Abstract

The invention discloses a read-only judgment method of a file system based on analog writing, which comprises the following steps: s1) providing a host IP set to be patrolled; s2) connecting to the host to be inspected through SSH; s3) obtaining a file system list of the host to be inspected; s4) determining whether the file system list of the host to be inspected is read-only by writing the inspection time point in the log file. The file system read-only judgment method based on the analog writing can quickly judge the read-only conditions of all file systems in the target host on the premise of ensuring efficiency and safety, and further can associate distributed storage faults according to the judgment result.

Description

File system read-only judgment method based on analog writing

Technical Field

The invention relates to a method for judging read-only property of a file system, in particular to a method for judging read-only property of a file system based on analog writing.

Background

With the progress of informatization and the high-speed development of services, the application range of distributed storage is continuously expanded, the load-bearing service volume and the importance are gradually improved, and particularly under the condition that the popularization and application range of virtualization and cloud platform application is continuously expanded, the normal operation of all virtual machines on the distributed storage is influenced by the fault of the distributed storage, so that the fault pre-judgment and positioning of the distributed storage are particularly important.

The traditional distributed storage failure judgment mode is as follows: monitoring alarm and on-site inspection; monitoring and alarming, namely directly monitoring the storage operation state in a monitoring mode and sending an alarm when a fault occurs; and (4) field inspection, namely judging whether the storage fails or not by directly checking whether the indicator light of the storage equipment is abnormal or not.

Therefore, the above two methods have the problems of failure prediction failure and insufficient coverage, and a new judgment method is needed.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a file system read-only judgment method based on analog writing, which can quickly judge the read-only conditions of all file systems in an object host on the premise of ensuring efficiency and safety, and further can associate distributed storage faults according to the judgment result.

The technical scheme adopted by the invention for solving the technical problems is to provide a read-only judgment method of a file system based on analog writing, which comprises the following steps: s1) providing a host IP set to be patrolled; s2) connecting to the host to be inspected through SSH; s3) obtaining a file system list of the host to be inspected; s4) determining whether the file system list of the host to be inspected is read-only by writing the inspection time point in the log file.

In the above method for determining read-only of file system based on analog writing, step S2 performs SSH connection verification on the IPs in the aggregate list in parallel, and step S3 lists all file system directories in the host after the verification is passed; the step S4 checks whether a disk _ check.log file exists in the directory, and if so, appends the current patrol date to the file and writes the result of the append operation to the disk _ check.log file under the unified path; and if the log file of disk _ check does not exist in the directory, adding the file and writing the current date, and writing the operation results of adding and adding the date into the log file of disk _ check.

In the above method for determining read-only status of file system based on analog writing, step S3 further includes removing the directories of the optical disc drive and the ISO mirror mount.

The file system read-only judgment method based on the simulated writing further comprises analyzing a routing inspection result in a disk check log file, and outputting an IP which cannot create a disk check log file or has an error written date and a corresponding file system directory list.

Compared with the prior art, the invention has the following beneficial effects: the invention provides a read-only judgment method of a file system based on analog writing.

Detailed Description

The invention is further described below with reference to the figures and examples.

FIG. 1 is a flowchart illustrating the read-only determination of a file system based on an emulated write according to the present invention.

Referring to fig. 1, the method for determining read-only of a file system based on analog writing according to the present invention includes the following steps:

s1) providing a host IP set to be patrolled;

s2) connecting to the host to be inspected through SSH;

s3) obtaining a file system list of the host to be inspected;

s4) determining whether the file system list of the host to be inspected is read-only by writing the inspection time point in the log file.

Referring to fig. 2, the method for determining the read-only status of the file system according to the present invention includes the following steps: entering a host list to be checked, summarizing an IP list, performing SSH connection verification on the IPs in the list in parallel, and listing all file system directories (removing special directories of an optical drive and an ISO mirror image mount) in the host after the verification is passed; checking whether a disk _ check.log file exists in the directory, if so, adding the current patrol date into the file and writing the result of the adding operation into the disk _ check.log file under the unified path; if the directory does not have a disk _ check.log file, newly adding the file and writing the current date, and writing operation results of the newly added and added dates into a disk _ check.log file; after the operations are completed, the inspection result in the disk check log file is analyzed, and the IP and the corresponding file system directory list which cannot create the disk check log file or write the error date are output.

Next, a set of distributed storage A is mounted to the architecture of three application servers to simulate, verify and judge the read-only problem, and the architecture of a sample is shown in FIG. 3; the method comprises the steps that a centralized management server issues verification instructions to hosts to be checked, three hosts to be verified are respectively mounted with distributed storage A, a verification script is issued to the three hosts to be verified through the centralized management server, a read-only file system list is returned, the distributed storage A is associated according to a mounting source of a file system, and whether the distributed storage A has read-only faults or not is finally confirmed.

Although the present invention has been described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
