How can Linux determine if a mounted partition is successful?

In a Linux system, there are several methods that can be used to determine if a partition has been successfully mounted.

1. By using the mount command, you can check all currently mounted partitions and their corresponding mount points in the system. If you find the partition you want to check in the list and the mount point matches your expectations, then you can confirm the successful mounting of the partition.
2. To verify the successful mounting of a partition, use the df command to display information about all currently mounted file systems, including their mount points and remaining space. Check if the output includes the partition you want to verify, and ensure that the mount point and space information match your expectations.
3. Check if the files under the mount point are visible: go to the directory where the mount point is located, use the ls command to see if the files in the mounted partition can be listed. If you can see the expected files or directories, then the mounting partition is successful.
4. Check the /etc/fstab file: This is the file used in Linux systems to configure mounting points. Open the /etc/fstab file and make sure there is a mounting point configuration corresponding to the partition you want to check, and that the configuration information is correct. If the configuration is correct, then you can determine that the partition has been successfully mounted.
5. Check the system logs by using the dmesg command or viewing log files such as /var/log/messages or /var/log/syslog to search for relevant information related to the partition you want to check. If you can find logs indicating successful mounting of the partition, then you can confirm the partition has been successfully mounted.

Please note that the above method is only applicable when the mounting operation is successful. If the partition fails to mount, you need to check the error message to determine the cause of the failure.
