Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiments of the invention provide a kind of data managing method, applied in file system, in the present invention, file system
The memory space of system includes m block group, wherein, m is the integer more than 0, shown in reference picture 1, is comprised the following steps：
101st, judge whether the space hold amount of n-th piece of group reaches default threshold value in m block group.
Wherein, n is the integer more than 0 less than m.
If the 102, the space hold amount of n-th piece of group reaches default threshold value, migration specific item is obtained in n-th piece of group
Record.
If the space hold amount of n-th piece of group reaches default threshold value, illustrate that the space of n-th piece of group writes full, it is impossible to write again
Enter new data, in order to ensure data and metadata under same subdirectory in same piece of group, it is necessary to will selection one or
Multiple subdirectories are moved in next piece of group as migration subdirectory, so so that the subdirectory stored in each block group
Data and metadata complete under the catalogue are contained, file place directly can be determined by directory name when accessing file
Block group, improves access efficiency, and if having file corruption in a block group, do not interfere with other block groups, improve file
The performance of system.
103rd, the data and metadata that migrate in subdirectory are moved in (n+1)th piece of group.
Wherein, data include the particular content of file in file system.Catalogue, document creation where metadata includes file
The information such as time, filename, file size, file storage location.
The data managing method that embodiments of the invention are provided, applied to file system, by judging the in m block group
Whether the space hold amount of n block groups reaches default threshold value, if the space hold amount of n-th piece of group reaches default threshold value,
Migration subdirectory is obtained in n-th piece of group, and the data and metadata that migrate in subdirectory are moved in (n+1)th piece of group, is carried
The high performance of file system.
Based on the corresponding embodiments of Fig. 1, another embodiment of the present invention provides a kind of data managing method, applied to file
System, shown in reference picture 2, specifically includes following steps：
201st, the memory space of file system is divided into m block group.
It is specific optional, the memory space of file system is divided into m block group of capacity identical；
Or, the maximum and minimum value of a block pool-size are set, dynamic tune is done according to the size of catalogue in use
It is whole.
The 202nd, data and metadata initial in file system are stored in the 1st piece of group in m block group.
203rd, judge whether the space hold amount of the 1st piece of group reaches default threshold value.
If the 204, the space hold amount of the 1st piece of group reaches default threshold value, migration specific item is obtained in the 1st piece of group
Record.
It is specific optional, when the space hold amount of the 1st piece of group reaches default threshold value, in the superblock of file system
The space hold information of subdirectory is inquired about, data capacity is expanded to most fast subdirectory as migration subdirectory.Wherein, data are held
Amount expands most refers under subdirectory that the data capacity rate of rise that stores is most fast soon, and file system superblock includes file system specific item
The information such as record, file system gross space, the space used, total files.
205th, the data and metadata that migrate in subdirectory are moved in the 2nd piece of group.
Specific optional, the metadata in migration subdirectory reads the corresponding number of metadata in migration subdirectory
According to, and the corresponding data of metadata in the metadata migrated in subdirectory and migration subdirectory are moved in the 2nd piece of group.
Repeat step 203-205, until m block group of file system is all distributed.So it is achieved that file system
Data and metadata in system are divided into block group and are managed, the access and backup of convenience file.
The data managing method that embodiments of the invention are provided, applied to file system, by judging the in m block group
Whether the space hold amount of n block groups reaches default threshold value, if the space hold amount of n-th piece of group reaches default threshold value,
Migration subdirectory is obtained in n-th piece of group, and the data and metadata that migrate in subdirectory are moved in (n+1)th piece of group, is carried
The high performance of file system.
Based on the corresponding embodiments of Fig. 1 and Fig. 2, embodiments of the invention provide a kind of file access method, the institute of reference picture 3
Show, comprise the following steps：
301st, file access request is received.
Specifically, this document access request includes filename and directory name.Because to find file according to the directory name
Place block group, so the directory name very little, can determine block group where unique block group, that is, file according to the directory name.
302nd, the block group according to where directory name determines catalogue.
Specifically, according to directory name in the file system search catalogue, if searching the catalogue, it is determined that the catalogue institute
In block group, if do not found, error reporting is returned to.
If block group where catalogue the 303, is found, according to filename lookup file metadata.
Specifically, after block group where determining catalogue, block group is according to filename lookup file metadata where catalogue.
After step 302, in addition to：
If the 304, not finding block group where catalogue, error message is returned.
After step 303, in addition to：
If the 305, finding file metadata, the block group locating file data according to where metadata in catalogue.
After step 303, in addition to：
If the 306, not finding file metadata, error message is returned.
On the basis of with block group management file system, place block group can directly be determined according to directory name by accessing file,
Only need to search the block group and can be achieved with accessing, it is not necessary to the locating file in whole file system, improve and access file
Efficiency.
The data managing method that embodiments of the invention are provided, applied to file system, by judging the in m block group
Whether the space hold amount of n block groups reaches default threshold value, if the space hold amount of n-th piece of group reaches default threshold value,
Migration subdirectory is obtained in n-th piece of group, and the data and metadata that migrate in subdirectory are moved in (n+1)th piece of group, is carried
The high performance of file system.
Based on the corresponding embodiments of Fig. 1 and Fig. 2, embodiments of the invention provide a kind of file backup method, the institute of reference picture 4
Show, comprise the following steps：
401st, the block group according to where predetermined directory name searches the predetermined directory in the memory space of file system.
When user needs one catalogue of backup, the block group according to where predetermined directory name searches the catalogue is specific optional,
When directory name is very big, data and metadata under the catalogue are stored in multiple pieces of groups, when directory name very little, under the catalogue
Data and metadata be stored in a block group.
If the 402, finding block group where predetermined directory, metadata all under predetermined directory and data Cun Chudao are preset
Backup space.
It is specific optional, can also be default standby by all metadata in block group where the catalogue and data Cun Chudao
Part space.
After step 401, in addition to：
If the 403, not finding block group where predetermined directory, error message is returned.
Because being backed up with block group, when file system breaks down, as long as recovering error block group, it becomes possible to extensive
It is multiple normal, improve the performance of file system.
