- Log in to your account using SSH.
- To make sure you are in your home directory, type the following command: cd ~
- To determine the total inode count for your account, type the following command:
What is inode utilization in Linux?
The inode stands for index node or index number is a data structure in a Linux file system that stores information about a file and directory. No space left on device or running out of Inodes. Inode stores the following information about a file.
How do you reduce inode usage?
Here are some steps to reduce the inode number limit.
- 1) Delete unnecessary files and folders. Examine the files and folders manually and decide on if the file is necessary or not.
- 2) Clear old and Spam Emails. Deleting the old emails helps a lot in decreasing the inode usage.
- 3) Clear the cache files.
What is the inode number in Linux?
What is inode number in Linux ? An inode is an entry in inode table, containing information ( the metadata ) about a regular file and directory. An inode is a data structure on a traditional Unix-style file system such as ext3 or ext4.
What is zombie process in Linux?
A zombie process is a process whose execution is completed but it still has an entry in the process table. Zombie processes usually occur for child processes, as the parent process still needs to read its child’s exit status. This is known as reaping the zombie process.
What happens to inode when file is deleted?
Lets see what happens to the structure of the inode if the file music.mp3 is deleted. But the inode and the blocks where the data is stored are just marked as unused so that this inode number and data blocks can be reused. So you can easily recover the data, with just the information contained in the inode structure.
What information is stored in inode?
The inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block location(s) of the object’s data.

How do I check my inodes in cPanel?
To see the general File Usage, move to Stats section on your left: If you wish to see detailed statistics, navigate to the Inodes Usage menu: Then expand the list of folders and inodes. The latter indicates the whole number of files, folders, emails and anything else stored in the whole cPanel account.
How big is an inode?
Specify the size of each inode in bytes. mke2fs creates 256-byte inodes by default. In kernels after 2.6.10 and some earlier vendor kernels it is possible to utilize inodes larger than 128 bytes to store extended attributes for improved performance. The inode-size value must be a power of 2 larger or equal to 128.
How does inode work Linux?
I must say that its a data structure that keeps track of all the information about a file. You store your information in a file, and the operating system stores the information about a file in an inode(sometimes called as an inode number). Information about files(data) are sometimes called metadata.
What is meant by inode in Linux?

What is defunct process Linux?
On Unix and Unix-like computer operating systems, a zombie process or defunct process is a process that has completed execution but still has an entry in the process table. If original parent hasn’t reaped it before its own exit then init process ( pid == 1 ) does it at some later time.
Why zombie process is created in Linux?
Zombie Processes and their Prevention. Zombie state : When a process is created in UNIX using fork() system call, the address space of the Parent process is replicated. If the parent process calls wait() system call, then the execution of parent is suspended until the child is terminated.
What is Process explain?
In computing, a process is the instance of a computer program that is being executed by one or many threads. It contains the program code and its activity. Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently.
How do you reap a child process?
- fork()spawns new process group.
- exit()terminates own process.
- wait()and waitpid() wait for and reap terminated children.
- execl()and execve() run a new program in an existing process.
- kill()send arbitrary signal to process or process group.
What is file descriptor in Linux?
In Unix and related computer operating systems, a file descriptor (FD, less frequently fildes) is an abstract indicator (handle) used to access a file or other input/output resource, such as a pipe or network socket. File descriptors form part of the POSIX application programming interface.
What is journaling in Linux?
A journaling file system is a file system that keeps track of changes not yet committed to the file system’s main part by recording the intentions of such changes in a data structure known as a “journal”, which is usually a circular log.
