Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but 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, fig. 1 is a flowchart of a method for mounting a file system according to an embodiment of the present application.
The specific steps may include:
s101: when a starting-up instruction is received, reading equipment state information from a target file;
the present embodiment may be applied to a server, a computer, and other target devices, and after receiving a power-on instruction, the target device may read device state information from a target file. The device state information is information for describing a state of the target device at the last shutdown (i.e., the latest shutdown). Specifically, the device state information may include shutdown state information and read/write state information. The shutdown state information is information describing a shutdown process of the target device when the target device is last shutdown, and the read-write state information is information describing whether a file system of the target device is executing read-write operation at a certain time. The target file may be a file stored in the target device, and the target file may also be a file stored in another device connected to the target device, and the storage location of the target file is not limited in this embodiment.
S102: judging whether the last shutdown of the target equipment is normal or not according to the shutdown state information;
after the device state information is obtained, the present embodiment may determine the shutdown state information according to the device state information, and further determine whether the last shutdown of the target device is a normal shutdown by analyzing the shutdown state information. Specifically, the shutdown state information records a shutdown process of the target device when the target device is last shutdown, the shutdown process of the target device when the target device is last shutdown can be compared with a standard shutdown process, if the shutdown process of the target device when the target device is last shutdown is the same as the standard shutdown process, the last shutdown can be determined as normal shutdown, and if the shutdown process of the target device when the target device is last shutdown is not the same as the standard shutdown, the last shutdown can be determined as.
S103: judging whether the file system has data read-write operation when the target equipment is powered off last time according to the read-write state information;
after the device state information is obtained, the read-write state information may be determined according to the device state information, and whether a file system has data read-write operation when the target device is powered off last time is determined by analyzing the read-write state information. The read-write state information may record the time of each data read-write operation of the file system, that is, it may be determined that the file system performs the data read-write operation at a certain time according to the read-write state information. Specifically, this embodiment may determine, according to the read-write state information, whether the file system has a data read-write operation when the target device is last powered off, that is, whether the file system is executing the data read-write operation when the target device is last powered off.
S104: if the last shutdown of the target equipment is abnormal shutdown and the file system has data read-write operation during the last shutdown, executing abnormal detection operation on the file system;
if the target device is normally powered off after last power off, the file system is not abnormal no matter whether data read-write operation exists during last power off of the file system; if the file system does not perform the data read-write operation when the target device is last powered off, the file system will not have an exception no matter whether the last power off of the file system is a normal power off. Therefore, in this embodiment, on the basis of detecting the shutdown state in S102 and detecting the read-write state during shutdown in S103, if it is detected that the previous shutdown of the target device is an abnormal shutdown and the data read-write operation exists in the file system during the previous shutdown, it is described that the file system may be abnormal and the abnormality detection operation needs to be performed on the file system. When the file system is performing read-write operations, the target device is abnormally shut down, which may cause data in the file system to be damaged or lost, and at this time, an abnormal detection operation may be performed on the file system.
As a possible implementation manner, if the last shutdown of the target device is a normal shutdown, performing mount operation on the file system; and if the file system does not have data reading and writing operation when the target device is powered off last time, carrying out mounting operation on the file system.
S105: and if the file system is not abnormal, performing mount operation on the file system.
According to the method and the device, when the target device is normally shut down or abnormal power failure occurs but the file system does not have data writing, the file system is not subjected to abnormal detection, and the file system is directly mounted.
In this embodiment, after receiving the boot instruction, the device state information is read from the target file, and the shutdown state and the read-write state of the target device can be determined according to the device state information. Whether the last shutdown of the target equipment is normal can be judged according to the shutdown state information, and whether the file system executes data read-write operation when the target equipment is shutdown last can be judged according to the read-write state information. If the target device is normally shut down, the abnormal detection operation can not be executed on the file system; if the target device does not have data read-write operation during the last shutdown, the abnormal detection operation on the file system is not executed; the last shutdown of the target device is an abnormal shutdown, and when the file system has data read-write operation during the last shutdown, it is described that the file system may have read-write operation abnormality during the last shutdown, an abnormality detection operation needs to be performed on the file system, and a mount operation is performed on the file system after the abnormality of the file system is detected. The file system mounting scheme of the embodiment can reduce the probability of missed detection and invalid detection, and can improve the mounting efficiency of the file system on the premise of ensuring the safety of the file system.
