An alert was triggered because a server root directory was recently full.

Enter the root directory:cd/ Run the du -sh * command to view the size of each folder in the root directoryCopy the code

Then, run the mv and rm commands to back up and delete files after repeating the du -sh * operation

Later still have a problem: after the delete command df and du appear inconsistent results, namely the delete operation was not completed The solution: use lsof | grep does look at it

lsof | grep deleted
Copy the code

In this case, run the kill -9 command to kill the process. The file is deleted successfully. Df and du are the same.
