Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The storage device mounting method provided by the application can be applied to the application environment shown in fig. 1. Wherein the storage device 102 can communicate with the server 104 after the mount is successful. When the storage device 102 accesses the server 104, the server 104 needs to mount the accessed storage device 102, the server 104 performs a first repair on the storage device 102 to be mounted, performs a second repair with a larger repair range on the storage device 102 when the first repair result is a repair failure, and mounts the storage device 102 when the second repair result is a repair success. The storage device 102 may be, but is not limited to, various devices for storing information, such as a hard disk, a magnetic tape, a magnetic core memory, a magneto-optical disk, and the like, and the server 104 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a storage device mount method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
Mount, among other things, refers to a process by which a computer operating system makes computer files and directories on a storage device, such as a hard disk or shared resource, available to a user for access through the computer's file system. When the computer is shut down, each mounted storage will undergo an offload to ensure that all queued data is written and to ensure the integrity of the file system structure on the storage device. Specifically, in the Linux operating system, all devices are regarded as files, resources of the entire computer are integrated into a large file directory, and when a file in the storage device needs to be accessed, a partition in which the file is located must be mounted on an existing directory, and then the storage device is accessed by accessing the directory. Therefore, successful mounting of the storage device is a necessary prerequisite for normal access to the storage device. The storage device is a device for storing information, and generally, the information is digitized and then stored in a medium using electricity, magnetism, or optics, such as a hard disk, a magnetic tape, and a magneto-optical disk. When a storage device such as a hard disk has errors and generates a bad track, the corresponding part of the hard disk cannot carry out normal data reading and writing, the bad track of the hard disk is divided into a logic bad track and a physical bad track, the former is a soft bad track which is usually caused by improper software operation or use and can be repaired by software; the latter is a physical bad track, indicating that physical damage is generated on the hard disk track, and can only be solved by changing the use condition of the hard disk partition or sector. The repair is to repair a bad track existing in the storage device, so that the part of the storage device where the error occurs can continue to operate normally. The first repair is a first mode type repair, for example, the repair may be a quick repair, that is, a repair is performed for a critical location in the storage device or a portion where an error easily occurs, and the quick repair is fast and takes little time. The first repair result is a result of the first repair to the storage device, and may include a repair success and a repair failure.
Specifically, when the server detects the storage device to be mounted, for example, when the server enumerates or finds that the storage device of the peripheral device is accessed, the server performs first repair on the storage device, so as to quickly repair a key part of the storage device, and obtain a first repair result.
The second repair is a second mode type repair, for example, a full scan repair may be performed on the storage device, and the full scan repair may traverse all locations of the storage device, so that the storage device may be repaired accurately and fully. The repair range of the second repair is greater than the repair range of the first repair, i.e., the second repair may repair the storage device more accurately and more comprehensively than the first repair.
Specifically, after the server obtains a first repair result after the first repair is performed on the storage device, if the first repair result is a repair failure, that is, it indicates that the problem existing in the storage device cannot be completely solved by the first repair, the server further performs a second repair with a larger repair range on the storage device, so that the gradient repair on the storage device is realized by two repairs with an increased repair range, the comprehensiveness of the repair on the storage device can be improved, and a second repair result is obtained.
And step 206, mounting the storage device when the second repair result is that the repair is successful.
After the second repair result is obtained, if the second repair result is successful, it is indicated that the storage device has been repaired and the corresponding existing problems are solved, normal work can be performed, and the server mounts the storage device, so that normal data read-write operation can be performed through the storage device after the storage device is successfully mounted.
In the storage device mounting method, the detected storage device to be mounted is subjected to first repair, the storage device is subjected to second repair with a larger repair range when the first repair result is that the repair fails, and the storage device is mounted when the second repair result is that the repair succeeds. Before the storage device is mounted, the storage device which fails in the first repair is repaired sequentially through two times of repair, the second repair range is larger than the first repair range, the storage device is mounted after the repair is successful, the storage device can work normally after the mounting of the storage device is successful, the normal storage of data is ensured, and the safety of the data is improved.
