ReadyNAS Pro with 6 2TB drives to 6 3TB with Dual Redun
Hello, new here, many apologies if I missed this with an earlier post.
I currently have a Readnas pro with 6 - 2tb WD black caviars in my set up now running single redundancy and running 4.2.19.
I want to expand my system with 6 - 3tb drives and while I'm at it, go to dual redundancy.
Questions:
1) I'm gathering, from lurking around here, that this is not possible to expand and go to dual without a system reset?
2) If I only had 5 drives, then I could have gone to dual, then expanded.
3) So what I think my ONLY choice is to achieve both is to, back up all data with verification, save my config, do a system reset via boot menu, pull my old drives out, put in new ones and reboot again with new drives. After lengthy rebuild, restore config and then data. Does that sound right? (not totally sure of my order of system reset and pulling out old drives, which is first?
I was hoping there was an easier way, but I'm thinking when I put in the new drives just put in 5 and tell system at that point to go Dual Redundant? does that work? and if so, I'm thinking that restoring the config is out at that point, due to it being a 6 drive config? (not really the end of the world since I would have to restore everything anyway.)
--------------
Of course, the easiest thing is to replace the drives one at a time, waiting for full resync/expand and stay single redundant.
Ideas or suggestions?
Thanks so much in advance!

3) Power down the ReadyNAS, remove old drives (label order), put new drives in and do factory default
You can restore the config. The config is not storing the number of disks but rather your configuration of the OS. For dual-redundancy you'll need at least four disks installed.
1. Power down
2. Put new drives in
3. Do a factory default using the boot menu (http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu)
4. Discover NAS using RAIDar (http://www.readynas.com/downloads)
5. Click Setup
6. Choose X-RAID2, tick dual-redundancy option and confirm your choice. - Thanks much for the quick and great reply!!!
You mention label disk order when pulling out old drives. Is this in case I want to go back to the old set up, obviously needing to keep drives in their original RAID physical order?
Right now I'm using 8 tb of my 9+ tb. What will be the size of with dual Redundancy with (3 Tb drives) with 4 drives? 5 drives? and 6 drives?
Thanks again, great Forum! camelxx wrote:

Yes. If all disks are fine the order might not matter but best to keep the ordering the same.camelxx wrote:

Very roughly:
4x3TB drives about 5.4TB
5x3TB drives around 8TB
With 6x3TB drives it'd be around 11TB.
Remember that 1TB = 1024^4 bytes whereas disk manufacturer says 1TB = 1000^4 bytes. So a so-called "3TB" disk actually has a capacity less than 3TB as far as the NAS is concerned. There are of course overheads as well.
Taking a look at X-RAID2 dual-redundancy expansion paths may also help (note this was written before there was the option to convert a single-redundant volume to a dual-redundant one: http://support.netgear.com/app/answers/detail/a_id/19044/~/converting-and-xraid2-system-to-dual-redundancy)
