Simple ReadyNAS 6 Pro XRAID2 question
Hello, I have a 6 bay ReadyNAS Pro 6 RNDP6000-200 with 1 WD WD20EFRX 2TB Red drive in it. The drive is almost full, and I want to add some space. I am considering either adding 1 more WD20EFRX,...

TB stands for terabyte; TiB stands for tebibyte. https://en.wikipedia.org/wiki/Tebibyte The NAS reports TiB, but mislabels it as TB.
You have 14 TB, which is the same as 12.7 TiB.
The conversion formula is
14 TB = 14 * (1000/1024) * (1000/1024)* (1000/1024) * (1000/1024) TiB - which is ~12.7
Having two measures for space is very confusing, but goes back a very long time.

Hello,
My rebuild finished, so I resent my logs.
We are past the 9.99TiB volume size, it now shows 12.7TiB total. However, from the calc, I should have 14TiB? So, I am missing 1.3TiB?
Again, 5 x 3TiB Toshiba ACA300 drives, and 1 x 2TiB WD Red Drive.
Running 6.4.1.
