System mount errors are usually caused by parameter errors in / etc/fstab.

Environment: Red Hat 7.2

Simulated fault

Change / etc/fstab from xfs to ext4 under normal conditions

Restart the system and reproduce the failure.

When you encounter this kind of error, it is usually caused by the parameter error in / etc/fstab. You can check the file system first, and then check the mount point and other information.

Solution method

Enter the root password and enter the command line mode. If you forget the root password, enter the single-user mode to reset the password.

Before troubleshooting, let's introduce the blkid command: the blkid command is a command-line tool that displays information about available block devices. It can identify the type of content of a block device (such as file system, exchange) and obtain attributes (such as tokens and key-value pairs) from the metadata of the content (such as volume labels or UUID fields). It has two main functions: searching for a device with a specified key-value pair, or displaying key-value pairs for one or more devices.

By comparison, it is found that the ext4 in / etc/fstab and / boot should be changed to xfs.

Restart check

The system has started normally
