[操作疑難] TS-453Pro (4Nos 6TB) Missing of 8TB

I just bought a QNAP TS-453Pro with 4 Nos. 6TB hardisk.

I have set up Raid 5 for the system. Theoretically, I should get 3X6TB= 18TB storage.

But when I look into the storage , it states that there is only 1 DataVol1 with 10.8 TB, this should be 18TB, where is the difference gone?

Or do I have to do something to grab the remaining 8TB?

    Sorry, I am a newbie, so, bear with me if the question seems naive.

睇下有冇未配置空間,Default應該係只配置50%

RAID 5 space ~~ 1 − 1/n = 1 - 1/3 = 2/3 ~~ 12GB (or less for system)

    Where to look for that "Spare Capacity"?

    Right! Out of the four disk: 3 are listed as DATA, while the last one is listed as FREE. That's why it only has 10.8TB as you have calculated.

Does that mean that when the storage increases, it will automatically use the fourth one?

You should see disk management or storage management .
I think one of four disk is not available, it was because 10.8 TB is  3-1 =
6TB =6.0TB /9  X2 =10.8TB

You'd better to post the image of storage manager for solving problem.

Use "Expand Volume" to include the free space.
