inode

the file system uses inode numbers to uniquely identify each file and directory.

administrators can check inode usage to prevent running out of file system resources.

the inode table contains metadata for all files stored on the partition.

each inode stores information such as file size, permissions, and timestamps.

when the inode limit is reached, the system cannot create new files.

the inode cache improves performance by reducing disk access for file metadata.

file system tools can display detailed inode information for troubleshooting.

the inode structure includes pointers to the actual data blocks on disk.

running out of inodes is different from running out of disk space.

the inode bitmap tracks which inodes are free and which are allocated.

every directory entry contains a mapping between a filename and its corresponding inode number.

some file systems allow administrators to tune inode size for better performance.

inode flags control special behaviors like immutability or append-only access.
