Missing Large Part of my Storage

[InteLLI]

Now it was a good while ago i installed my freenas and had som problems setting it up getting it to work right. After fiddling around alot i managed to get it working. I have 6x3tb wd red drives in raidz1. I began to transfer over files but after fiddling som more in the settings i couldnt access my files on freenas. read a bunch on the forum and some other places aswell and managed to get it working but lost almost 3tb of drivespace. im totaly green on freenas so i dont know what i did exactly but i think i did something like

- Created a user and set up my drives as raidz-1 with the wizard.
-All worked and i started transfering my mediafiles to the nas.
-Started tampering with other users and tried to configure SMB sharing.
-Changed something and i couldnt access my files anymore.
-In my attempt to find the problem Created a new dataset.
-Managed to get access to that dataset and SMB working.
-Started to transfer files again in to that Dataset.

But that dataset is almost 3tb smaller than what my total was before.

What have i done and what can i do to fix it?


Im running FreeNAS-9.10.2-U2 (e1497f2)
My Server Spec:
Core I7 2600K
Asus maximus IV Extreme
16 Gb DDR3
Radeon 7970
6x3tb WD red drives

The numbers are correct, you aren't missing anything.

Disregard the first line - it doesn't include parity. In your case, 6x3TB = 6x2.7TiB = 16.2TiB. 11.3 + 4.9 = 16.2TiB.

The second line is your pool size with parity. So, your 6x3TB RAIDz1, gives you a theoretical maximum of ~ 5x2.7TiB -> 13.5TiB. There's some overhead and your system dataset takes up space too.

So, your numbers are fine.
