The issue of Space not released after Linux deleted large files

Problem Description:

Disk 100% , after deleting large files, df-h found disk space not released

Workaround:

The problem is that in Linux systems, deleting files via RM or File Manager will unlink the file system from the directory structure (unlink). However, if the file is open (a process is in use), the process will still be able to read the file and disk space is always occupied.

# lsof |grep deleted

#kill xxx Delete a process that occupies a file

#df-H View disk space again
