I would say that is correct given that you have dual redundancy and 3 750 gb drives, the 2 2tb drives won't add any more capacity than if they had also been 750gb drives. With dual redundancy you would need to add 4 disks with increased capacity to vertically expand. Obviously you can't do this. Can you afford to get 2 ( or 3) more 2tb drives?
Why is this volume not 11GB (17 GB of drives - 6GB of redundancy) If it never see's more than 746 GB of space that seems a waste of money to use 3TB or 2TB drives How do I get more space while still using 2 Disk redundancy because it's more like 5 Disks of redundancy not two.
Hi. I see. Strange. I assume you factory defaulted with the latest firmware. Don't take this the wrong way, but are you certain your 3 tb drives are 3 tb, not 750 gb?

The disk models shown are certainly 3 TB. They would show as 750 GB if he was using 4.2.15 or earlier firmware. I think that is the most likely explanation.
I had assumed the OP would have had latest firmware as this is his 3rd Ultra 6 and he has posted previously suggesting he is aware of the need to use latest firmware. Perhaps I'm wrong
I did my 4th factory reset and resync Should be Total Drives 15.3 GB - 5.4 GB Redundant space = 9.9 GB What Ready Nas is doing 15.3GB - 7.4 GB of Redundant space = 7.9 Available space Why is READYNAS not seeing 3TB drives? Nothing better than 2TB drives
It would create the layer with 2TB per disk and then once that's all synced up sector-by-sector then expand to add a layer using the remaining 1TB on the 3TB disks.
OK 5th Factory reset was a charm - it took 28 hours to resync! I added added a 6th 3TB drive. anything less it would expand out to the proser volume size. This did not happen with Single disk redundancy. It took a total of 124 hours to get it resyc'd and working fine. I just found it confusing that waiting 20 hours then waiting another 8 hours for the volume expansion and it still failed to expand properly when I had 5 disks in. I still needed to add a 6th disk. If this is normal then it should be clear in the manual "If using dual redundancy disks you MUST have ALL drives the same size" If this is not normal then it must be a firmware bug. Anyway I am not being paid enough to beta test 8-)
