[smartmontools-support] Sleeping drives don't wake.

[Jon H. <jd_...@ya...>]

Hello,

i have 4 Sata 500GB Seagates (i think) arranged as a raid 5 device which is them lvm'd.

They are all configured to spin down after 30mins of in activity.

Problem is they are all also configured to run a short test 5 times a week and a long test 2 days aweek.

The problem I have is if the drives are sleeping the test doesn't suitably wake them up. It tries to but the drives seem to take just slightly too long to spin up again and presumably when smartd tries again they haven't quite finished spinning up and it reports they are not smart capable.

I know it can work as i have engineered cases where they are not sleeping and the test commences find.

Also if i do a smartctl -a on a sleeping drive it pauses and after a second or 2 reports the drive isn't smart capable - I can audibly hear the drive still spinning up. Once complete if i run again it completes fine.

Any help? I'd like to know these precious beauties are being watched over!
