I have given a share in Server-A.

When i issue showmount -a from Server-A, it shows that Server-B has
mounted my share.

Say i want to be in Server-A and umount the shared mount point that
Server-B is using.

I know that I can restart the nfs service on Server-A. But the problem
is there are some other shares that are being used on lot of other
servers.

My action should not disturb that.

Any help in this regards would be highly appreciated.

I need the solution ASAP.

Thanx in Advance.

Sweet Regards,
Sangeeta.