In one embodiment, when a storage device to be mounted is detected, performing a first repair on the storage device, and obtaining a first repair result includes: and when detecting that the external storage device is accessed, performing local repair on the storage device until a first repair result comprising a local repair result.
In this embodiment, the first repair is a partial repair, and the first repair result includes a partial repair result. Local repair is a fast mode repair, i.e., repair is performed only on local locations of the storage device, such as locations in the storage device where errors are likely to occur. Specifically, when the server detects that the external storage device is accessed, the server performs local repair on the storage device, so that a local repair result can be quickly obtained.
Further, if the first repair result is successful, that is, it indicates that the storage device has solved the existing errors through the first repair and can normally operate, the server may directly mount the first repaired storage device, and perform data read-write operation through the storage device after the mount is successful.
Further, when the first repair result is a repair failure, performing a second repair on the storage device, and obtaining a second repair result includes: and when the local repair result is a repair failure, performing comprehensive repair on the storage device to obtain a second repair result comprising a comprehensive repair result.
In this embodiment, the second repair is a full repair, and the second repair result includes a full repair result. The comprehensive repair is to comprehensively scan the storage device, traverse all positions of the storage device and repair each position, wherein the repair range of the comprehensive repair is larger than that of the quick repair, and the storage device can be completely and comprehensively repaired. Specifically, when the storage device is locally repaired and the obtained local repair result is a repair failure, the server performs comprehensive repair on the storage device, and traverses all parts of the storage device, for example, traverses all sectors of a hard disk to perform repair, so as to obtain a comprehensive repair result.
In this embodiment, the local repair is performed on the storage device to be mounted first, so that the processing speed of repair can be ensured, and when the local repair is successful, the storage device after the local repair can be directly mounted. When the local repair fails, the storage device is repaired comprehensively to improve the comprehensiveness of the repair. Through two times of gradient repair processing, the processing efficiency of the repair before the mounting of the storage device can be improved on the premise of ensuring the repair effect before the mounting of the storage device.
In one embodiment, after the mounting the storage device, the method further includes: when the storage equipment is mounted successfully and meets preset storage equipment detection conditions, carrying out storage equipment detection on the storage equipment to obtain a storage equipment detection result; and when the detection result of the storage equipment is that the storage equipment is abnormal, sending an abnormal prompt message of the storage equipment.
The storage device detection condition is used for determining that the storage device needs to be triggered to detect, and the storage device detection condition is preset according to actual needs, such as timing detection, instruction trigger detection and the like. The storage device detection is to detect the attribute and function of the storage device to determine whether the storage device can operate normally.
Specifically, after the storage device is mounted, the server obtains a mounting result, if the mounting result indicates that the storage device is successfully mounted, the server monitors whether a preset storage device detection condition is met, if so, the server monitors whether a preset storage device detection period is reached, if so, the server detects the storage device, and if so, the server detects the mounting information and the read-write function of the storage device respectively to obtain a storage device detection result. And if the detection result of the storage equipment is that the storage equipment is abnormal, namely the storage equipment is abnormal and cannot work normally, the server sends a storage equipment abnormity prompting message. In specific application, if the storage device detection result is that the storage device is abnormal, the server can further determine the abnormal type of the storage device, generate a corresponding abnormal prompt message based on the abnormal type of the storage device, and prompt by sending the abnormal prompt message, so as to prompt the abnormal type of the storage device in time. On the other hand, if the detection result of the storage device is that the storage device is normal, which indicates that the storage device can perform normal operation, the server may perform data read-write operation through the storage device, and further, the server may also send a prompt message that the storage device is normal to prompt the state of the storage device.
In this embodiment, when the storage device is successfully mounted and a preset storage device detection condition is met, the server detects the storage device for the storage device, and sends a storage device exception prompt message when the storage device is abnormal and normal operation cannot be performed, so that the state of the storage device can be effectively monitored, and the storage device exception prompt is timely performed to ensure normal operation of the storage device, thereby ensuring data safety.
