Hello, I have a running cluster, which use the (previous) default CRUSH rule, with : step take default step choose firstn 0 type osd step emit Since I have multiple OSD in the same host, I need to change that to have better redondancy. My crush map use types datacenter → room → network → rack → host → osd. For now I would like to replicate per "network", I suppose I can simply replace "step choose firstn 0 type osd" per "step choose firstn 0 type network" ; but is it safe to do that on a running cluster ? And I suppose it will throw a lot of data move, is it possible to do that «slowly», to avoid production slowdown ? Thanks, Olivier B. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
