The "osd crush update on start" config option is only ever used when the OSDs boot; you'll need to update it on the ceph.conf for every OSD. There's no need to do anything like rebooting though because the live value doesn't matter. And as a note, the "unchangeable" warning on config is unfortunately not entirely reliable. The reasons are somewhat baroque, but if you see it that doesn't always mean the command is ineffective. :/ -Greg > > Thanks > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
