Yeah, those issues do get discussed at times on the Linux RAID list.
I've asked questions about it and been told that Linux software RAID
depends totally on what the driver tells it and nothing seems to be
don (as best I can tell) based on any fixed time. That's more of a
hardware controller issue. I was told that if the drive by itself
doesn't fail at the system level when it's spinning up, then it won't
fail at the RAID level either. However what it does if it has a
hardware error is a bit beyond me at this point. My intention is to
try and get better with smartd so that the drive is continually
monitored and see if I can get ahead of a failure with that.
