 2G, do not exceed the 3G that planning value converts, now, due to its storage period should be paid the utmost attention to for time-constrain class data file, although so institute takes up space do not reach planning value, still need to delete the data file more than three day time limit, it should be noted that and select to delete data file the earliest herein.
Step 204, after the data file of exceeding the time limit in time-constrain class data file is deleted, disk remaining space and Second Threshold are compared, when disk remaining space reaches default Second Threshold, then jump directly to step 207, stop the cleaning to all types of data files stored in disk; When disk remaining space does not reach default Second Threshold, then carry out step 205, start comparative example constraint class data file and clear up;
Step 205, when disk remaining space does not reach default Second Threshold, starts comparative example constraint class data file and clears up.Retrain the class data file that between class data file hollow, utilization rate is higher from ratio and delete the data file generated the earliest, like this because the algorithm deleting data file is for foundation with space utilization rate height, the result of so clearing up still can ensure that the use of several data file to space of ratio constraint class data file is proportional consistent with the ratio of planning, thus reaches mobile equilibrium;
Step 206, compares disk remaining space and Second Threshold, when disk remaining space reaches Second Threshold, carry out step 207, namely stops removing; If disk remaining space does not reach Second Threshold, then continue rebound step 205, continue comparative example constraint class data file carry out clearing up until, disk remaining space reaches Second Threshold.
Fig. 4 is the schematic flow sheet of fixed disk spatial class data file method for cleaning, is further described fixed disk spatial class data file method for cleaning below in conjunction with Fig. 4.
As shown in Figure 4, this fixed disk spatial class data file method for cleaning step is as follows:
Step 301, first obtains the disk space amount that in disk, fixed disk spatial class data file takies;
Step 302, compares the disk space amount taken with the fixed disk spatial class data file obtained and pre-assigned disk space amount, if do not exceed default planning value, does not then clear up; If exceeded the planning value preset, then carry out step 303, fixed disk spatial class data file has been cleared up;
Step 303, deletes the data file generated the earliest in fixed disk spatial class data file;
Step 304, again the disk space amount that now fixed disk spatial class data file takies is compared with the space disk planning value preset, if now fixed disk spatial class data file memory space is still greater than planning value, then rebound step 303, proceed cleaning; If now fixed disk spatial class data file memory space has been less than planning value, then arrive step 305, terminate cleaning.
The mobile equilibrium disposal route of the disk space that the embodiment of the present invention provides, due to removing fixed disk spatial class data file, other types data file is when system still has disk remaining space, whole disk remaining space can be shared, wherein comprise the remaining disk space of fixed disk spatial class data file, the data file being so equivalent to these types can shared disk remaining space, disk remaining space can be utilized to greatest extent when the data file of some type does not generate, avoid waste.The design in retention disk space allows system can not produce fault because of Insufficient disk space all the time, improves reliability.The method of the planning disk space of ratio constraint class data file is pro-rata, and therefore the planning value of disk is revised in the lifting of disk specification without secondary.Because deletion data file algorithm is with space utilization rate height for foundation, the result of so clearing up still can ensure that ratio constraint class data file is identical with the ratio of planning to the usage ratio in space, thus reaches mobile equilibrium.
