Hello, The following strikes me. I am new to Unraid, and have built a new setup. To start I took 3 pieces of WD 4TB drives. 1 used parity 2 as disk Total size for use is 8tb now. But after these two drives are added and formatted, Unraid shows that 76.6GB is already in use on both, with a total of 153 GB This leaves 7.84 GB free space. Is this normal or have I made a mistake in the setup?
