I have a WD Mybook NAS that is SAMBA and NFS compatible. Everything works an absolute dream in Ubuntu 13.04. I mount the drive on bootup using an entry in FSTAB.
I am about to run out of space on my NAS and a double sized NAS is a bit expensive. A cheaper option could be to buy an identical sized NAS, and use two drives. I could add a 2nd entry in FSTAB and have two directories mapped to my two NASs. However.... could I mount BOTH the drives onto a single directory so the two NASs would appear as one single mapped/mounted directory?
