NFS mount issue

we are facing a weird NFS mount issue on one of the linux host , a NFS volume of 2.4TB is mounted in the linux host , but df only reports 131g , which exactly matches rootfilesytem size

Code:
nfs mount
filer_filer1:/vol/bug_test/q0
                      131G  116G  8.5G  94% /nas/bug_test
root file system
/dev/mapper/VolGroup00-LogVol00
                      131G  116G  8.5G  94% /

any size change is rootfilesystem changes the nfs filesystem size too

if i mount the same nfs filesystem to a diff mount point , then it reflects correct size and the contents are all diff

filer_filer1:/vol/bug_test/q0
2.4T 88G 2.3T 4% /nas/test


can anyone explain this behaviour ? , i haven't tried umounting and remounting the /nas/bug_test mount yet

Is the contents of /nas/bug_test the one from the NFS server?
Maybe an evil guy did a
Code:
umount -n /nas/bug_test

so it's umounted by the kernel but the mount command still shows it.

content of /nas/bug_test is not present in NFS server
