disk space

when i check
/export directory of my machine gets filled up (85%) i removed some old logs. but after cleaning df -k command still shows that /export is still 85% full.

Is there a way to force df to reflect actual free space without rebooting? My machine is a production one and can't afford down time. My OS is Red Hat 6.2

using lsof to find out what is keeping the file open could help. It will report the correct amount free when the last file handle is closed, I believe.

It's better to truncate log files than delete them. Deleting them won't actually free them until any handles to them are closed, but truncating them will free the space. You can do this like echo > /path/to/logfile
