In the Linux system, mounting a hard disk is a very common operation, because it has many benefits. By mounting a hard disk, it can not only expand storage space, separate data, but also improve security and reliability. Next, through this article, I will give you a detailed introduction to "the reason why the Linux system mounts the hard disk".
In Linux, mounting a hard disk is the process of connecting the file system of the hard disk to a directory in the file system hierarchy. The purpose of mounting a hard disk is to enable the data in the hard disk to be accessed and operated in a specified directory.
The following are the specific reasons for mounting the hard disk:
1. Expand storage space: By mounting a hard disk, you can add additional hard disk capacity to the system to expand the storage space. This is useful for storing large amounts of data or running applications that require large amounts of disk space.
2. Data analysis: Sometimes, you may want to store different types of data on different hard drives. By mounting hard drives, you can divide and organize data between different file systems, improving the flexibility and efficiency of data management.
3. System security and reliability: Mounting a specific hard disk to a key directory can help separate system files and user data, reducing accidental operations on system files. In addition, mounting a hard disk can also provide backup and redundancy functions, making data more secure and reliable.
4. Hard disk format conversion: When you connect a new hard disk, it usually needs to be formatted into a specific file system for use on the Linux system. By mounting the hard disk, you can select a suitable file system for the hard disk and perform format conversion.
It should be noted that mounting a hard disk requires a series of operations in the Linux system, such as partitioning, formatting, and device file association. These operations need to be performed as root or a user with appropriate privileges. Also, after mounting the hard disk, you need to automatically mount it at system startup so that it is still available after each reboot.
