ReadyNAS NVX Drive failure and replacement options
I have an NVX with 4x 2TB Seagate drives, configured as a single volume using X-RAID2. It reports Online, X-RAID2, 4 disks, 37% of 5548 GB used. Earlier today I got "
| Thu Sep 1 00:01:42 MDT 2016 | Disk failure detected. |
Following a power supply problem a few months ago I acquired a 2nd NVX to use as backup. I has 4x 1TB Seagate drives. It's so far unused. By Coincidence today amazon delivered 4x 2TB Seagate drives for the backup NVX and I was going to set-up rsync to backup one to the other.
So, short term I can take one of the proposed backup drives and plug it into the primary and buy another 2TB drive.
Alternatively, since I don't need the full 5TB capacity, it occurs to me I could ut a 1TB drive in the primary NVX; then build the backup NVX with 1x 1TB and 3x 2TB and be left with a spare 3x 1TB and 1x 2TB drive ready for future drive failure.
Make sense or am I missing something important?
Both NVX are already running the latest/last RAIDiator-x86 Version: 4.2.28

That is correct.

The question is, does that give me enough capacity to rsync my primary over at say 60% capacity?
The primary NAS will have 6 TB capacity, and the backup will have 5 TB (note FrontView will show less, since it displays GiB units (1024*1024*1024 bytes instead of 1000*1000*1000).
Not completely sure if I understand the question, but if the primary is ~60% full, then the backup would be about ~75% full.

Hmm, so I've been reading http://www.rnasguide.com/2011/06/22/what-to-do-before-expanding-your-readynas-volume/