As a further introduction to the corresponding embodiment of fig. 1, the process of constructing the device state information may include: after a shutdown instruction is received, judging whether the shutdown process of the target equipment meets a preset condition or not; if so, judging that the target equipment is normally shut down, and setting the value of a shutdown flag bit in the shutdown state information as a first preset value; if yes, judging that the target equipment is abnormally shut down, and setting the value of a shutdown flag bit in the shutdown state information as a second preset value. According to the method, the shutdown state information comprises the shutdown flag bit, if the shutdown process of the target device meets the preset condition, the value of the shutdown flag bit is set to be a first preset value, and if the shutdown process of the target device does not meet the preset condition, the value of the shutdown flag bit is set to be a second preset value.
Further, the process of determining whether the shutdown process of the target device meets the preset condition may include: judging whether the file system is unloaded or not; judging whether a logical volume manager of the target equipment is closed or not; and if the file system is unloaded and the logical volume manager is closed, judging that the shutdown process of the target equipment meets the preset condition.
Correspondingly, the process of judging whether the last shutdown of the target device is a normal shutdown according to the shutdown state information may be: judging whether the value of a shutdown flag bit in the shutdown state information is the first preset value or not; if yes, judging that the last shutdown of the target equipment is a normal shutdown; if not, judging that the last shutdown of the target equipment is abnormal shutdown. By the mode that whether the target equipment is normally shut down is determined according to the value of the shutdown flag bit, the efficiency of detecting the shutdown state can be improved.
As a further introduction to the corresponding embodiment of fig. 1, the process of constructing the device state information may include: after mounting the file system, detecting whether the file system has data read-write operation according to a preset period; if so, setting the value of the read-write flag bit in the read-write state information to be a third preset value; and if not, setting the value of the read-write zone bit in the read-write state information as a fourth preset value. Correspondingly, the process of determining whether the file system has data read-write operation when the target device is powered off last time according to the read-write state information may include: judging whether the value of the read-write flag bit in the read-write state information is a third preset value or not; if yes, judging that the file system has data read-write operation when the target equipment is shut down last time; if not, judging that the file system does not have data read-write operation when the target equipment is shut down last time. By the method for determining whether the file system has data read-write operation when the target device is powered off last time according to the value of the read-write zone bit, the efficiency of detecting the read-write state can be improved.
In the embodiment, the normal shutdown flag is set during normal shutdown, whether data read-write exists in the file system is detected according to a preset period in a startup state, and the data read-write is marked and recorded in the target file, and when the system is started, the shutdown flag bit and the read-write flag bit are read and the file system detection is judged whether to be carried out through certain logic processing, so that detection is never missed, invalid detection is never carried out, and efficient file system detection is really realized.
The flow described in the above embodiment is explained below by an embodiment in practical use. The embodiment provides a method for detecting an efficient file system, which comprises the following steps:
step 1, compiling a script and adding the script into a timed task of a Linux server, executing the script once every five minutes, detecting whether the existing file system has data reading and writing, and storing a detection result into a file.
And 2, writing a normal shutdown mark into the file after the file system is normally unloaded and the LVM (Logical Volume Manager) is normally closed in the shutdown process.
Step 3, when the storage server is started, adding logic at the mounting logic of the file system, wherein the specific logic is as follows: the storage server has a normal shutdown mark and directly skips file system detection; the storage server does not have a normal shutdown mark, but the file system does not have data reading and writing, and the file system detection is skipped at the moment; and only when the storage server has no normal shutdown mark and the file system has data reading and writing, carrying out file system detection.
According to the embodiment, the normal shutdown mark and the file system read-write mark are added when the storage server is shut down, the marks are read and logically processed when the storage server is started, and the file system is not detected and directly mounted when the server is normally shut down or abnormally powered off but the file system has no data write, so that the file system is prevented from being detected every time the storage server is started, and the situation that the large-capacity file system is not mounted after the storage server is started due to overlong detection time is avoided. By the file system detection mode, the file system detection is not required to be carried out every time the computer is started, and the mounting efficiency of the file system is improved.
