no changes after deleting files
 

Hi ,

I have deleted some log files because of space crunch and after removed I still see the same percentage of space as how it was earlier before removal. So can you suggest what could be the reason and how to fix it out?

Thanks

my questions , even after removal of log file, I see the same filesize in the var , no changes has been taken effect with

Removed a log file or cleared it?

So how did you remove it?

If you wanted to clear a file:
Check the file size before and after.

Try looking for zero size files:

I just make a script and clear the log after review.

For log files, you should really use the logrotate tool http://linux.die.net/man/8/logrotate, see /etc/logrotate.d (dir).

FYI, if a process has a file open, the the disk space is not returned after deletion until the file is released http://linux.die.net/man/2/unlink i.e. the file just becomes invisible to ls, find cmds etc.
You shouldn't normally delete an open file anyway; see lsof http://linux.die.net/man/8/lsof fuser http://linux.die.net/man/1/fuser

You can shorten that to

Thanks TobiSGD, I'll add that to my script!

Exactly. From the sounds of this problem, you may have just unlinked a file that is still being written to.

Try:
(That is a root prompt. So run it as root.)

Thanks lot!!
