Embodiment
The embodiment of the disclosure is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
In the embodiment of the present disclosure, storage device can be any data-storable equipment, such as, HDD (Hard
Disk Drive, hard disk), SSD (Solid State Drives, solid state hard disc), (HybridHard Disk, mixing are hard by HHD
Disk), etc..
In the embodiment of the present disclosure, computer can be the computer that arbitrary disposition has multiple storage devices, such as, it is configured with
8 pieces of HDD server, etc..In one embodiment, computer can be appointing in distributed file system (such as HDFS)
One Datanode nodes.
Fig. 1 is referred to, Fig. 1 is a kind of flow chart of storage device detection method according to an exemplary embodiment,
As shown in figure 1, the storage device detection method can apply in computer, comprise the following steps.
Step S11：Determine multiple storage devices to be detected that computer includes.
Step S12：Multiple storage devices are detected, to determine in multiple storage devices by multiple thread parallels
Each storage device whether can use.
Multiple storage devices to be detected can be the whole storage devices configured on computer, or can also be wherein
Part storage device, such as can set only the several storage devices of certain in computer are detected, then can only therefrom
Determine these storage devices to be detected.
In order to ensure the reliability of computer, in computer starting, the whole storages that can include to computer are set
It is standby to be detected, and then detect which storage device can use, which storage device is unavailable, and then determines that whole computer is deposited
The availability of the data of storage.For the detection mode for single storage device, the embodiment of the present disclosure is not construed as limiting, for example, can
To perform establishment file in storage device, read the operations such as file, deletion file.
In the embodiment of the present disclosure, the multiple storage devices detected to needs with can enabling multiple thread parallels are carried out
Detection, improves the detection speed of storage device, while also improve the toggle speed of computer.
Optionally, it is how many for starting the number of threads for being used to detect storage device, the embodiment of the present disclosure is not construed as limiting.
The smaller value in the quantity of multiple storage devices and the maximum thread that computer allows can be first determined, then passes through smaller value
The thread of respective amount, concurrently multiple storage devices are detected.
For example, the storage device to be detected has 10, the maximum thread amount that computer system enables while permission is 8
It is individual, then 8 threads can be enabled simultaneously concurrently to be detected to 10 storage devices.Such as that to be detected deposits
Storage equipment has 10, and the maximum thread amount that computer system enables while permission is 12, then can enable 10 simultaneously
Individual thread concurrently detects to 10 storage devices.Such as the storage device to be detected has 10, department of computer science
The maximum thread amount that system enables while permission is 10, then can enable 10 threads simultaneously and come to 10 storage devices
Concurrently detected.
By with upper type, can as often as possible enable thread and carry out parallel detection storage device, can save as much as possible
The detection time of storage device, lift the toggle speed of computer.
It will be illustrated below to detecting multiple possible implementations of storage device by multiple thread parallels.
In order to realize the parallel detection of storage device, when starting detection, four lists can be created：List is completed, is used
To deposit the storage device completed after testing；List is carrying out, for depositing the storage device detected by thread；Can
With storage device list, completed for depositing detection, and testing result is available storage device；Unavailable storage device row
Table, completed for depositing detection, and testing result is disabled storage device.
That is, in detection process, if a thread starts to detect a storage device, then can be with
The storage device is added to and is carrying out in list, so, other threads can know that the storage device is detected.
The storage device, can be added to and complete in list by a storage device if a thread detection is over, and according to detection
As a result the storage device is added in available storage device list or unavailable storage device list, so, other threads
The result that the storage device has been completed to detect and detected can be known.
Optionally, for any thread in multiple threads, the Schilling thread is random from multiple storage devices to determine one
Storage device, it is then determined that whether the storage facilities has been completed to detect, it can be divided into when the storage device does not complete detection
Following two situations：If the storage device is detected by another thread, the thread can be made to redefine a storage device；
If the storage device is not detected, the thread can be made to detect the storage device.
After starting detection, multiple threads start simultaneously, and concurrently the multiple storage devices to be detected are detected, multiple
Each thread in thread can perform the step of determining a storage device from multiple storage devices at random, then for it
In a thread for, it is determined that storage device be possible to have completed detection (in list is completed), or may also not have
There is completion to detect.For no storage device (not in list is completed) for completing detection, may there are two kinds of situations, the first feelings
Condition, the storage device is by the detection of another storage device (in list is carrying out), then before thread can return
Object, that is, go to determine a storage device again, certainly, completion or whole inspection are all detected if all of storage device
Survey process is over, and the thread can be operated with termination detection；Second of situation, the storage device are not detected among (not just
In list is performed), then the thread can be detected directly to the storage device., can be preferably by with upper type
Realize and detect multiple storage devices using multiple thread parallels, and then save the detection time of storage device, lift storage device
Detection speed.
