I have added a large drive to my desktop for back up purposes. I am
using rsnapshot to backup just a couple of times a week. Since the
drive will be rarely accessed I added:
/dev/sdb {
spindown_time = 180
}
To hdparm.conf to spin down the disk after 15 minutes of inactivity
to save power (yea goin' green!)
Everything is working right except when I go to restart or shut down
the pc. When I do that, right before init runs halt the hard drive
spins up and then the pc shuts off. Does the hard drive have to
spin up in order to flush a buffer or something before shut down?
Any way to get around this? The sudden spin up and then shut off
doesn't seem like it would be good for the disk, makes alot of noise
when it does it too.
Is this just "normal" or what?
Yes. The drive must spin up before being dismounted.
I suggest that you only mount the drive when needed. Besides the
safety of preventing you from accidentally deleting needed files, it
boosts the likelihood that the kernel won't need to spin it up during
shutdown.
Hmm, sounded like a good idea but with the drive unmounted and spun
down, it still spins up right before a shut down or a reboot. :(
Hmmm, very puzzling. I'd ask lkml.
Anyway, does this *actually* hurt anything, or just make a moment of
noise and kinda make you a bit worried?
That is what I am wondering. Besides worrying, it also causes about a 5
second delay on shutdown while the kernel (or whatever) waits for it to
spin up, to then just shut it off.
