Because the number of files (corresponding to the number of file index nodes) that can be used in the file system is limited, when the storage device is formatted, the operating system separately allocates an Inode area for storing information contained in the file index nodes, and in the operating system of Linux, one file or folder is an Inode. The file index node mainly stores metadata such as creator, date and size of a file, one index node is occupied when a file is created, and when a large number of files are created, the total number of the file index nodes is used up, so that a large amount of residual disk space exists in the partition, but a new file cannot be created due to the fact that the index nodes are used up.

All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Furthermore, as used in the examples 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 can be included in at least one embodiment of the invention. The appearances of the phrase 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. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments 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 the mount point of the file or the data is in a monitoring partition, monitoring the change percentage of the available index nodes of the partition and the change percentage of the residual space.
In this step, the Linux VFS (virtual machine file system) is an abstraction layer that provides a uniform file access interface upwards, and is compatible with a variety of different file systems downwards. In 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 a partition to be monitored:
if the mount point of the file or the data is not in the monitoring partition, no processing is needed;
and if the mount point of the file or the data is in a monitoring partition, monitoring the change percentage of the available index nodes of the partition and the change percentage of the residual space.
In a specific embodiment, the total number of index nodes and the total size of space of the listening partition may be obtained through an API (Application Programming Interface), the number of remaining index nodes and the size of remaining space may be obtained in real time, and the change percentage of the available index nodes and the change percentage of the remaining space may be calculated according to the number of remaining index nodes and the size of remaining space of the listening 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 partitions can be more effectively prevented from being used up and the space in the partitions can be more effectively prevented from being used up.
Step S102, if the change percentage of the available index nodes of the listening partition and the change percentage of the remaining space exceed the change threshold, file creation or data writing is limited.
In this step, a change threshold of the change percentage of the available inode 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 remaining space of the partition does not exceed the change threshold, updating the record value; if the change percentage of the available index nodes or the remaining space of the partition exceeds the change threshold, reporting is performed, for example, a message is sent to a listening service through a Netlink.
In order to prevent the inode or the residual space from being used up, which results in abnormal termination of the listening service and cannot be used, file creation or data writing needs to be limited.
Specifically, if the change percentage of the available index nodes or the remaining space is greater than or equal to the first change threshold, no processing is required;
if the change percentage of the remaining available index nodes or the change percentage of the remaining space is smaller than a first change threshold and is larger than or equal to a second change threshold, limiting the common application to create the file or write the data, but not limiting the system application to create the file or write the 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.
Wherein the general application and the system application can be distinguished according to the EUID (valid user ID).
The first variation threshold is smaller than the second variation threshold, for example, the first variation threshold is 2%, the second variation threshold is 1%, and other values are also possible, which is not limited in the present invention.
And step S103, monitoring the number of index nodes in the partition.
In this step, the number of index nodes of each application in the snoop partition can be obtained by scanning. Every time a file is created, the number of index nodes is increased by one, so that the number of files and the number of index nodes can be in a one-to-one correspondence relationship. For example, the scanning of the number of files under the data/data/directory is executed, and because all folders under the directory are named by the name of the system apk packet, 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 also 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 sorted according to the occupation ratio.
Step S104, if the index node occupation ratio of the monitoring partition exceeds the early warning threshold, repairing the applications of which the index node occupation ratio sequence exceeds the sequencing 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 a partition may include three states: safety state, pre-warning state and danger state, as shown in fig. 2.
Correspondingly, a safety threshold and an early warning threshold of the index node occupation ratio are preset.
If the index node occupancy ratio in the monitoring partition does not exceed the safety state threshold value, for example, the index node occupancy ratio does not exceed 85%, the monitoring partition is in a safety state, and processing is not needed at the moment;
the early warning state is established if the inode occupancy ratio within the listening partition exceeds the security state and does not exceed the early warning threshold, e.g., the inode occupancy ratio exceeds 85% and does not exceed 95%. And sending a reminding message to the user, for example, popping up a dialog box to remind the user, recommending that the index node occupies more applications, so that the user can repair the applications according to the problems in the dialog box, for example, selecting manual clearing, and certainly, the user can also select to ignore the problems in the dialog box without processing.
And if the index node occupancy rate in the listening partition exceeds an early warning threshold, for example, the index node occupancy rate exceeds 95%, the listening partition is in a dangerous state. And repairing the applications with the index node occupation ratios exceeding the sorting threshold, for example, repairing the applications with the index node occupation ratios more than the top ten times of the sorting in the listening partition, so that the index node occupation ratios in the listening partition are smaller than the safety threshold.
The method for monitoring, early warning and repairing the file index nodes in the embodiment of the invention monitors the index nodes in the partitions actively. And when the system creates or deletes the file, acquiring the number state of the index nodes in real time. And scanning all the application data, sequencing the applications in the scanning result according to the occupation ratio of the index nodes, and intelligently recommending the applications needing processing to a user so that the occupation ratio of the index nodes in the monitoring partition is smaller than a safety threshold value. The application layer may also be automatically repaired if the user is not processing. Therefore, the problem that the power cannot be started due to exhaustion of the index nodes can be effectively prevented. For terminals with frequent user interaction, such as mobile phones, the user can find problems as soon as possible and make a judgment according to intelligent recommendation, and for unattended commercial terminal equipment, automatic repair can be performed under the condition that the limit is reached. 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 effectively prevented.
