How do I check my inode usage?

How do I check my inode usage? You can easily check inode usage using df -i command, as shown below. It will list inode usage of all disk partitions on your Linux system. In the above output, the column IUse% indicates the inode usage in Linux. If you use Ext2/Ext3/Ext4 filesystem, you can also use tune2fs utility tool.

What is inode utilization in Linux? Inode is a Linux (and other Unix-like) data structure used to keep information about the files, folders, emails, code, and everything else on your server. The number of inodes corresponds the number of files and folders you have.

How do I count inodes in Linux? 

To get the inode usage for the root partition using df , use the following syntax.
  1. $ df -i / Filesystem Inodes IUsed IFree IUse% Mounted on /dev/nvme0n1p5 7692288 652294 7039994 9% /
  2. $ sudo tune2fs -l /dev/nvme0n1p5 | grep -Ei ‘inode count|free inode’ Inode count: 7692288 Free inodes: 7040110.

What does high inode usage mean? high inode usage typically indicates lots of small files (or perhaps filesystem corruption). if you run out of inodes, you will not be able to create additional files and so the disk will be ‘full’ regardless of its actual available capacity in MB/GB/TB.

Can two files have same inode number?

Each file in a filesystem has a unique inode number. Inode numbers are guaranteed to be unique only within a filesystem (i.e., the same inode numbers may be used by different filesystems, which is the reason that hard links may not cross filesystem boundaries).

How do I count inodes in a directory?

To get the number of inodes of files in a directory, for example, the root directory, open a terminal window and run the following ls command, where the -l option means long listing format, -a means all files and -i mean to print the index number of each file.
