NEWB 2TB + 1TB....? what will happen>?
I have just put one 2TB drive into my NV+2 and its working great, i have realized i have another 1TB sitting about doing nothing and also 2 x 500GB's what would happen if i was to put these into the ...
If you have 2 3TB drives, and 1 2TB drive, then the total volume would be 5 TB.
You generally don't need to worry about the layering, the quick way to work out the total storage is to pretend the largest drive isn't there, and total up the others.
However what you'd have initially is one 3x2TB layer (2 TB from each drive) and one 2x1TB layer (the 1 TB remaining on each of the 2 TB drives). All this looks like one volume to the users.
If you then replace the 2 TB drive with a 3 TB drive, the RAID array is restriped into a single 3x3TB layer. Adding the last 3 TB results in a 4x3TB layer.
