Hello,

Inodes are the data structure of Linux operating system.
Inodes contain vital data about files and folders, such as file ownership, access mode (read, write, execute permissions), and file type.

There are a set number of inodes, which indicates the maximum number of files the system can hold.

You can check inodes from shell by running following command :

Quote:
df -i
Output : (example)
Quote:
[root@Server ~]# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda1 1280000 9156 1270844 1% /
