If you set min_size to 2 or more, it will disable reads and writes to the pool by blocking requests. Min_size is the minimum copies of a PG that need to be online to allow it to the data. If you only have 1 copy, then it will prevent io. It's not a flag you can set on the pool, but it should work out. If you have size=3, then min_size=3 should block most io until the pool is almost fully backfilled.
