If you take two physical disks, use mdraid, and then create a single pv on top, every lv is redundant. If you take two physical disks, make two separate pv's, you can either have a non-redundant lv, or use lvm raid and have a redundant lv, and you can mix and match as you wish. This is based on my understanding of lvm raid, which is not guaranteed correct ;), and as such should be taken as an opinion only :). -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
