Hello,

I can now already answer some of my questions, thought others not:

> In ext3 did each block group contain always 1 block? 
> If not, then how many?

This information is in ext4_super_block.s_blocks_per_group

> 2> I see that the number of groups inside a flexible group is

I am still very much interesting in knowing this! Are all groups flexible 
groups when FLEX_BG feature is activated?

I found this image for how things relate to one another without flex_bg:

Does anyone know if there is a simular image with flex_bg???

thanks,
