Detailed Description
In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
As shown in fig. 1, in some embodiments of the present disclosure, a method for locating a fault in a hard disk of a computer is provided, which includes the following steps:
s102, setting soft links, wherein the soft links correspond to the interface positions of the clamping grooves of the hard disk of the computer one by one;
s104, reading all hard disk identification information of all computer hard disks, wherein all hard disk identification information corresponds to all computer hard disks one by one;
s106, reading the information of each drive letter of each computer hard disk;
s108, configuring hard disk positioning information of each computer hard disk, wherein the hard disk positioning information comprises hard disk identification information of the computer hard disk, a soft link corresponding to a clamping slot interface position of the computer hard disk and drive letter information of the computer hard disk;
s110, inquiring hard disk positioning information of the failed hard disk when at least one computer hard disk fails, and uploading soft links in the hard disk positioning information of the failed hard disk.
Specifically, a hot plug script of the computer can be configured, so that when a hard disk is hot plugged on the computer, soft links needed by the user are created according to a predefined rule, the soft links have fixed names and have a one-to-one correspondence with the interface positions of the clamping grooves, and the soft links point to the drive letter information of the hard disk of the computer corresponding to the soft links.
The card slot position of the hard disk can be judged through the soft link. The hard disk identification information includes characters that uniquely identify the hard disk, the characters including SN (Serial Number) codes and/or UUID (Universally Unique Identifier) codes of the hard disk,
the SN acquisition method in the Linux system is exemplified as follows:
smartctl-a[DEV_NAME]，
the method for obtaining UUID in Linux system is exemplified as follows:
ls-la/dev/disk/by-uuid/。
it should be noted that the method for acquiring the SN code and the UUID code of the hard disk is not unique, and may be acquired by other methods, and it is not necessary to use the SN code or the UUID code as a unique identifier of software, and other software information that can uniquely identify a hard disk may also be used.
When a new hard disk is inserted into a clamping groove, the unique software identifier of the hard disk and the disk identifier of the hard disk in mounting are recorded, corresponding soft links are allocated to the hard disk, and the three pieces of information are used as a set of hard disk positioning information configuration to be stored. Thus, the card slot and the unique software identifier are in one-to-one correspondence through a fixed soft link name. When a certain hard disk fails, for example, when a certain hard disk is detected to be unsuccessfully mounted or unloaded, the position of the clamping groove where the hard disk is located can be rapidly positioned by reporting the soft link where the hard disk is located.
In some embodiments of the present disclosure, after the step S108 of configuring the hard disk positioning information of each computer hard disk, the computer hard disk fault positioning method further includes: when a plugging signal of the computer hard disk is detected, an access signal of the computer hard disk is identified, and the read hard disk identification information of the accessed computer hard disk is configured as hard disk positioning information, the drive letter information of the accessed computer hard disk is read again, and the drive letter information of the accessed computer hard disk and a soft link corresponding to the card slot interface position of the accessed computer hard disk are updated to the hard disk positioning information of the accessed computer hard disk; for example, when a hard disk is mounted after the hard disk positioning information has been collected, the mounted hard disk is assigned with the defined soft link and the drive letter information, and the soft link and the drive letter information in the original hard disk positioning information are replaced by the defined soft link and the drive letter information.
In some embodiments of the present disclosure, after the step S108 of configuring the hard disk positioning information of each computer hard disk, the computer hard disk fault positioning method further includes: when a plugging signal of a computer hard disk is detected and an access signal of the computer hard disk is identified, and the read hard disk identification information of the accessed computer hard disk is not configured as hard disk positioning information, reading the disk identifier information of the accessed computer hard disk, and newly adding the hard disk positioning information configured as the accessed computer hard disk, the hard disk identification information of the accessed computer hard disk and a soft link corresponding to the card slot interface position of the accessed computer hard disk; for example, when a new hard disk is inserted into a card slot, the unique software identifier of the hard disk and the disk identifier of the hard disk is recorded, a corresponding soft link is allocated to the hard disk, and the three information are stored as a set of newly added hard disk positioning information configuration.
In some embodiments of the present disclosure, after the step S108 of configuring the hard disk positioning information of each computer hard disk, the computer hard disk fault positioning method further includes: when the plugging signal of the computer hard disk is detected and the access signal of the computer hard disk cannot be identified within a preset time, the hard disk positioning information of the computer hard disk is deleted, for example, when the hard disk is unplugged and is no longer used on the computer or the hard disk needs to be replaced with a clamping groove, the hard disk positioning information stored in the local configuration file and the database of the hard disk is deleted automatically or by manual intervention. If the hard disk is reused, it needs to be used as a new hard disk to re-acquire and configure the hard disk positioning information.
In some embodiments of the present description, the hard disk positioning information is stored in a local configuration file of the computer;
backing up the hard disk positioning information in a database of the computer; when the computer hard disk is mounted, the access priority of the local configuration file is higher than that of the database; for example, when a hard disk is inserted, the local configuration file is preferentially read to complete hard disk mounting, and when the local configuration file is not available, the configuration information stored in the database is read.
In an actual application environment, from the current common storage amount of the hard disk, the storage amount of one hard disk is about T-level, and in order to cope with the storage of massive data, 8-16 hard disks can be generally supported on one computer. If the clamping groove of a certain hard disk is loose or the hard disk is damaged or the hard disk is not mounted successfully or unloaded in the using process, if the fault hard disk is found in a block-by-block hard disk troubleshooting mode, the method is quite large in workload and requires huge time cost, if positioning information of the hard disks can be obtained through some embodiments of the specification, once certain hard disks or the clamping grooves of the hard disks fail, the positioning information of the fault hard disk can be directly reported, and then the fault hard disk is accurately positioned to the clamping groove interface position of the computer hard disk through a soft link in the reported positioning information, so that the working efficiency is greatly improved and the time cost is saved.
