Sometimes df –h command not updating the actual space details even after deleting files or folders
To solve this issue we need to follow the below steps.
Run the command,
# lsof | grep deleted
This will show the list of files that are deleted but still in use by a running process.
Kill the listed processes using the command,
# kill -9 pid
Here we need to replace the pid with the listed process ids.
Then verify the disk space again df command
# df -h
