I'm not sure I entirely follow. However, if you can mount three 
filesystems, you can do userland raid. What those three filesystems are 
doesn't really matter. They could be NFS mounts, RAID arrays, external 
hard drives, whatever you want.

So if you can arrange to have three filesystems which don't live on the 
same physical hardware, the answer is yes. If they do live on the same 
physical hardware, then there's hardly any point.

Which OS is this? What errors do you get?
