I used 4/5/6/7/8 HDDs(All 12 TB, WD Red) to create a Raidz2 Storage Pool.
I found out that :
When creating a Raidz2 Storage Pool with six 12TB HDDs, the difference between "Estimated raw capacity" and "Available Space" is 3.55%.
However, when creating a Raidz2 Storage Pool with seven 12TB HDDs, the difference between "Estimated raw capacity" and "Available Space" is 9.82%.
Why the difference "Estimated raw capacity" and "Available Space" is not the same when using the different numbers of 12TB to create a Raidz2 Storage Pool?
