The problem is that adding disks is harder than one would like as the computer only has 8 sata ports. Is it viable to do the following to upgrade one of the disks? A) Take array offline B) DD the contents of one of the 750G drives to a new 3T drive C) Remove the 750G from the system D) btrfs scan E) Mount array F) Run a balance I know that not physically removing the old copy of the drive will cause massive issues, but if I do that everything should be fine right? -- Gareth Pye - chatterofjudges.mtgmelb.com Level 2 MTG Judge, Melbourne, Australia
