How to check inode usage in Linux

Question

How to check inode usage in Linux?

I'm managing a Linux server and need to monitor inode usage to prevent issues with file limits. Can someone explain how to check inode usage on my system? Are there specific commands I should use, and what should I look for in the output to understand inode consumption? Any advice on interpreting the results would be great!

You can use the df command with the -i option as it displays inode usage for all mounted filesystem.

Check Inode Usage with df -i:

Run the following command in the terminal:

df -i

This will display the inode usage statistics for all mounted filesystems, showing the following columns:

Filesystem: The name of the filesystem.

Inodes: Total number of inodes.

IUsed: Number of inodes currently in use.

IFree: Number of free inodes.

IUse%: Percentage of inodes in use.

Mounted on: The directory where the filesystem is mounted.
