Difference in bdf output

[T Jose]

Hello,
In my bdf out put it shows
Filesystem kbytes used avail %
/dev/vg00/lvol3 3145728 2100504 1037128 67% /
When I add used and avail space, it is not matching with the kbytes

Can any body say what is this difference?

This is probably caused by some rounding...
2100504 + 1037128 = 3137632, which is close enough to 3145728

Another causes could be fragmentation of the filesystem or space reservation for the root user.
