Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of hard disk hanging method, device, equipment and computer readable storage mediums, with reality
Now after pulling out the hard disk in storage system, good preparatory condition is provided for the grafting again of hard disk, ensures the success of hard disk
Carry improves the stability and robustness of storage system.
Referring to Fig. 1, a kind of hard disk hanging method provided in an embodiment of the present invention, including：
It whether there is the target directory of carry target hard disk in S101, detection target storage system；If so, executing
S102；If it is not, then executing S103；
Specifically, in carry hard disk, the case where carry fails is frequently encountered, the present embodiment is carried for two kinds of failure causes
The processing method of optimization is gone out.First, when needing grafting again after hard disk is pulled out, may due to previous hard disk OSD into
Cheng Wei discharges mount directory, and the hard disk carry of grafting again is caused to fail；Second, when previous hard disk is discharging carry mesh
When record, the hard disk of grafting can cause carry to fail due to can not find corresponding mount directory again.
The second equipment in the parent directory of S102, the first device number in the acquisition target directory and the target directory
Number, and execute S104；
In the present embodiment, for the first situation, by obtaining the first device number and target directory in target directory
Parent directory in the second device number show that target directory has been released, then if the first device number and the second device number are identical
Direct carry hard disk；If the first device number and the second device number differ, shows that target directory is not released, then need
The carry hard disk again after target directory release.
S103, the target directory is created, and executes S105；
In the present embodiment, for the second situation mesh is no longer waiting for by creating target directory come carry target hard disk
The release of heading record.
Whether S104, detection first device number and second device number are identical；If so, executing S105；If it is not,
Then execute S106；
S105, by the target hard disk carry to the target directory；
S106, judge whether current detection number is more than preset first threshold；If so, exiting flow；If it is not, then executing
S102。
In the present embodiment, can be to detect target directory by detecting the device number in target directory and its parent directory
It is no to be discharged by previous OSD processes；Meanwhile in order to reserve the sufficient end time to previous OSD processes, spy can be preset
The number of fixed detection device number then obtains the device number of the two again when detecting number not less than preset first threshold
And be detected, until when detection number is more than preset first threshold, just exit flow.Wherein it is possible to according to it is preset when
Between interval carry out repeat detection.
It should be noted that since the end of OSD processes needs period regular hour, and in nowadays ever-changing number
According to the epoch, each millisecond will all generate huge value.Therefore, it repeats grafting for the hard disk in storage system and excellent elder generation is provided
Certainly condition is indispensable.Meanwhile the reason of hard disk carry failure, is varied, the present embodiment is carried for both the above situation
Simple and convenient and enforceable technical solution has been supplied, the success rate of hard disk carry can be improved.
As it can be seen that a kind of hard disk hanging method provided in this embodiment, whether the method is deposited by detecting in storage system
In the catalogue of carry hard disk, when there are the first device numbers when catalogue, then obtained in the catalogue and described in storage system
The second device number in the parent directory of catalogue shows that the catalogue has been released if the first device number and the second device number are identical,
By the direct carry of the hard disk to the catalogue；If the first device number and the second device number differ, show the catalogue
It is not released, the hard disk described in carry again after the catalogue is released.Also it is hard disk thus, it is possible to ensure the successful carry of hard disk
It repeats grafting carry and good preparatory condition is provided；Meanwhile also improving the stability and robustness of storage system.
The embodiment of the invention discloses another hard disk hanging methods, and relative to a upper embodiment, the present embodiment is to technology
Scheme has made further instruction and optimization.
Referring to Fig. 2, another kind hard disk hanging method provided in an embodiment of the present invention, including：
It whether there is the target directory of carry target hard disk in S201, detection target storage system；If so, executing
S202；If it is not, then executing S203；
The second equipment in the parent directory of S202, the first device number in the acquisition target directory and the target directory
Number, and execute S204；
S203, the target directory is created, and executes S205；
Whether S204, detection first device number and second device number are identical；If so, executing S205；If it is not,
Then execute S206；
It should be noted that when target hard disk carry is completed, need to detect hard disk and whether succeeded carry, when detecting
When hard disk success carry, follow-up process is just carried out；When detecting the failed carry of hard disk, then carry target hard disk again, and
Carry success is detected whether again；So cycle exits flow until when beyond preset detection number.
