Can't expand drives on TS419P+

[mnhim001]

Can someone please help me with expanding my QNAP TS-419P+. I have a total of 10TB in my drives, but it only sees 2.7TB total size. I have my QNAP setup for RAID5. Did I do something wrong?

Disk1: 3GB
Disk2: 1GB
Disk3: 3GB
Disk4: 3GB

Before it became 10TB, it was only a 5TB system. Seems like it didn't take the new drives and expanded them. The drives do get recognized in Volume Management. I go to RAID management and click expand, in the next screen my expand is grayed out. The only available buttons are Change and the Back button.

The 1 GB drive in sot #2 is the show-stopper here. In a real RAID, all disk must have the same size. Any additional space can't be used. I don't think you want to make it a 4 * 1 TB RAID.

Swap move the 1 TB HDD to slot 4, and the 3 TB to slsot #2. Then you can expand to the three 3 TB HDD, making the RAID span HDD 1...3 for now.

Use the 1 TB drive as a single HDD volume, or replace it budget and time permitting with a fourth 3 TB drive, so you can expand the RAID again to span HDD 1..4 then.

This is effectively explained in the RAID Management section of the QNAP Turbo NAS User Manual.
