I'm not as confident as other's with the shell side of things, so if it's possible (even if slower) to do this using the GUI (or very minimal shell work), that would be great!
I'm currently using a RAID5 setup, which is getting pretty full. I have 6x 2TB drive. I am looking to replace them with 4x 5TB drives. Ideally, I don't want to have to take all the data off the RAID (because I don't have a 10TB external drive to put it all on). I've had a look around, but haven't been able to answer this scenario/question yet (or get a trustworthy answer from a pro). Not sure if it's even possible? If not, easiest solution/suggestion would be appreciated.
