In Linux (CentOS 5.4), how do you force a process to stop locking a file system without killing the process?
I am trying to get my Java Webstart Application, running locally, to eject a CD. I do not have this problem if I am just browsing through the files using a JFileChooser, but once I read the contents of a file, I can no longer eject the CD…even after removing ALL references to any files.
Hitting the eject button will give the error (Title – “Cannot Eject Volume”):
“An application is preventing the volume ‘volume name’ from being ejected”
Thus, my goal is to tell the process to stop targeting the CD-ROM in order to free it up.
Thank you for any help or direction!!
Attempted Fix:
-running the commands:
sudo umount -l /media/Volume_Name //-l Lazy Unmount forces the unmount
sudo eject
Problem:
When a new CD is inserted, it is no longer mounted automatically probably because the process is still “targeting” it.
Assuming that
lsoflists your java application as the only application accessing the file, you might try forcing a garbage collection (using jvisualvm or a similar tool) to see if that frees it up.
