Hi I have a 4 drive array with 1 TB Hitachi disks, formatted as raid10,f2 I had some strange observations: 1. while resyncing I could get the raid to give me about 320 MB/s in sequential read, which was good. After resync had been done, and with all 4 drives active, I only get 115 MB/s. 2. while resyncing, the IO rate on each disk is about 27 MB/s - and the rate of each sdisk is about 82 MB/s. Why is this? best regards keld -- 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
