I'm running a 9.10 system with 4 * 3TB drives in a RAIDZ2 configuration, so one drive is parity, giving me 9TB for storage. The box boots from a small SSD separate from the main drive cluster. It's been rock-stable for a couple of years.
I am thinking about expanding its capacity and am wondering whether I can achieve this by replacing each existing drive with a larger model, allowing the array to rebuild, then replacing another drive, and so on. Will I ultimately end up with the full capacity of each new drive, is there some additional step I will need to take, or will I simply end up with the same capacity in the new configuration along with a whole bunch of unused and inaccessible space?
If the latter, should I simply back up the entire NAS, replace all the drives, and then recreate the volumes and reload from the backup? That will be a very lengthy and painful process, although it will achieve my objective.
