Michael; I run a Nautilus cluster, but all I had to do was change the rule associated with the pool, and ceph moved the data. Thank you, Dominic L.

As soon as I started the radosgw service, I notice that it created a handful of new pools. These pools were assigned the 'replicated_data' crush rule automatically. I have a mixed hdd/ssd/nvme cluster, and this 'replicated_data' crush rule spans all device types. I would like radosgw to use a replicated SSD pool and avoid the HDDs. What is the recommended way to change the crush device class for these pools without risking the loss of any data in the pools? I will note that I have not yet written any user data to the pools. Everything in them was added by the radosgw process automatically. --Mike _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
