GitHub user benjumanji edited a discussion: region aware ensemble placement (e=3,w=3,a=2) can't create new ledgers.
I have the following config (shortened for brevity) on pulsar 4.0.1 ``` bookkeeperClientRegionawarePolicyEnabled=true reppRegionsToWrite=euw1-az3;euw1-az1;euw1-az2 reppMinimumRegionsForDurability=2 ``` I have at least three bookies. If I try the aforementioned policy (e3,w3,a2) then the exception here: https://github.com/apache/bookkeeper/blob/0748423e3228f7cf61d2e1f2ab11e354ed84c0df/bookkeeper-server/src/main/java/org/apache/bookkeeper/client/RegionAwareEnsemblePlacementPolicy.java#L317 is thrown. <img width="1210" alt="Screenshot 2025-01-30 at 21 01 17" src="https://github.com/user-attachments/assets/001a603c-32ce-4d1f-aba9-fea20dd17032"; /> This makes little sense to me as `2 <= 3 - 3/2` evaluates to true. I am tempted to open an issue to suggest that the parameters used in the expression are logged in the exception, but that doesn't help me today :) Looking at the class instantiating the placement policy https://github.com/apache/pulsar/blob/12b057999f5674ae6da6b04ff8bd212d1904cc88/pulsar-broker/src/main/java/org/apache/pulsar/broker/BookKeeperClientFactoryImpl.java#L179 I can't see any obvious mistakes on my part.
