It is time sensitive. You currently need to have (reasonably well) synchronized clocks. At the very minimum, the ceph-mon daemons need to run on machines with good time. There are also some oddities that can occur if the fs client doesn't match the metadata server... At some point we'll take a closer look at what we can do to make that less of a problem, but for now things will be a bit wonky. > Any plans to include exports/quotas in ceph file system ? > it will be a beauty if we have above to options, so that the space > in ceph cluster can be effectively allocated to client system. I'm not sure what you mean by exports, but quotas will be added eventually. Again, it's a ways out. sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
