[Samba] Adding Nested Partitions To A Mount Point

[Carter Campbell]

I was wondering if anyone can tell me if it is possible to mount a drive 
(single partition) to a nested directory on an existing Samba mount 
point and have the entire structure considered one drive?

The situation is this.  I have a large drive mounted to a share called 
"/pub".  This has been identified as my Samba mount point and all works 
as it should.  What I would like to do is add a subdirectory to the 
drive mounted to the "/pub" share point and mount an additional drive to 
that. I would like to be able to have this second drive treated as an 
extention of the original disk, under Samba.  This would mean that the 
capacity of the second drive would be pooled with the first drive, on 
which it is mounted.

For example:
I have a 200GB hard drive mounted to the directory "/pub".  I would like 
to add an additional 60GB drive to this.  Can I create a directory on 
the 200GB drive called "/pub/temp" and mount the 60GB drive to that 
mount point?  Then be able to have Samba consider the whole mess as a 
single 260GB drive?

I have already tried this (with my limited knowledge) and all that seems 
to happen is that the Samba identifed disk capacity size remains at the 
200GB mark.  The additional 60GB isn't recognized.

Would this be possible, or am I blowing smoke out my lower orifice?  If 
it is possible, how would I do this?  Is there any documentation that 
would explain something like this somewhere?  What would this be called 
if I were to look for it (I haven't the slightest idea how to start 
searching for such a thing)?

Thanks to all in advance.
