I want to replace one of the drives in my EX4 with a larger one, set up the exact same shares as currently exist, move the data from the current drive (JBOD) onto the new one and have everything going just as before, but with an extra 2TB. I have a few questions along the way:
What will the EX4 do if it’s turned on and one of the drives its expecting just isn’t there? Should I insert the new drive before or after power on?
Will a live ubuntu distribution be able to read all the data from the outgoing drive to copy back across? Or better still, if I put it into a USB3 enclosure, will the EX4 itself be able to read all the data if this was plugged into the back?
Where on the EX4 are things like SQL databases, installed apps, etc. stored? Can I back these up in any way?
