Looking at the documentation here: http://ceph.newdream.net/wiki/Cluster_configuration you define a btrfs device as: btrfs devs = /dev/sdx Is there any way to change the device to use UUID instead since sdx can change between boots or when you replace hard drives. -- 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
