Can I upgrade my drives to 2 or 3 TB?
I currently have a ReadNas Duo with two 500 GB SATA drives. Can I upgrade these drives to 2 or 3 TB each? I guess I mean is there a limit on the size of a drive that you can use in the Duo? I ...
There are two models of duo - v1 and v2. If you purchased in 2008, than you have a duo v1. There's a guide here: http://www.rnasguide.com/2012/01/09/how ... -or-nv-v2/
The duo v1 supports 2 TB drives (but not 3 TB). You will need at least 4.1.7 firmware to use 2 TB drives - of course current firmware is better.
For best performance you want 4K sector alignment of the partitions. If you don't have that already (and you likely don't) you should do a factory reset, and rebuild the RAID array from scratch. You might as well do that with the new drives in place. That is.
(a) update firmware
(b) make a backup and save config
(c) shut down NAS, remove drives
(d) install both new drives and power up (this will do a factory install)
(e) reinstall addons (order of this step matters!)
(f) restore configuration
(g) reload data from backup.
You can check to see if you have 4K alignment using this guide: http://www.rnasguide.com/2011/06/22/why ... -readynas/
If you already have 4K sector alignment and are running 4.1.7 or later, then hot-installing the drives (as you outline) will work.
