Hi im new to freenas and looking for some advice. I recently had my prime nas drive go down (wd my book live) and was lucky to get my data of it. that sparked a search for something better and found freenas now ive had to make to from parts i already had i know its not advised but im hoping to add and upgrade as i go. im only gona use it for tasks like ftp, cifs music and movie server for xbmc 1 or 2 clients max so i dont need a mega nas realy. ok now for the question. I have a box with 2 hdd 1 500gb for torents 1TB hdd for my shares and personal files photos docs and the like I would like to add another 1tb hdd to set up as raid so i have some fall back if things go wrong but only for the 1tb shares disk. (if the torents one dies i can live with that) so is it pos to add a disk and setup raid and not have to backup all the existing data no the drive. thanks.
