We recommend defining a reasonable number of placement groups and maintaining that number until Ceph’s placement group splitting and merging functionality matures." but they do not tell you how to increase that number (whether it's experimental or not) after a pool has been created. Also, they say the default number of PGs is 8, but "When you create a pool, set the number of placement groups to a reasonable value (e.g., 100)." If so, perhaps a different default should be used! -- Alex Bligh _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
