I've always used noflushd to spin down the drives I don't use much. Some of my older drives are really noise, and there's enough heat in there as it is. I just switched to a new system and I find on my new motherboard with a ICH5 SATA controller the system doesn't behave properly when the drives are spun down.
The entire system freezes periodically for anywhere from half a second to 10s. This happens about once a minute or so, sometimes more. During this time the entire system is frozen, but when it recovers it processes all the lost i/o.
I also find when there is i/o that should cause a drive to wake up it takes waay too long to wake up. It's as if the drive isn't even being woken up for 10-15s. Then I get dma timeouts in my logs.
Is it that the ICH5 controller is buggy and behaves poorly when drives are powered off? Or is it the driver that isn't handling something properly? Does anyone else use noflushd with the ICH5 driver?
