use fuser to check.

Hi,

You can also use lsof to grep for the name of the file that you removed in order to identify the process hanging on to the open file.

You can download lsof from:

Hope this helps. Regards.

If the problem is a large file which is held open by an application you want to remove to reclaim space, you can also flush the contents of the file.

The result is an empty file, still held open by the application.

You will of course lose all information in the file. You have to evaluate if this is a problem for the (still running) application.

One command for flushing the file is:

> filename

Hi,

I had the similar problem and helped me only remount of the concerned fs. Anyway it is better than reboot.