In an embodiment, as shown in fig. 3, the processing of storage device detection, that is, when the storage device is mounted successfully and a preset storage device detection condition is met, performing storage device detection on the storage device, and obtaining a storage device detection result includes:
In this embodiment, the storage device detection condition includes a storage device detection period. The storage device detection period is a period for detecting the storage device at regular time, and can be flexibly set according to actual needs, for example, the period can be set to 12 hours, that is, the storage device is detected every 12 hours. The detection period of the storage device can be specifically set according to the application environment of the storage device, and if the data of the storage device is frequently read and written, the value of the detection period of the storage device can be set to be smaller; and when the data read-write interval time of the storage device is longer, the value of the detection period of the storage device can be set longer, so that the detection resources are more effectively utilized on the premise of ensuring the detection effect of the storage device. The mount information is attribute information of the storage device, and may specifically include file system information of the storage device, such as whether the storage device is readable and writable, whether there is a recording error, whether there is a "specific character string" in the initial plurality of sectors, and the like.
Specifically, when it is determined that the mount result of the storage device represents that the mount is successful and the storage device detection period is reached, the storage device is triggered to be detected, the server detects mount information of the storage device, and if the server can acquire file system information of the storage device to perform anomaly detection, the mount information detection result is obtained.
And step 304, performing read-write detection on the storage device to obtain a read-write detection result.
The read-write detection is to detect whether the storage device can perform normal read-write, and if the storage device can perform normal read-write, that is, the read data corresponds to the actually written data, the storage device is reliable, and data read-write operation can be performed based on the storage device. On the contrary, if the reading and writing of the storage device are abnormal, that is, the read data does not correspond to the actually written data, the storage device is unreliable, and if the data reading and writing operation is performed through the storage device, data loss or errors can be caused, and data safety is affected.
Specifically, the server performs read-write detection on the storage device, and specifically, may write specific test data into the storage device, re-read the data from the storage device, and compare the re-read data with the written data to obtain a read-write detection result.
And step 306, obtaining a storage device detection result according to the mounting information detection result and the read-write detection result.
And after the mounting information detection result and the read-write detection result are obtained, the server combines the mounting information detection result and the read-write detection result to obtain a storage device detection result. Specifically, if any one of the mount information detection result and the read-write detection result is abnormal, the storage device detection result is detected to be abnormal; and when the mounting information detection result and the read-write detection result are both detected normally, the storage device detection result is detected normally. During specific implementation, if the detection result of the storage device is abnormal, the storage device is indicated to be abnormal, and normal operation cannot be performed, the server can send a prompt message to prompt the storage device to perform abnormal processing; if the storage device detection result is that the detection is normal, the device read-write operation can be performed based on the storage device, and the storage device is repeatedly detected after waiting for the next storage device detection period.
In the embodiment, the mounting information and the read-write function of the storage device are detected regularly, so that the abnormality of the storage device can be found in time, and the influence on the data security when the data is read and written through the abnormal storage device is avoided.
In one embodiment, detecting mounting information of a storage device, and obtaining a mounting information detection result includes: acquiring file system information of a storage device; respectively carrying out anomaly detection on various types of system information in the file system information to obtain a file system information detection result; and obtaining a mounting information detection result based on the file system information detection result.
In this embodiment, the mount information of the storage device includes file system information, which may specifically include, but is not limited to, various types of system information including whether to be readable and writable, whether to have a recording error, whether to have a "specific character string" in the initial sectors, and the like. Whether the storage equipment supports read-write operation or not is determined, and whether the storage equipment is changed into read-only attribute or not is determined; whether a recording error exists is used for determining whether an error exception exists in the storage device; whether the initial sectors have "special strings" is used to determine whether certain erroneous strings exist in the first few sectors of the storage device. Generally, if there is a specific character string in the first few sectors of the storage device, errors may have occurred in other parts of the storage device, so that it can be determined whether the storage device is abnormal.
