which process & file taking up disk IO?
...%util
1.28 65.38 5.10 9.97
Is it normal for the %util to be 9.97% for the above reads/ writes on a U320
drive? or perhaps i have a badly misconfigured server? the drive is 2 x 146GB,
RAID 1 using the LSI logic LSI22320-R card.
#elvtune /dev/sda
/dev/sda elevator ID 1
read_latency: 2048
write_latency: 8192
max_bomb_segments: 6
#cat /proc/sys/vm/bdflush
80 50 0 0 600 10000 80 70 0
Server is running CentOS 3.5; CPU and RAM are very much under utilised.
