[ceph-users] Changing the crush rule of an existing pool

Hello Cephers, I just want to get confirmation on two things. I'm going to change the crush rule of an existing pool so that it uses SSDs instead of HDDs. 1. Will changing the rule cause any problems with the current workload? 2. Does Ceph manage the migration of data currently in use when the existing pool's rule is changed? If so, does it also delete the data on the old disks after the migration? Thanks in advance. BR, Huseyin Cotuk hcotuk@gmail.com
