Hello, at the moment I'm trying to find a bottleneck on my lamp-server with opensuse 11.4 (Kernel 2.6.37.6) Sometimes the system has a very poor performance because of a high io-wait. If I watch the systems disk-access with "atop -dD" I can see that sda is the most of the time at a load of 10%, sdb sometimes is at 100% or higher at the same time. In my opinion in a Raid1-System both disk should have nearly the same load. Or may I wrong whis this? Both harddisks where changed 3 Weeks ago, /proc/mdstat shows that the rebuild was successfull and the array is functional. Today I've changed th SATA-Cable and the Port on the Maindboard of sdb, but the behaviour is still the same. Both disks passed the extended smart-self-test. Any ideas about that?
