This article mainly shows you "what to do when you encounter device is busy in Linux", which is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn this article "what to do when you encounter device is busy in Linux".

"device is busy" is often encountered when Linux manages umount devices, if umount a file system encounters this situation, and you are not in the directory you need to unmount. Then it is likely that a user or process is using that directory.

# umount / mnt

Umount: / mnt: device is busy

Umount: / mnt: device is busy

Then you must use the fuser command to view the owner of the process ID and the process, such as:

# fuser-mu / mnt

/ mnt: 25781c (root)

# kill-9 25781

# umount / mnt

In a case like this, it means that rhythmbox users are using that directory. You can then use fuser-ck / dev/sdc1 to kill the process.

# fuser-m / dev/sdc1

/ dev/sdc1: 538

# ps auxw | grep 538

If all these efforts do not work, after killing the process, you may need to add the-f-l parameter at this time to force unloading

# umount-f-l / mnt

NOTE:
