problem stockage

Hello,
I have an F4-424 Pro NAS in TRAID with 3 drives: 12 TB - 8 TB - 1 TB, and I decided to replace the 1 TB drive with a 6 TB drive.
When I removed the 1 TB drive, the NAS made a noise, so I inserted the new 6 TB drive, and the NAS reported: RAID problem. I then went to > Modify > and it only offered me the option to repair the RAID, while the rest was grayed out.
I repaired it, but I noticed that in the end, the volume did not increase. I tried to follow the tutorial to do it manually (PUTTY) , but nothing changed. Do you know why?

Probably about right. You can check the likely effect of HDD changes in raid {T and others} using the raid calculator on the TM support website.

According to the calculator, I should have 14 TB and not 8 TB.

Hope someone can explain that, I can't.
