RAIDZ space efficiency #475

Closed jameskimmel closed 9 months ago

jameskimmel commented 9 months ago

I am pretty new to RAIDZ1 and maybe I am way off here.

I think it is not a padding block, but a parity block.

I also think that there is a an error in the raidz1 calculations. we will have 128K/2 = 64 stripes with 8K of data and 4K of parity each 64 stripes with 8k + 4k each would be 768k total. I tried to correct this and also make hopefully easier to understand for beginners like me.
