Off-topic, sorry, but if I understand you your layering is: disks - mdraid - lvm - bcache - filesystem? So you created an lv which is the backing device for bcache? I've been looking at using bcache, but I was planning on switching the ordering and putting bcache on top of the mdraid, then creating a pv for lvm on the bcache device: disks - mdraid - bcache - lvm - filesystem Out of curiosity, I was wondering why you layered the other way. Thanks. -- 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
