Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of disk failure processing method, reduces in disk failure and accounts for because of data reconstruction
System resource does not influence the normal operation of upper-layer service.
Referring to Fig. 1, a kind of flow chart of disk failure processing method shown according to an exemplary embodiment, such as Fig. 1 institute
Show, comprising:
S101: when receiving the error code that target sector returns in target disk, according to the data of the target sector
Create new sector；
In specific implementation, when the object of the read-write requests of upper layer application falls in failure sector (i.e. this step of target disk
Target sector in rapid) when, which can return to error code, and no longer simple collapse is exited at this time, but is entered and repaired
Mode, i.e., sector new according to the data creation of the target sector are used for normal response read-write requests, do not influence upper-layer service
It runs well.
In this step, the concrete mode of creation sector is not defined, those skilled in the art can be according to reality
Situation flexible choice is deleted or the mode of copy for example, can use to entangle.For data, disk can be using data copy
Mode guarantees to remain to continue to use after certain data degradations, and copy loses the data for only needing to copy to lose, and does not lose
Data offer service can be provided, repair time is shorter.I.e. as a preferred embodiment, this step may include true
The redundancy magnetic disk of the fixed target disk, by the data copy of the corresponding sector in target sector described in the redundancy magnetic disk to institute
State new sector.
As another preferred embodiment, this step may include by correcting and eleting codes technology by the target sector
Data are restored to the new sector.It is exactly the data loss for the fault-tolerant in addition to copy is there are also another way of data
It calculates, i.e. correcting and eleting codes technology.Compared with copy, the advantages of correcting and eleting codes, is to save memory space., disadvantage is there is calculating
Expense and reparation needs certain time, as long as and copy loses the data that copy to lose, the data that do not lose can be after
Continuous offer service.
S102: database is added to by the target sector renamed as failure filename, and by the failure filename
In；Wherein, the sector of the entitled failure filename stops response read-write requests；
It should be noted that this step and previous step have no specific ordinal relation, it can successively executing can also be with
It is performed simultaneously.In this step, by target sector renamed as failure filename, the sector of the entitled failure filename stops
Read-write requests are responded, but the new sector that the read-write requests are transferred to previous step creation is responded.
In this step, failure filename can be stored in database profession in the form of tables of data, naturally it is also possible to it
He stores form, herein without specifically limiting.Failure text when target sector is failure sector, after being renamed
Part name is added in database.
S103: when the failure filename quantity in the database is more than preset value, triggering OSD process collapse.
In specific implementation, when the quantity of failure sector is more than preset value, triggering OSD process collapse is exited, and to magnetic
Disk is positioned.The preset value is that can match parameter, and those skilled in the art can be adjusted according to disk size size.
On the basis of the above embodiments, as a preferred implementation manner, further include: the failure in the database
When filename quantity is more than preset value, warning information is issued to management terminal according to the disc information of the target disk.
It in specific implementation, can also be to management terminal when the failure filename quantity in database is more than preset value
Issue warning information.The present embodiment does not limit the form of warning information specifically, such as can pass through short message and mail
Mode notifies operation maintenance personnel, so that operation maintenance personnel is handled in time.
On the basis of the above embodiments, as a preferred implementation manner, further include: within a preset time to the mesh
All sectors for marking disk send test command, to return to error code when the sector failure.
In specific implementation, other than the EIO that the processing Real time request of the present embodiment introduction occurs, compare in traffic pressure
In small preset time (such as at night), the object that can also store to rear end is scanned, when inconsistent object is arrived in scanning,
I.e. some object falls in failure sector bottom and returns to EIO, is isolated using above-mentioned same abnormality eliminating method, is subtracted as far as possible
Occur influence of the EIO caused by Real time request when repairing damage object to upper-layer service less.
Disk failure processing method provided by the embodiments of the present application, after generating the target sector of failure, for target fan
The new sector of the data creation in area is used for normal response read-write requests, does not influence the normal operation of upper-layer service.Simultaneously by the mesh
Sector renamed as failure filename is marked, the sector of the entitled failure filename stops response read-write requests, except failure is fanned
Disk can continue to use outside area, will not cause data reconstruction, therefore will not occupying system resources.
The embodiment of the present application discloses a kind of disk failure processing method, and relative to a upper embodiment, the present embodiment is to skill
Art scheme has made further instruction and optimization.It is specific:
Referring to fig. 2, the flow chart of another disk failure processing method shown according to an exemplary embodiment, such as Fig. 2
It is shown, comprising:
S201: when receiving the error code that target sector in target disk returns, by correcting and eleting codes technology by the mesh
The data of mark sector are restored to the new sector.
S202: database is added to by the target sector renamed as failure filename, and by the failure filename
In；Wherein, the sector of the entitled failure filename stops response read-write requests；
S203: when the failure filename quantity in the database is more than preset value, triggering OSD process collapse.
A kind of disk failure processing system provided by the embodiments of the present application is introduced below, a kind of magnetic described below
