FreeNAS Accounting - How much storage? Where?

[voyager529]

Hello everyone,

I'm a bit confused regarding how much space is available, and where.

My NAS has two volumes, each a RAIDz2 of 3TBytes drives. 15 raw TBytes each, 9TBytes after the RAID...a little overhead for formatting and math, leaves me with approximately 8.5 TBytes per volume, give or take...right?

So, pool2's used + free = 7.81TB, and iocage used + free = 4.7TB, but I have 8.35TB free on a volume that's at best 9TB large but already has 3.12TB of data on it?
Meanwhile, nas's used + free = 7.82TB, but has 6.71TB free on a volume that too is 9TB tops but has 4.1TB used?

I'm not saying anything is wrong here, but clearly I'm reading these numbers incorrectly.

Thank you for the translation!!

Remember the difference between TB and TiB. Hard disks are measured in TB (10^12 bytes), while the GUI uses TiB (2^40 bytes). 1 TB ~= 0.9 TiB.
