What are the ramifications to changing the recordsize of a zfs filesystem that
already has data on it?
I want to tune down the recordsize to speed up very small reads to a size that
is more in line with the read size. can I do this on a filestystem that has
data already on it and how does it

Hi Everyone,
Is it possible to use send/recv to change the recordsize, or does each
file need to be individually recreated/copied within a given dataset?
