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

showmount

SHOWMOUNT(8)						    BSD System Manager's Manual 					      SHOWMOUNT(8)

NAME

     showmount -- show remote nfs mounts on host

SYNOPSIS

     showmount [-a | -d] [-e] [-1] [-3] [host]

DESCRIPTION

     The showmount utility shows status information about the NFS server on host.  By default it prints the names of all hosts that have NFS file
     systems mounted on the host.  See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version
     3 Protocol Specification, Appendix I, for a detailed description of the protocol.

     The following options are available:

     -a      List all mount points in the form:
		   host:dirpath.

     -d      List directory paths of mount points instead of hosts.

     -e      Show the host's exports list.

     -1      Use mount protocol Version 1, compatible with legacy servers.

     -3      Ignored for backwards compatibility.

SEE ALSO

     mount(8), mount_nfs(8), mountd(8)

HISTORY

     The showmount utility first appeared in 4.4BSD.

BUGS

     The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless.  The showmount utility will
     only display the information as accurately as the mount daemon reports it.
