[ceph-users] Re: Change crush rule on pool

I would like to change the crush rule so data lands on ssd instead of hdd, can this be done on the fly and migration will just happen or do I need to do something to move data?

I would actually like to relocate my object store to a new storage tier. Is the best to: 1) create new pool on storage tier (SSD) 2) stop activity 3) rados cppool data to the new one. 4) rename the pool back into the "default.rgw.buckets.data" pool. Done? Thanks.
