I came across two older dell md1220 shelves with 1tb drives in it. I originally only had one shelf installed, and I hooked everything up and it was great.

zpool list
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
freenas-boot 408G 1.52G 406G - - 0% 1.00x ONLINE -
tank1 43.5T 21.0T 22.5T - 18% 48% 1.00x ONLINE /mnt

I see where it says 43T, and there's 22.5T left, but from an OS perspective it doesn't show that.

freenas.int:/mnt/tank1/md1
23T 7.8T 15T 36% /opt/md1
freenas.int:/mnt/tank1/md2
21T 6.4T 15T 31% /opt/md2

15T is a ton of space, and I'll be good for a long time, but the numbers don't add up. Can someone shed some light on this?

Just read this post again, and figured I would clarify. Since they are both on tank1, and the md1/md2 weren't created with a size specifier, why would they show different size of the disk. (23T and 21T) I would assume they would both be the same.

The free space for the pool is the total available space. The primary dataset is the space available after parity.
