Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a flowchart of an implementation of a RAID executable file updating method provided in an embodiment of the present application may include the following steps:
s110: when updating the kernel disk array RAID executable file of the system, copying an upgrade compression package and a check file to be used to a set directory of a set partition of a system disk in advance.
The partition is set to be not the first partition.
In practical applications, during the use of the storage device, a user may have new requirements for existing services, which may require updating the kernel RAID executable file of the system. As described in the background art, simply performing replacement of a RAID executable file may cause that a file replaced before starting cannot be valid because a system re-decompresses a compressed packet such as a start file and a dependent file to a first partition of a system disk when starting, so that the RAID executable file is not successfully replaced.
Based on the problem, when the kernel RAID executable file of the system is to be updated, the update compression package and the check file to be used are copied to the set directory of the set partition of the system disk in advance. The set partition is not the first partition. Therefore, when the system is started and the compression packages such as the starting files, the dependent files and the like are decompressed again to the first partition of the system disk, the upgrading compression packages cannot be replaced by the decompressed starting files, the dependent files and the like.
Specifically, the upgrade compressed package and the check file may be copied to a system directory/mnt/log, where the/mnt/log directory is in the sixth partition of the system disk.
In the embodiment of the application, the upgrade compression package is generated by performing package compression on a directory in the system based on an original file corresponding to the RAID executable file to be used. The directory of the RAID executable file to be updated in the system may be obtained first, based on the directory format, a corresponding directory is established on the control device, the RAID executable file to be used is placed in the directory, and the package compression is performed to generate the upgrade compression package.
A RAID executable to be used refers to a file that is to replace a corresponding original file in the system. The RAID executables to be used may include bmbo.ko, md-mod.ko, RAID0.ko, RAID10.ko, RAID456.ko, rdbk.ko, etc. The format of the generated upgrade compression package is as follows: dcs 02-version number, update.
After the upgrade compression package is generated, a check value of the upgrade compression package, such as MD5 code, may be generated and recorded in the check file. The check file may be a chksum.
S120: and restarting the system, and determining whether the upgrading compression package is complete or not based on the check file in the starting process of the system.
The operation of step S110 may be regarded as a preparation work that needs to be performed when the kernel disk array RAID executable file of the system is to be updated. After the upgrade compression package and the check file to be used are copied to the set directory of the set partition of the system disk, the system can be restarted.
In the system starting process, whether the upgrading compression package is complete or not can be determined based on the check file. That is, whether the upgrade compression package in the set directory is complete is determined by checking the check value recorded in the file. So as to timely find the condition that the upgrade compression package is damaged or incomplete due to incomplete copying in the copying process. And the check value of the upgrading compression packet recorded in the check file is the original check value of the upgrading compression packet.
In one embodiment of the present application, whether the upgrade compression package is complete may be determined by:
the method comprises the following steps: calculating a first check value of the upgrading compression packet;
step two: and if the first check value is the same as the original check value recorded in the check file, determining that the upgrade compression package is complete.
That is, the first check value of the upgraded compressed packet in the set directory may be calculated first, the first check value is compared with the original check value recorded in the check file, and if the first check value is the same as the original check value recorded in the check file, it may be determined that the upgraded compressed packet is complete. If the update information is not the same as the update information, the update information can be output to prompt a technician to perform problem troubleshooting in time.
And the integrity of the upgrade compression package is verified, so that the condition that the storage equipment cannot be normally used after the damaged RAID executable file replaces the corresponding original file can be avoided.
S130: and if the upgrading compression package is determined to be complete, decompressing the upgrading compression package to obtain the RAID executable file to be used.
After the upgrading compression package is determined to be complete, the upgrading compression package can be decompressed, and a RAID executable file to be used is obtained.
S140: and respectively replacing the corresponding original files in the system with the obtained RAID executable files.
In the embodiment of the application, after the RAID executable files to be used are obtained, the obtained RAID executable files may respectively replace corresponding original files in the system. The upgrading compression packet is generated by packaging and compressing the directories in the system based on the original files corresponding to the RAID executable files to be used, the upgrading compression packet is decompressed, the directories in the system of the original files corresponding to the obtained RAID executable files can be obtained, accordingly, the RAID executable files can be respectively replaced by the corresponding original files, the files can be updated, and the system upgrading is completed.
By applying the method provided by the embodiment of the application, when the kernel RAID executable file of the system is to be updated, the upgrading compression packet and the check file to be used are copied to the set directory of the set partition of the system disk in advance, the system is restarted, in the starting process of the system, when the upgrading compression packet is determined to be complete based on the check file, the upgrading compression packet can be decompressed to obtain the RAID executable file to be used, and each RAID executable file is respectively replaced by the corresponding original file in the system to update the file, so that the system is updated. The upgrading compression package to be used is copied to the set directory of the set partition which is not the first partition, so that when the system is started up and the compression packages such as the starting file and the dependent file are re-decompressed to the first partition of the system disk, the upgrading compression package cannot be replaced by the decompressed starting file and the decompressed dependent file, and the effective updating of the RAID executable file can be realized.
In an embodiment of the present application, after replacing the corresponding original file in the system with each obtained RAID executable file in step S140, the method may further include the following steps:
the first step is as follows: calculating a second check value of a compressed package composed of the updated RAID executable files in the system;
the second step is that: and if the second check value is the same as the original check value recorded in the check file, determining that the kernel RAID executable file of the system is successfully updated.
For convenience of description, the above two steps are combined for illustration.
After the obtained RAID executable files are respectively replaced with the corresponding original files in the system, a second check value of a compressed packet formed by the updated RAID executable files in the system may be calculated, the second check value is compared with the original check value recorded in the check file, and if the second check value is the same as the original check value, it may be determined that the kernel RAID executable files of the system are successfully updated, and prompt information of the success of the update may be output.
If the second check value is different from the original check value recorded in the check file, the kernel RAID executable file of the system is not updated successfully, and prompt information aiming at the failure of updating the kernel RAID executable file of the system can be output, so that technicians can perform corresponding problem troubleshooting.
In one embodiment of the present application, step S120 may include the steps of:
in the starting process of the system, the initialized system file is called, and the updating script of the loading module function initial position of the initialized system file is executed, so that whether the upgrading compression package is complete or not is determined based on the check file.
In the embodiment of the application, the update script update.sh can be written in advance, and the update script can determine whether the upgrade compression package is complete or not based on the check file. Furthermore, when the upgrading compression package is determined to be complete, the upgrading compression package is decompressed, and the obtained RAID executable files are respectively replaced by corresponding original files in the system.

Sysinit is a script called when starting up every time, and a RAID executable file to be used is replaced into a system when starting up every time, so that update of the file is achieved.
The initialization system file is in a second partition mount directory of the system disk, and specifically, the modified initialization system file rc.sysini can be copied into the system directory/etc/rc.d, so that the rc.sysnine is replaced. The/etc directory is a second partition mounting directory of the system disk, and ensures that when the system is started and the compression packages such as the starting files, the dependent files and the like are re-decompressed to the first partition of the system disk, the initialization system files cannot be replaced by the decompressed starting files, the dependent files and the like.
In the starting process of the system, the initialized system file is called, and because the starting position of the loading module function of the initialized system file is added with a command for executing the updating script, the updating script can be executed in the process of calling the initialized system file, so as to determine whether the upgrading compression package is complete based on the check file, further, when the upgrading compression package is determined to be complete, the upgrading compression package is decompressed, and the obtained RAID executable files are respectively replaced with corresponding original files in the system.
