Hi! Currently I have a cluster with four hosts and 4x HDDs + 4 SSDs per host. I also have replication rules to distinguish between HDD and SSD (and failure-domain set to rack) which are mapped to pools.
What happens if I add a heterogeneous host with 1x SSD and 1x NVMe (where NVMe will be a new device-class based rule)? Will the crush weight be calculated from the OSDs up to the failure-domain based on the crush rule? The only crush-weights I know and see are those shown by "ceph osd tree". Kind regards Kevin
