Hello, I have a question regarding the RAID1 performance. I tought the RAID1 will access disk in a con-current way, but today I installed a 2.4-18 (Redhat 9.0). Seems RAID1 code is not doing the disk access in a balanced way? I see single disk is faster the RAID1. First, do dd, read from /dev/zero write to disk, then dd again, read from disk write write to /dev/null, in both cases, single disk out run 2 disk RAID1. Any one can help me to understand this? Thank you so much. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
