Hi,
I used for a long time a RAIDZ1 pool with 9 disks ( 6 TB ) and got about 42 TB space.
Now I created a new RAIDZ2 pool with 12 disks ( again 6 TB ) and again I got about the same space as before..
What I don't really understand is how this works? I know there are some calculators out there but even then the disk space should be more I thought.
Even with the metadata and parity how come 10 disk space is reduced to 8 disk space?
