Ceph is not able to write to both journal and disks simultaneously? For example, by using SSD for operating system and journal, we will be able to have not least than 100GB of journal that is a large amount of data wrote at SSD speed. When ceph has to flush this data to disks, will stop to write more data to journal? -- 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