After the success of hard disk carry, the file destination detected in target directory whether there is, storage in the file destination
The information such as the ID of the corresponding OSD of target hard disk.Wherein, the ID of OSD be fixed when creating OSD existing for, be it is artificial controllable,
This is different from the ID of OSD processes, and the ID of OSD processes is that operating system is randomly assigned, and is artificial uncontrollable.Wherein, described
File destination is the associated profile after the success of hard disk carry, such as：Whoami files etc.；If the mesh in the target directory
It marks file to exist, then shows that corresponding OSD processes can be started；If after repeating detection file destination, in the target directory
File destination is still not present and has been more than preset judgement number, just exits flow.
S205, by the target hard disk carry to the target directory, and execute S207；
S206, judge whether current detection number is more than preset first threshold；If so, exiting flow；If it is not, then executing
S202。
Whether carry is successful for S207, the detection target hard disk；If so, executing S208；If it is not, then executing S205；
File destination in S208, detection target directory whether there is；If so, executing S210；If it is not, then executing
S211；
S209, judge whether current detection number is more than preset second threshold；If so, exiting flow；If it is not, then holding
Row S205；
S210, start the corresponding OSD processes of the target hard disk；
S211, judge whether current detection number is more than preset third threshold value；If so, exiting flow；If it is not, then executing
S208。
In the present embodiment, in order to reserve enough mounting times to the carry of target hard disk, detection can be repeated
Whether device number, detection hard disk carry success and detect whether the execution step there are file destination, respectively each detection step
Corresponding detection threshold value is set suddenly, when detecting number more than preset threshold value, exits flow；When detection number be less than it is default
Threshold value when, then repeat detect.
It should be noted that when executing arbitrary repetition detecting step provided in this embodiment, between can presetting accordingly
Every the time.Such as：In detection device, if the device number of detection target directory and its parent directory differs, interval is default
Time after, again obtain target directory and its parent directory device number, judge again the two it is whether identical.Wherein, technology people
Member can preset different time intervals according to actual demand.Accordingly for detection hard disk whether carry success and detection be
No there are the repetition of file destination detections, can also preset the time interval for meeting actual demand, the present embodiment is no longer superfluous to this
It states.
Start the corresponding OSD processes of the target hard disk it should be noted that described, including：It is opened according to input by user
The instruction for moving the OSD processes starts the OSD processes, and cancels and the OSD processes is waited for execute the delay completed.
Specifically, since the startup of OSD processes is than relatively time-consuming, when multiple hard disks carry simultaneously, the same lock can be shared
It is unlocked startup, and is serial operation；Due to time restriction, a part of hard disk time-out when waiting for unlock can be caused, it can not
Normal carry also can not normally start OSD processes.Therefore, in order to reduce time loss when OSD process initiations, when user inputs
When starting the instruction of OSD processes, start corresponding OSD processes immediately, and cancels and the OSD processes is waited for execute the delay completed.
Such as：When the grafting simultaneously of multiple hard disks within the storage system when, it is assumed that these hard disks have succeeded carry, then using
Family starts the corresponding OSD processes of these hard disks by enabled instruction is inputted, at this point, after first OSD process initiation, storage
System front end is no longer waiting for the process and executes the return message completed, and starts second OSD process immediately, other and so on.
After these OSD processes are started, it is made to operate in storage system rear end.Thus the time of OSD process initiations has been saved.If depositing
In the OSD processes for starting failure, technical staff can check corresponding hard disk and catalogue file, to find to start the original of failure
Cause, timely processing.
As it can be seen that another kind hard disk hanging method provided in this embodiment, the method by detect in storage system whether
There are the catalogue of carry hard disk, when there are when the catalogue, then obtaining the first device number in the catalogue and institute in storage system
The second device number in the parent directory of catalogue is stated, if the first device number and the second device number are identical, shows that the catalogue is released
It puts, by the direct carry of the hard disk to the catalogue；If the first device number and the second device number differ, show the mesh
Record is not released, the hard disk described in carry again after the catalogue is released.Also it is hard disk thus, it is possible to ensure the successful carry of hard disk
Repetition grafting carry good preparatory condition is provided.
