I still had 64 PGs in all the default pools. Is that expected? Do I need to set up ceph.conf before running "new"? If I do it seems to overwrite my ceph.conf with the default ceph.conf. For pools created later, the pool create command requires you specify the number of PGs, so I can't really judge if the default PG value is working. Trying to run "ceph osd pool create {pool-name} {pg-num}" without supplying a value for pg-num fails. I was able to adjust the PGs in the default pools after they were created - that works as described. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
