Re: Is there any way to delay reconstruction

[Mike Hardy <mhardy@h3c.com>]

I've had this problem. I turned the raid speed limit max to 0, slept for
a second (just because), did my hdparm commands, slept another second
(again, just because - may not be necessary), then turned the raid speed
limit back to something that was good for background reconstruction.

That got rid of my dropped interrupts
