I think this should be a simple procedure, but I am asking all the same ...just to be sure. I have a ReadyNAS Duo V2 with the latest firmware (5.3.7). I started out with only 1 WD Red 2TB disk, and later added a Seagate 1TB Barracuda for mirror. All is well and it shows a 1TB capacity. I finally was able to afford another 2TB WD Red disk. I plan to: Shutdown the NAS Remove the 1TB Barracuda. Power up the NAS and see what happens. Shutdown NAS again. Add new 2TH WD Red drive. Power up and wait for re-mirroring. Does this sound correct? I am probably looking too deep into this but it took me so very long to buy the 2nd drive I would hate something going wrong.
sounds most thing is right,but I don't understand why your second 1TB drive would resynced with a 2TB drive,are you sure current volume is redundant and it is running in Xraid mode?
I checked again today. Dashboard says: X-RAID2 (Redundant) capacity 913.4 GB. Info tab has green lights for both 931 GB and 1863 GB drives. I might have done a factory reset, don't remember. When I remove the 1TB Barracuda and insert the new WD Red 2TB I may also do a factory reset. There is not a lot of data on there at this time and I can copy what I need back to the NAS from the Barracuda.
You don't need to shutdown in between. Pop out the 1TB, put the 2TB in that drive tray, and re-insert it. The system is hot-pluggable, power down is not needed to swap drives.
Also, you have a Duo V1, not V2. Ignore the label on the bottom, that should really say V1H2 (version 1, hardware revision 2).
Yes. And the duo would therefore be running XRAID, not X-RAID2.
Note that the barracuda is formatted for the duo (using ext) so you can't read the data on a PC or Mac w/o special tools. You should therefore backup the data to a disk you can read before you hot-swap the new drive.
I apologize; I did not have my facts correct when I did the original post. I incorrectly stated my firmware level. It is 5.3.7 and RAIDar reports it as a Duo V2. I also have a ReadyNAS Duo V1 and THAT One has the 4.1.7 firmware. I must have read the wrong line. To compound my errors; the 1TB drive is (was) in Disk 1 slot. I have just replaced it with the new 2TB WD Red drive and it seems to be re-syncing OK. Sorry for my inaccurate post.
