I think 'chassis' is OK. If you change host to chassis, you should have chassis declaration in the crushmap, as osds and hosts do. Using command for example, "ceph osd crush add-bucket chassis-1 chassis" and "ceph osd crush move host-1 chassis=chassis-1" should be executed. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
