Hi Budai, I agree with Nathan, just switch the crush rule. I've recently done this on one of our clusters. Create a new crush rule the same as your old one except with different failure domain. Then use: ceph osd pool set {pool_name} crush_rule {new_rule_name} Very easy. This may kick off some backfill so I'd suggest setting norebalance before doing this.
