Please don't use an EC pool with 2+1, that configuration makes no sense. min_size 3 is the default for that pool, yes. That means your data will be unavailable if any OSD is offline. Reducing min_size to 2 means you are accepting writes when you cannot guarantee durability which will cause problems in the long run.
