Can't find the storage capacity I should have
I bought several month ago a ready Nas and Two DD of 6 TB.
Both seem to work fine (I can find ther with a green light on the admin page with the right capacity.
But the total capacity of the storage is 6TB and not the 12 I need. Can you please help me !
Other question :
I bought another DD of 4TB. It's recognized but is still grey on the admin page. How can I make it work with the other ones.
Thank you !

I presume you're running in X-RAID mode. So you have a RAID1 build with both 6TB HDD. So the equivalent of one HDD for capacity, and the equivalent of one HDD as mirror.
If you add a 4TB HDD, X-RAID cannot expand your existing volume to RAID5 because the HDD is too small.
If you need more information about X-RAID, please refer to the user manual (see NETGEAR support website).
If you wish to have a 12TB volume and also have redundancy, you need a total of 3 HDDs of 6TB.
If you don't care about redundancy, you could turn off X-RAID (to go to Flex-RAID), destroy the volume (and lose all its content), and create a JBOD volume on the two 6TB, but you'll have no redundancy (it any HDD fail, the whole volume is dead).
If having a single volume isn't an obligation, you could have separate two JBOD volumes (one per 6TB HDD), but still no redundancy.
Look at this thread, redundancy is important: https://community.netgear.com/t5/Using-your-ReadyNAS/Failed-disk-on-readynas-RN104-JBOD/td-p/1083480
Hi KARREV,
Welcome to the community!
It is possible that your current RAID configuration is RAID-1 (mirror) that's why your total volume capacity is just half of what you're expecting. If you want to maximize the total capacity of both drives, you need to destroy the volume and build a new volume with Flex-RAID 0 or JBOD. Lastly, can you confirm if the X-RAID button under System -> Volumes is ticked?
Kind regards,

NETGEAR Community TeamHi, I am using X raid and I have 4X 4TB hard disk installed. Is it normal that I could only see10.9 TB in total?
I was wondering if I would like to expand the total 16 TB to 24 TB, what is the best way to do it?
Thank you very much
Keith