Meanwhile the present embodiment additionally provides the method for judging whether to start the corresponding OSD processes of target hard disk, passes through
Judge that the specific file in catalogue whether there is to differentiate whether the corresponding OSD processes of hard disk can normally start；When in catalogue
Specific file in the presence of, then show that the corresponding OSD processes of the target hard disk can start；Specific file in the catalogue
In the absence of, then described the step of judging in the target directory with the presence or absence of file destination is repeated, until more than default
The presence for judging number or detecting file destination.It is possible thereby to carry out the startup of the corresponding OSD processes of hard disk in time；Work as inspection
When not detecting corresponding file destination, technical staff can detect corresponding configuration file and interface, to improve storage system
Stability and robustness.
Based on above-mentioned any embodiment, it should be noted that it is described by the target hard disk carry to the target directory,
Including：
Judge that the corresponding UUID of the target hard disk whether there is；
If so, record the corresponding UUID of the target hard disk, and execute it is described by the target hard disk carry to described
The step of target directory.
Specifically, UUID (Universally Unique Identifier) is Universally Unique Identifier, the mesh of UUID
, it is all elements in allowing distributed memory system, there can be unique identification information, without penetrating central control terminal
To do the specified of identification information.Thus, which everyone could set up the UUID not conflicted with other people.In such situation
Under, just it is not required to consider title replication problem when Database.Therefore, do not allow that there are identical UUID in storage system.
It, may be due to the corresponding UUID of the hard disk when needing grafting again after hard disk is pulled out but in hard disk carry
It is not cleared up away from kernel, when by the hard disk again grafting, storage system can report an error because UUID is repeated, and then cause hard
Disk carry fails.Therefore, in order to avoid causing hard disk carry to fail due to this reason, during hard disk carry, work as detection
In the presence of being repeated to UUID, then the corresponding UUID of recording disk, and the carry step that hard disk will be continued to execute.Certainly, in reality
In implementation process, the carry of hard disk can be directly carried out, without detecting whether that there are identical UUID.
Based on above-mentioned any embodiment, it should be noted that it is described by the target hard disk carry to the target directory,
Including：
By preset disk service by the target hard disk carry to temp directory, and obtains the target hard disk and correspond to
OSD ID；
By the target hard disk carry to the target directory, and the target hard disk is unloaded from temp directory pressure
It carries.
Specifically, the detailed process of hard disk carry is：When storage system has detected hard disk grafting, triggering udev rule
Then, and by ceph-disk services hard disk is first mounted to temp directory, after obtaining the information such as the ID of OSD, then is mounted to target
Catalogue, finally from temp directory forced unloading, and then by calling ceph-osd services to start OSD processes.
Based on above-mentioned any embodiment, it should be noted that it is described start the corresponding OSD processes of the target hard disk it
Afterwards, further include：
When terminating the OSD processes using abnormal escape mechanism, and again before carry hard disk, by the OSD processes weight
The number zero setting opened.
If specifically, by the corresponding OSD processes of abnormal escape mechanism target end hard disk, which can be immediately
Reporting fault message is conducive to storage system so that storage system knows specific hard disk, specific running state of a process immediately
Storing system information timely updates.
But after terminating OSD processes by abnormal escape mechanism, exited since storage system is provided with OSD process exceptions
Automatically the protection mechanism restarted, when the number restarted is more than the setting of storage system, just can not restart OSD under the interface into
Journey.Therefore, when passing through the corresponding OSD processes of abnormal escape mechanism target end hard disk, after pulling out target hard disk, the OSD processes
It can attempt to restart, and due to the above-mentioned presence for restarting protection mechanism, it is likely that cause the target hard disk of grafting again or other are hard
Disk cannot achieve carry.
Therefore, after terminating the OSD processes by abnormal escape mechanism, in grafting hard disk again, start hard disk pair
Before the OSD processes answered, the number zero setting for first restarting the OSD processes is restarted to avoid since storage system is preset
Hard disk carry fails caused by protection mechanism.
Based on above-mentioned any embodiment, it should be noted that the process of OSD can also be fallen by the direct core of assert
Mode terminates OSD processes, when using such mode, due to only when other OSD process checks are to the OSD process exceptions,
Reporting fault message so needs certain detection report cycle to make storage system processing slow.And exit machine by abnormal
System terminates OSD processes, understands reporting fault message immediately, is conducive to timely updating for storing system information.
Based on above-mentioned any embodiment, it should be noted that the hard disk hanging method that this specification provides has extensive
Versatility is suitable for any distributed memory system, can significantly improve the efficiency and success rate of hard disk carry, improve storage
