Thank you for the excellent responses.<br><br>Interestingly, when I looked in the directory listing of /home2, there was only one userhome there, and /home had the rest (as I expected).<br><br>I have just recently run across this "bind mounting" you referred to in a set of instructions for setting up NFS v4 on our team's machines.<br>

William, I would not be that sure about that. I've just tried such double-mount on my Debian system and it has mounted silently, with not even a single warning message.<br>

That's because 2 different concepts are being confused here. I'll cover them seperately. Anton did go in to this a bit but I think it will help to cover it like this:<br>
<br>
Q1) Can one filesystem be mounted multiple times on a single system?<br>
<br>
A1) On modern Linux systems yes. Not all modern OSes support this feature. On Linux this is known as 'bind mounting'.<br>
<br>
Q2) Can one filesystem be mounted on two different directly connected systems?<br>
<br>
A2) Read-only, yes. For write access the filesystem needs to be a 'clustered filesystem'. I covered this in more detail in another post.<div class="im"><br>
<br>
Cheers,<br>
