Fast write enabled would mean that the primary OSD sends #size copies to the

client as soon as min_size ACKs have been received from the peers (including
itself). In this way, one can tolerate (size-min_size) slow(er) OSDs (slow
for whatever reason) without suffering performance penalties immediately
(only after too many requests started piling up, which will show as a slow
requests warning).
What happens if there occurs an error on the slowest osd after the min_size ACK has already been send to the client?
This should not be different than what exists today..unless of-course if
the error happens on the local/primary osd
