Hi,
Ok, but I still don't get what advantage would I get from blocked IOs.
If I set size=2 and min_size=2 and during rebuild another disk dies on
the other node, I will loose data. I know that I should set size=3, it
is the much safer. But I don't see what is the advantage of blocked io ?

Hi,
As far as I understand if I set pool size 2, there is a chance to loose
data when another osd dies while there is rebuild ongoing. However, it
has to occur on the different host, because my crushmap forbids to store
replicas on the same physical node. I am not sure what would change if I