Specifically, when detecting mount information of the storage device, the server obtains file system information of the storage device, and may specifically detect attribute information of the storage device to obtain the file system information of the storage device. And after the file system information of the storage device is obtained, the server respectively performs exception detection on various types of system information in the file system information to obtain a file system information detection result. For example, the file system information may include various types of system information such as whether the file system information is readable and writable, whether a recording error exists, whether specific character strings exist in initial sectors, and the like, and the server may perform anomaly detection on the various types of system information, such as whether the storage device supports reading and writing according to identification information that is readable and writable in the file system information, whether an error exists in the storage device according to identification information that is whether a recording error exists in the file system information, and may also perform character string matching on character string information of the initial sectors of the storage device, to determine whether specific character strings exist in the initial sectors, thereby determining whether the storage device is anomalous. The file system information detection result comprises an abnormal detection result corresponding to each type of system information.
After obtaining the file system information detection result, the server obtains a mount information detection result based on the file system information detection, for example, the file system information detection result may be directly used as the mount information detection result; or analyzing the abnormal detection results respectively corresponding to various types of system information in the file system information detection results, and sequencing according to the abnormal severity to obtain the mounting information detection results.
In this embodiment, each type of system information in the file system information of the storage device is respectively subjected to anomaly detection, a mount information detection result is obtained based on the obtained file system information detection result, the storage device can be subjected to anomaly analysis based on the file system information of the storage device, and it can be determined that the normal or abnormal state of the storage device is monitored, so that the normal operation of the storage device is ensured.
In one embodiment, performing read-write detection on the storage device, and obtaining a read-write detection result includes: acquiring read-write test data respectively corresponding to each sector in the storage device; writing the read-write test data into the sectors corresponding to the storage equipment, and respectively reading the read-write test data from the sectors corresponding to the storage equipment to obtain sector test data; and obtaining a read-write detection result based on a comparison result between the sector test data and the read-write test data.
The sector refers to a divided area on a storage device such as a magnetic disk, each magnetic track on the magnetic disk is equally divided into a plurality of arc segments, the arc segments are sectors of the magnetic disk, and the reading and writing of the hard disk take the sectors as basic units. The read-write detection of the storage device needs to be performed by re-reading after specific data is written in each sector of the storage device, so that the read-write detection of each area of the storage device is realized.
Specifically, when performing read-write detection on the storage device, the server acquires read-write test data corresponding to each sector in the storage device, and the read-write test data is generated in advance according to actual requirements, and random number data can be generated through a specific data generation algorithm, for example, through a random number generation algorithm. In order to distinguish read and write of each area in the storage device, the read and write test data may correspond to each area of the storage device, that is, different areas may correspond to different read and write test data, thereby ensuring the accuracy of read and write detection. After the read-write test data are obtained, the server writes the read-write test data into the corresponding sectors of the storage device, and different sectors can write corresponding different read-write test data. And the server respectively reads sector test data from the sectors corresponding to the storage equipment, wherein the sector test data refers to data obtained by re-reading the read-write test data after the read-write test data is written into the storage equipment. And the server compares the sector test data with the read-write test data, and obtains a read-write detection result according to a comparison result. Specifically, the sector test data and the read-write test data corresponding to each sector in the storage device can be compared one by one, if the comparison is consistent, it is indicated that the sector test data read from the sector is consistent with the read-write test data written into the sector, i.e. the read-write is consistent, the read-write function of the sector is normal, and the data security can be ensured; if the comparison is inconsistent, it indicates that the reading and writing of the sector are inconsistent, and the reading and writing function of the sector is abnormal, so that the data security cannot be ensured. The read-write detection result reflects the read-write function state of the storage device, and in specific implementation, the read-write detection result can include the sector read-write detection result corresponding to each sector in the storage device, so that the read-write of each sector of the storage device is visually fed back. In addition, the read-write detection result may also include a determination of the whole read-write function of the storage device, for example, when the number of sectors with abnormal read-write in the storage device exceeds a preset abnormal number threshold, the number of sectors with abnormal read-write in the storage device is considered to be too large, and the storage device is not trusted, so the read-write detection result may be abnormal read-write.
In the embodiment, the read-write test data is directly and respectively written into each sector of the storage device to read the data, and the read-write detection result of the storage device is obtained according to the comparison result between the re-read sector test data and the read-write test data, so that the read-write function of each sector in the storage device is detected in a direct read-write mode, the read-write function state of the storage device can be accurately determined, and the normal work of the storage device is ensured.
