1/3 of your raw data on the osds will be deleted and then it move a bunch
around. I haven't done it personally, but I would guess somewhere in the range
of 50-70% data movement. It will depend on how many pgs you have, failure
domains (hosts by default), etc.

movement will happen when I reduce the size from 3 to 2? The min_size is
already at 1.

Make sure to also adjust your min_size. Having those be the same number can
cause issues if and when you lose an osd from your cluster.
Like Wido said, you can change the size of a replica pool at any time, it will
just cause a lot of data to move.
