Didn't I already reply to this??.. The kernel isn't being "smart". The code in 2.4 always does reconstruction (i.e. rebuilding a failed drive) one array at a time, simply because that is the way the code works. The code in 2.6 is more sensible and allows parallel reconstruction provided there is no sharing of devices. resync (after an unclean shutdown) happens in parallel (except where device sharing exists) in both 2.4 and 2.6 NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
