Thanks Poul! For reference to everyone finding this thread, this procedure works indeed as intended: ceph osd getcrushmap -o crush.map crushtool -d crush.map -o crush.txt # edit crush rule: "step take ServerRoom class hdd" --> "step take ServerRoom class ssd" crushtool -o crush-new.map -c crush.txt ceph osd set norebalance ceph osd set nobackfill ceph osd setcrushmap -i crush-new.map # wait for peering to finish, you will see 100% objects misplaced but all PGs active+... ceph osd unset norebalance ceph osd unset nobackfill Ceph will now happily move objects while storage is fully redundant and r/w accessible.
