I currently have a 6TB mirror and thinking of getting some large WD disks to put into unit.
How does one go about changing the drive so the data is coppied from existing drive to the new inserted drive. ?
(off course this will have to be done one at a time so matched pair are eventually in place).
I would also want to delete the data off the older smaller drives as well if possible using the mirror.
I use raid 1 mode.
