Hi,

The following df -h & lvdisplay shows the discrpancy..What could be
the reson? I am referring to the discrepancy between LV Size in
lvdisplay &  total size df -h output of the corresponding file
system.

That just appears to be normal file system overheads. All file systems
use some of the total space available on a device for storing internal
structures and data (the file system's metadata). You'll see this with
any block device type, e.g. with a 64M USB key:

# df -h /mnt
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdc1              61M  5.3M   53M  10% /mnt

Bryn.
