I setup a small 1.5TB 3 drive RAID5 using some old 750GB drives I had laying around on an 1880 to use as a server root drive for a project I have but have since decided that 1.5TB is very unlikely to cut it after all and would like to expand but don't want to waste money and bay space on more 750's when 2TBs are so cheap, so I was wanting to do an inplace upgrade. Problem is looking around the web GUI I don't really see a graceful way to do this other than set 3 2TB drives as hot spares, crank up background priority, yank a 750, wait for rebuild, yank a 750, wait for rebuild, yank a 750, wait for rebuild, expand the volume. Pretty sure this will get me the desired results even if it takes a bit, just wondering if I've missed a bit more graceful way of doing this.
