what is the filesystem you are using there?
mount | grep /u01
if the filesystem is OCFS2, in old versions there is a bug in some cases the space won't be released and will fell undersomething called orphan files.
if that's the ase, you should stop the services, umount the filesystem on alll the nodes on the cluster, and run fsck
If the filesystem is not ocfs2, then maybe you still have process using those files/directories and the data is marked as deleted, but will be released once those process finish.
as root run
lsof | grep delete
and check if there are files marked as deleted under the path that match where this monitoring tool was.
If yes, then try to kill those process and check the size again.
If none of the 2 cases address your problem, please provide more information
