concept of mount point
Hi All
I Know it is a really basic and stupid question perhaps...But I am going bonkers..
I have following valid paths in my unix system:
1. /opt/cdedev/informatica/InfSrv/app/bin
2. /vikas/cdedev/app
Both refer to the same physical location. So if I created one file 'test' in first
path, when i cd to /vikas/cdedev/app and do a ls -ltr, i see the 'test' file
When I do a df -k . on 1 and 2 above, i get the same mount point which is as follows:
/vikas/cdedev/app
Now, I am perhaps taking a long shot, but the most logical reasoning I can give myself is mount point is nothign but actual physical location in hard drive whereas directories are logical pointers to mount points. So 1 and 2 above are logical pointers to the same physical location. In other words, they point to the same mount point.
I might be way off. In any case, can somebody throw some light on following:
a. concept of mount point as well as Unix file system?
b. Is it possible to see which directories refer to one particular mount point by some unix command?
Appreciate it much.

Dear All,
We have two different mount points in Linux NFS one is 15 TB and another one is 15 TB.
Can we club both of the two mount points and club in to a single volume in Linux.
As we need to restore Database in that single volume.
Kindly help us on this.
