Re: Difference in %Used in "empty" filesystem after reboot

It's not really a lock issue. It's an open file reference. Using lsof, you can
get a list of processes with files open on the filesystem. You could use
something like fuser but it often misses stuff. And if the process with the
open file is important, a blast away killing of the process is probably not a
good choice.
If you can umount the filesystem, no process has any open access to it.

Thanks for the clarification Chris and Mark!



Any way to remove locks and free up space without having to reboot?

File systems that had files deleted but not yet available for the system to use
- once you rebooted any locks that were still on those files were released.

Have a filesystem that is reporting different utilization statistics before and
after reboot.



Filesystem was emptied using rm -r

Command used to obtain statistics was df -k.



Any ideas on why more space is available in the filesystem after reboot?
