Hi Ilya and all, Thanks for explaining. I'm confused about what "building" a crushmap means. After running #ceph osd crush tunables hammer data migrated around the cluster, so something changed. I was expecting that 'straw' would be replaced by 'straw2'. (Unfortunately I did not dump the crushmap prior to setting tunables to hammer, so I don't know what change did occur.) So I guess setting tunables to hammer is not "building" a crushmap. Could you give examples? Would creating a new pool on the cluster now use straw2? Thanks!
