Yes.

I am thinking no - although  I could be wrong. Where would it keep the 
quota information? GlusterFS prefers to keep all metadata on the file 
system itself rather than keeping a separate store. There is no central 
"how much space is being used for GlusterFS?" query for GlusterFS to 
perform, so there would be no cheap way of figuring out how much was was 
available before allowing a write() operation to complete.

You might be able to look into something like per-user quotas provided 
by your operating system, assuming the GlusterFS users are different 
than the server system users.

I think you should have separate file systems. Putting many things on 
"/" is ok - putting everything on "/" is going to cause you many 
problems. This is one example of such a problem.

Cheers,
