NFS server mounting different disks on same volume.
by witchkinkofangmar from LinuxQuestions.org on (#5A5A7)
My NFS server is mounting different disks/paths to the same location. If I touch a file from the client in /mount1, it also shows up in /mount2, which is a different disk. They are showing up on the client like this:
