Workarounds for Du and DF inconsistencies

Df:disk free, which counts the disks that are idle in the current system
Du:disk usage, which counts the idle disk being used.
If a file is deleted and the process using the file is not restarted, then there is a case of DF and du inconsistencies.

Workaround:
1. Run Command lsof | grep deleted lists all files that have been deleted but are still occupied by the process
2. Kill the process that occupies the deleted file.