In one embodiment, the above does not complete the situation progress of detection to the storage device that a certain thread determines at random
Explanation, then if the storage device that a certain thread is determined at random has completed detection (in list is completed), then this
Thread can be returned directly, that is, not handle the storage device, go to determine a storage device again, if likewise, institute
Some storage devices have all detected completion or whole detection process is over, and the thread can be operated with termination detection.
In another embodiment, if the storage device that a certain thread is determined at random has completed detection and (completed to arrange
In table), the thread can also determine whether to again examine the storage device according to the detection case of the storage device
Survey, possible situation will be illustrated below.
Optionally, when the storage device has completed detection, it may further determine that the storage device is last and complete inspection
Whether it is more than the first preset duration to the duration interval at current time at the time of survey, if duration interval is default more than first
It is long, the thread can be made to be detected again to the storage device；If duration interval is not more than the first preset duration, Ke Yiling
The thread redefines a storage device.
First preset duration can be the duration set when computer dispatches from the factory, or can also be by user's sets itself
And the duration that can be modified as needed after setting.For example, the first preset duration can be set as 3 minutes, etc..This
In open embodiment, the temporal information that the moment is completed in detection can be retained by completing the storage device in list, so as to thread according to
Temporal information determines whether to detect it again.
One storage device is in the case where having completed detection, if apart from the last detection completion of the storage device
Time is longer, then during this period, the storage device has been likely to occur damage, therefore can be to the storage device again
Detected, now no matter last testing result is available or unavailable, can be detected again.And if distance
The time that the last detection of storage device is completed is shorter, then it is considered that the result of last detection is reliable, therefore can
That need not detect again.This way it is possible to avoid detection operation is repeatedly carried out in the short time, while set saving storage as far as possible
In the case of standby detection time, the reliability of testing result is improved, the testing result of storage device is more accurate.
Optionally, completed to detect in multiple storage devices, and one in any storage device in multiple storage devices
When being less than the first preset duration to the duration interval at current time at the time of secondary completion detection, it may be determined that multiple storage devices are complete
Into detection.
That is, all storage devices are included in available respectively all in list is completed also according to testing result
In storage device list and unavailable storage device list, also, to current time at the time of the completion detection of all storage devices
Duration be both less than the first preset duration, testing result can be returned to detection of end task, such as, computer is distributed text
A certain Datanode nodes in part system, then testing result can be returned to Namenode nodes.By such mode,
The detection speed of storage device can be improved, also ensures that the reliability of testing result, obtained testing result is more accurate.
Generally, thread can determine whether storage device can use when detecting storage device according to the situation of detection, than
If as detected, some storage device correctly establishment file or can not correctly read file, it may be determined that the storage device is not
It can use.Optionally, the embodiment of the present disclosure can also be up to when any storage device in detecting multiple storage devices is lasting
During to the second preset duration, determine that the storage device is unavailable.
Second preset duration can be the duration set when computer dispatches from the factory, or can also be by user's sets itself
And the duration that can be modified as needed after setting.For example, the second preset duration can be set as 20 seconds, etc..
If that is, a storage device detection time is long, the possibility that the storage device breaks down is larger,
So it is also assumed that the storage device is unavailable.In use, thread can be such as made when starting to detect storage device, note
Record starts the time of detection, then calculates the time of the current execution to be detected such as, is subtracted with the second preset duration of setting
The currently duration used in perform detection, and then obtain allowing the duration waited, implementing result can be obtained with block type, it is most long
Blocking time is the remaining duration for allowing to wait, overtime abnormal more than can then dish out, that is, determines that the storage device is unavailable,
The storage device is put into unavailable storage device list.By such mode, can avoid because of storage device self reason
Cause detection time long and influence whole detection speed, further increase storage device detection speed.
After completing detection, the storage performance of computer can be determined according to the testing result of all storage devices.Example
Such as, computer can be some Datanode node in HDFS, be configured with 20 storage devices, the maximum unavailable storage of setting
Number of devices is 10, then if the storage device more than 10 is unavailable in testing result, the Datanode can be made to save
Point starts failure；Or if if the quantity of unavailable storage device is no more than 10 in testing result, this can be made
Datanode nodes normally start, and can use storage device to Namenode node feeding backs.
