RN104 has 3 1tb drives, but only 1tb of usable same

Based on the space calculator tool I expect to have 2 gb? Restarting the machine makes the drive green for a while but eventually it goes back off again.  I've tried pulling and reinserting the drive while it was powered on.  I initially started with the 2 1 terabyte drives earlier this week, and added another 1 tb drive a couple days after but I haven't been able to get it to expand with more space yet.

After rebooting, it will resync for a while then the third drive will go gray again:

I can provide logs, but I'm not sure if there is any personally identfiable info in them?  Anyone know if they are safe to post publicy to a site like mediafire? 

I do have some experience with linux systems, and I may be able to do some further debugging later this weekend once I figure out how to get ssh access to the system.

Thanks to anyone who spends time helping me with this!!

You email logs directly to netgear - see the instructions here for the address: http://kb.netgear.com/app/answers/detail/a_id/21543/~/how-do-i-send-all-logs-to-a-readynas-community...

Your NAS is using triple RAID-1 - which is it not supposed to do when using XRAID (which you are).

thank you @StephenB

Do you have a backup?

One of your existing disks has an increasing ATA error count. That may be why the disk failed to be added to the array.

Currently backing everything up to the seagate drive now.  Going to buy a couple larger drives and try again.

I factory reset the nas after backing everything up.  Afterward, it detected and synced correctly, adding another terabyte to my total storage.
