Description

Automatic testing method and device for disk array, electronic equipment and storage medium

Technical Field

The invention relates to the technical field of servers, in particular to an automatic testing method and device of a disk array, electronic equipment and a storage medium.

Background

Since a computer system starts, a hard disk is an indispensable component, no matter an operating system or data storage, the hard disk must be relied on, as a network advances to a cloud computing generation, a lot of electronic service data are transmitted, and the importance of data storage is emphasized, a server needs to face to data access of a large number of network clients, a large number of users provide specific services after being online, and even the server needs to continuously work for 7 × 24 hours, so the importance of keeping the data of the server system stable is needless to say, once the data is damaged and lost, the server system is stopped, and the loss and influence caused by the data are difficult to calculate. Since data storage is so important, IT is an important task for IT personnel to regularly backup data, however, only the backup data is needed, when the hard disk is damaged, the system must be taken off-line to restore the file data, which is not only labor-consuming but also time-consuming, and still cannot satisfy the necessary condition that the server must provide services on-line at any time.

RAID is also known as disk array. Briefly, RAID is a disk with a fault tolerance mechanism. The single hard disk has no fault tolerance mechanism, and any part of the hard disk fails when the fault occurs, however, when the fault occurs, the service which is running on the hard disk is interrupted, and the data disappears. This is very unboosted for the user to use and therefore a RAID mechanism is created. The principle is that an array mode is used as a magnetic disk set, and the data safety is improved by matching with the design of data scattered arrangement. The disk array is a large disk set composed of a plurality of inexpensive, small-capacity, high-stability and slow-speed disks, and the performance of the whole disk system is improved by the additive effect generated by providing data by individual disks. Meanwhile, when data is stored, the data is cut into a plurality of sections by using the technology and the sections are respectively stored on the hard disks. The disk array can also utilize the concept of Parity Check (Parity Check), when any hard disk in the array fails, data can still be read out, and when the data is reconstructed, the data in the failed hard disk is calculated and then is re-placed into a new hard disk.

RAID5 requires at least 3 hard disks, the same-bit data of which is not fixed to the same hard disk, and stores the data and the corresponding parity information in an alternating manner on the respective disks constituting RAID5, and the parity information and the corresponding data are stored on different disks, respectively, where any (N-1) disk stores complete data, that is, there is a space equivalent to a disk capacity for storing parity information. Therefore, when one disk of RAID5 is damaged, the integrity of data is not affected, thereby ensuring the data security. When the damaged disk is replaced, the RAID will also automatically use the remaining parity information to reconstruct the data on that disk to maintain the high reliability of RAID 5.

In order to make the disk array repair itself immediately when the disk array is broken first, Hot Spare (Hot Spare) technology is used, and Hot Spare is used, namely, when a used disk fails, a Spare, powered-up and standby disk replaces the failed disk immediately, and the method is Hot Spare. The hot spare disk does not store any user data thereon. A hot spare disk may be dedicated to a single redundant array or it may be a portion of the entire array hot spare disk pool. While in a particular array there can only be one hot spare disk. When the disk fails, the firmware of the controller can automatically replace the failed disk with the hot spare disk and rebuild the data originally stored on the failed disk to the hot spare disk through an algorithm. Data can only be reconstructed from logical drives with redundancy and the hot spare disk must have sufficient capacity. The system administrator may replace the failed disk and designate the replaced disk as the new hot spare disk.

With the increase of network speed and users, the amount of data stored in servers is increasing, the demand of hard disk capacity is also increasing by multiple times, many server manufacturers have released storage servers, i.e. servers with multiple hard disks as a framework, the number of hard disks is 12 as small as 12, and more hard disks can reach hundreds, manufacturers can continuously perform pressure tests on server storage equipment during research and development manufacturing processes to ensure system stability, or data center IT personnel can perform stability tests on servers before servers are online to avoid machine crash or system halt caused by taking down a large number of files from servers, wherein testing the functionality of disk arrays and hot standby often requires a lot of manpower and material resources, and unnecessary time and manpower waste is caused by errors in manual setting.

No matter the server or the hard disk production manufacturer, in the research and development and manufacturing process, the pressure test can be continuously performed on the storage hardware of the server system to ensure the stability of the system, or the data center IT personnel can perform the stability test on the server before the server is on line to avoid that the server is in a state of crash of a machine or system halt due to the fact that a large number of files are stored, accessed and copied to influence the whole user rights and interests. More particularly, the functionality of the disk array is important to ensure that the hot standby mechanism can be started normally, and the integrity of the file system can be protected in the state that the hard disk is damaged.

FIG. 3 of the present application is a schematic diagram of a conventional manual testing process described in the present patent, which is a testing process using manual techniques, S301 is a preparation of testing environment, S302 is an installation of operating system to U disk, S303 generates a 100GB file in U disk by command, S304 records MD5 check code of 100GB file, S305 creates disk array, S306 sets hot spare hard disk, S307 formats disk array as available file system, S308 copies U disk 100G file to disk array, S309 manually pulls out 1 hard disk of disk array during continuous copying of file, S310 disk array disk will automatically add hot spare hard disk and rebuild, S311 continues copying file, disk array simultaneously rebuilds rebuild, S312 until file copying is completed, disk array rebuild is completed, MD5 check code of file is compared, S313 returns to S305, and creates disk array with a second group, setting another different hard disk as hot spare until all hard disks have been executed with overheat removal and hot spare, S314 indicates that the tester must look at the screen to understand the progress and test result, which is the most traditional manual test method.

Therefore, many automated testing methods have been summarized by the shortcomings of the above techniques:
