I did some more testing and apparently the issue can be avoided by choosing the deadline scheduler instead of cfq. Either configure the kernel with CONFIG_DEFAULT_IOSCHED="deadline" or select the deadline I/O scheduler per device. In my case: echo deadline >/sys/block/sda/queue/scheduler echo deadline >/sys/block/sdb/queue/scheduler -- Frank -- 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
