Describe Linux fstab Parameters

In today's society, computers are becoming more and more popular. We use computers, but do we know how computers work? An operating system is essential to a computer. However, Linux is developing very rapidly and is catching up with Microsoft. Here we will introduce the knowledge of Linux, so that you can learn how to use Linux. Today, I will talk about the Linux fstab parameter. I hope you will remember Linux fstab.

Linux fstab stores important partition-related information. Each row is a partition record, and each row can be divided into six parts, the following uses/dev/hda7/ext2 defaults 1 as an example to describe one by one:

Fstab stores important information related to partitions. Each row is a partition record, and each row can be divided into six parts, the following uses/dev/hda7/ext2 defaults 1 as an example to describe one by one:

1. The first is the physical location of the storage device you want to mount, such as hdb or/dev/hda7 in the above example.

2. The second item is the directory to which you want to add it, such as/home or/in the above example. This is the Mount point prompted during installation.

3. the third item is the so-called local filesystem, which contains the following formats: ext, ext2, msdos, iso9660, nfs, swap, etc., or ext2, see/prco/filesystems.

4. the fourth item is the status you want to set during the mount, such as ro read-only.) or the defaults in the above example includes other parameters such as rw, suid, exec, auto, nouser, and async ), see mount nfs 」.

5. The fifth item is to provide the DUMP function. It indicates whether the BACKUP flag is required during system DUMP. The value is 0.

6. the sixth item is to set whether the filesystem performs the check action at startup. Except for the root filesystem, the required check value is 1, and the other items can be set as needed. The internal value is 0.

After reading this article, you must have gained a lot from Linux fstab. I hope this article will teach you more things.
