I was trying to clean up some disk space and deleted a huge log file that apparently is not set up to roll correctly. It is used by syslog-ng. I could have sworn I stopped syslog-ng before I deleted it, but looking through 'history' I apparently didn't.
End result is the disk space availble according to 'df -h' is the same as it was before.
I did a du -sh on the partition and manually added up all the numbers listed there and it is definitely well under what is being reported as used.
Doing a 'service restart syslog-ng' did not re claim the space. I am not an expert on sys admin stuff and have seen conflicting information in my searching some saying that should have been fine to re-claim the space, but people reporting they need to re-boot to re-claim space.
Is there a way to re-claim this space with out a reboot? There are no files in /tmp.
I'd like to think there is some way that this can be done I just am not sure. Some sort of tool I can run. Just an fyi I don't have a gui front end to this system. It would have to be a command line tool.
