Hi, > I hope not. How could I tell? It's not something I've explicitly enabled. It's disabled by default. So you'd have to have enabled it either in ceph.conf or directly in the device path in the xen config. (option is 'rbd cache', http://ceph.com/docs/next/rbd/rbd-config-ref/ ) Cheers, Sylvain -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
