Whoaa!!! Slow down there, pardner! You'll want to select a reasonable chunk of that 4 TB, perhaps all of it, as the new /home partition. Mount it temporarily, then *backup the contents of /home to the new mountpoint*. When ready, announce some downtime, get people off the system, move aside /home, do a finaly mirroring, verify that nothing is writing to the old /home with "lsof", then remount the new partition as /home. Keep the old /home around, say as "/home.old", for a while foe people to settle in. If you can schedule time, try to do this in single user mode, it's a lot safer. Simply slapping new disk space on top of your old /home will hide the old /home directories, and you won't be able to *access* it to do copies. Worse, processes can still be writing to the old files *under* your new mount point, and chaos can ensue without some elementary caution.
