Hello,
I have a linux systems with RHEL-4 installed with seven partitions, SATA Harddisk size is 160GB , My /usr becomes 95%, When I checked using `df -k` , SoI deleted Some logs from there and freed Space upto 35 GB, Now when I give `df -k`. Its Still showing the old space status. How do I get the right status from `df -k` without rebooting thet system.
I tried by giving sync, and even remounted that by giving foll command
mount -o remount /usr
Still , Its showing the old status, but When I check using
`du -sh` , it shows the right status, Why `df -k` is not giving the right status

It is possible that there are some unlinked files held by running processes (which would explain why the space reported becomes fine after a reboot). Run the below:

ls -ld /proc/*/fd/* 2>&1 | fgrep '(deleted)'

It might show some PID's which are holding to large files that you have deleted. Restart those processes and df should report the correct space.

But Is their any command,to update so. This happens also when we delete some files which are not linked to any running processes e.g Old backups or some files which are not being used by any other processes like some avi video files or audio files.
