[Linux-cluster] Multiple Roots

[isplist at logicore.net]

This might be a long shot but... is there a way of taking a single GFS 
filesystem and creating multiple roots that only certain machines in the 
cluster will see?

I'm almost sure I read somewhere that there is a way to do this. The reason 
is, 

I keep having to separate my storage up and I would much rather maintain one 
large storage array (contiguous) and dole out the space as needed to the 
various applications. 

That is an inherent part of fibre channel storage which is what I'm using so 
assume it can be done with GFS.

If I didn't explain some part correctly, by all means, just ask.

Thanks much for any input on this.
