Yeah, 100M reaches the current default settings of the blockgroups, we'd need some adjustments for such filesystems. > Can be fixed by checking raid support only based on "large disk count". We can try to make it work even in the weird device size combinations, but not at the cost of complicating the code unnecessarily. I don't want to discourage you, so if you eg. make it work with 64M devices that would be good enough though going even lower should be possible. > This fix maybe conflict with Chandan's work, so I'll begin work after > he finished.
