Hi:
I just tried to install rhel 7.3 on a 4 disk raid6. it's a
minimal install but took 3 hours to finish. I found the disk
initialize speed is around 150MB/sec. in past the disk initialize
speed will down to slow speed when there are other disk IO, but it
seems not the case in rhel 7.3.
I have check the below parameter:
cat /proc/sys/dev/raid/speed_limit_min -> 1000
cat /proc/sys/dev/raid/speed_limit_max -> 200000
when the system is idle, the init speed is also about 150M/sec, so
the system is use all the power to init when there are other disk IO.
is it normal? where should I check?
thanks a lot for help!!
Regards,
tbskyd
