First picture,
App 27 used out of 403 avail. bunker 10Tib used out of 4Tib avail…
tank 5.63 Tib used out of 26 Tib avail
bunker is clearly not possible.
Second topology picture, 10.9Tib listed in topology, Usage shows correct at 32Tib. … oh hold on, those 10.9Tib is the size it’s saying is potentially available per drive…
The day that I become the tyrant of the planet, I will enforce: total/used/available, in that order. Also, dates will be YYYY/MM/DD HH:MM:SS everywhere.
So when 1984 comes along, remember to vote “@argumentum for tyrant of the planet”
TiB is 2^40 bytes whereas TB is 10^12 bytes which is about 10% less - so a 12TB drive is c, 12,000,000,000,000 bytes, which is c. 10.91TiB and this is what is shown in TrueNAS, and 3x this is 32.73TiB, less overheads leaving 32.16TiB useable.
Your tank pool is 32.16TiB, and you have 5.63TiB used and 26.53 free which total 32.16TiB exactly. QED
