Hello, I have a test cluster of 12 OSDs, I deleted all pools then I set six of them out. After I created a Pool of 100 PG, I have the PGs stuck in creating or degraded state. Can you please advise. Does the Crush algo still
taking the OSDs marked as down in consideration? Even if I have data shouldn’t the cluster rebalance by itself?
