I'm sure this has been answered before but wasn't having much luck with my searches. My pool is little over 7tb and I only have 115gb of space left. Most of the data is duplicated. I want to replace 2 of the 1.5tb drives with 3tb drives. I do not have any available space on the motherboard to add the drives directly. Could I add the new drives via USB or esata, add it to the pool? At this point I could select the drives I want to remove and there would be enough space to move the data off of them before taking them out. Could I then move the externally connected drive into the case? Would I be better off selecting a drive to remove and having the data just not be duplicated while it is removed and then add the larger drive?
I guess what I'm asking is what is the best way to increase the space of my pool in this situation? Thanks
