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? I am using Ceph 0.94.2
