Yes but I already have some sort of test cluster with data in it. I don’t think there are commands to modify existing rules that are being used by pools.

This is safe to apply on production clusters, on EC pools too. k _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
