File System Used space increasing in a different file system

Hi,

I have  problem with two mountpoints / & /opt/JNPRsbr  ,  when I am creating any file inside /opt/JNPRsbr  it is consuming space from / .

For example if I am creating 1GB at /opt/JNPRsbr , then the space used for / & /opt/JNPRsbr is increased of 1GB.

There is no overlapping blocks found for the disk slices.
