The file index node mainly stores metadata such as creator, date, size and the like of the file, each file is created to occupy one index node, when a large number of files are created, the total number of the file index nodes is exhausted, and therefore a large amount of residual disk space exists in the partition, but new files cannot be built because the index nodes are exhausted.

All other embodiments, based on the embodiments of the invention, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the invention. Furthermore, as used in the embodiments of the invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
In order to make the person skilled in the art better understand the solution of the present invention, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.
The embodiment of the invention provides a method for monitoring, early warning and repairing a file index node. As shown in fig. 1, the method comprises the steps of:
step S101, when creating a file or writing data, if a mounting point of the file or the data monitors a partition, monitoring the change percentage of the available index nodes and the change percentage of the residual space of the partition.
In this step, linux VFS (virtual machine file system) is an abstraction layer that provides a unified file access interface upwards, while downwards is compatible with various different file systems. At the Linux VFS layer, when a user creates a file and writes data, it is checked whether the mount point of the file or data is in the partition to be monitored:
if the mounting point of the file or the data is not in the monitoring partition, no processing is needed;
if the mounting point of the file or the data monitors the partition, monitoring the change percentage of the available index nodes and the change percentage of the residual space of the partition.
In a specific embodiment, the total number of index nodes and the total size of space of the monitoring partition can be obtained through an API (Application Programming Interface ), the number of remaining index nodes and the size of remaining space are obtained in real time, and the change percentage of the available index nodes and the change percentage of the remaining space are calculated according to the number of remaining index nodes and the size of remaining space of the monitoring partition and the total number of index nodes and the total size of space.
In the embodiment of the invention, the change percentage of the available index nodes and the change percentage of the residual space are used as judgment bases, so that the index nodes in the partition can be more effectively prevented from being used up and the space can be more effectively prevented from being used up.
Step S102, if the change percentage of the available index nodes and the change percentage of the residual space of the monitoring partition exceed the change threshold, the creation of files or the writing of data is limited.
In this step, a change threshold of the change percentage of the available index node or the remaining space is set in advance, for example, the change threshold is set to 1%. If the change percentage of the available index nodes or the residual space of the partition does not exceed the change threshold value, updating the record value; if the change percentage of the available index nodes or the residual space of the partition exceeds the change threshold value, reporting is performed, for example, a message is sent to a monitoring service through a Netlink.
To prevent inodes or remaining space from running out, resulting in the listening service being abnormally terminated from being unusable, it is necessary to limit creation of files or writing of data.
Specifically, if the change percentage of the available index node or the residual space is greater than or equal to a first change threshold value, no processing is needed;
if the change percentage of the remaining available index nodes or the change percentage of the remaining space is smaller than the first change threshold value and larger than or equal to the second change threshold value, limiting the common application to create files or write data, but not limiting the system application to create files or write data;
if the percentage of change of the available inodes or the percentage of change of the remaining space is less than a second change threshold, all applications are restricted from creating files or writing data.
Among them, the general application and the system application can be distinguished according to EUID (effective user ID).
The first change threshold is smaller than the second change threshold, for example, the first change threshold is 2%, and the second change threshold is 1%, but may be other values, which is not limited in the present invention.
Step S103, monitoring the number of index nodes in the partition.
In this step, the number of index nodes of each application in the listening partition may be obtained by scanning. The number of index nodes is increased by one every time a file is created, so that the number of files and the number of index nodes can be in one-to-one correspondence. For example, the number of files under the directory is scanned, and the folders under the directory are named by the system apk package name, so that the total number of files created by each application can be known according to the scanning result, and the number of index nodes occupied by each application is obtained.
Further, the index node occupation ratio of each application is calculated according to the obtained index node number of each application, and the applications are ordered according to the occupation ratio.
And step S104, if the index node occupation ratio of the monitoring partition exceeds the early warning threshold, repairing the application of which the index node occupation ratio is ordered to exceed the ordering threshold so that the index node occupation ratio in the monitoring partition is smaller than the safety threshold.
In this step, the number of index nodes in the partition may include three states: safety, early warning and dangerous conditions, as shown in fig. 2.
Correspondingly, a safety threshold and an early warning threshold of the index node occupation ratio are preset.
If the occupation ratio of the index nodes in the monitoring partition does not exceed the safety state threshold, for example, the occupation ratio of the index nodes does not exceed 85%, the monitoring partition is in a safety state, and no processing is needed at the moment;
if the index node occupation ratio in the monitoring partition exceeds the safety state and does not exceed the early warning threshold, for example, the index node occupation ratio exceeds 85% and does not exceed 95%, the monitoring partition is in the early warning state. And sending a reminding message, such as a pop-up dialog box, to the user to remind the user, wherein the recommended index node occupies more applications, so that the user can repair the applications according to the problems in the dialog box, such as selecting manual cleaning, and the user can choose to ignore the problems in the dialog box and not process the problems.
If the index node occupation ratio in the monitoring partition exceeds the early warning threshold, for example, the index node occupation ratio exceeds 95%, the monitoring partition is in a dangerous state. And repairing the application of which the index node occupation ratio is greater than the ordering threshold, for example repairing the application of which the index node occupation ratio in the monitoring partition is greater than the first ten in order, so that the index node occupation ratio in the monitoring partition is smaller than the safety threshold.
According to the method for monitoring, early warning and repairing the file index nodes, the index nodes in the partition are actively monitored. When the system creates or deletes the file, the number state of the index nodes is obtained in real time. And scanning all application data, sequencing the applications in the scanning result according to the index node occupation ratio, and intelligently recommending the applications to be processed to the user, so that the index node occupation ratio in the monitoring partition is smaller than a safety threshold. The application layer may also automatically repair if the user is not processing. Therefore, the problem that the power-on cannot be performed due to the fact that the index node is used up can be effectively prevented. For terminals with frequent user interaction like mobile phones, users can find problems early and judge according to intelligent recommendation, and for unattended commercial terminal equipment, the terminal can be repaired automatically under the condition of reaching the limit. Although the negative result of deleting the user data by mistake can be brought, the serious result brought by the fact that the equipment cannot be started can be prevented very effectively.

The steps are not strictly limited in order and may be performed in other orders, unless explicitly stated herein.
