Disk re-starts after spin-down

neok · 2009-03-12 14:39:45

Hi,

After a recent -Syu, my unused spare disk re-starts after it is stopped in /etc/rc.local by /usr/bin/sdparm -C stop /dev/sda. The upgrade included udev, initscripts, klibc-udev and yslog-ng. If I do /usr/bin/sdparm -C stop /dev/sda again in a terminal, the disk stops and starts again, running unnecessarily.

Any ideas please?

My thanks in advance.

Are there any mounted partitions there or any program that might be trying to access the partitions there? Maybe you should use hdparm instead of sdparm. Maybe the -Y option will do what you want but read the man page before trying anything

I'm experiencing a situation very similar (or maybe identical) to yours. I wasn't able to find a solution so I just use `hdparm -S' in /etc/rc.local and have the disk spin down automatically after 10 minutes.

I have the same issue. "hdparm -y /dev/sda" or "hdparm -y /dev/hda" wont send my drives (sda and hda) to sleep.
I can hear it parking the head and starting to spin down but it immediately spins up again.

How can I find out what is waking up my drives?
"lsof | grep /dev/sda" shows nothing.

OK, I tried using hdparm -Y but I still have the same problem, in fact the disk starts even sooner, right after it starts spin-down! (with sdparm it starts after it completely stops spinning). I have tried hdparm -S 1 but there was no effect. I don't know if it will spin-down after a longer delay than the 5 sec specified though.

I hope this topic is also related to this http://bbs.archlinux.org/viewtopic.php? … 23#p503323. This may help you and solved in my case.

As asked above, is anything on the disk mounted? I find my disks spin up again if there's a partition mounted on them.

Ah, I forgot to reply to that - no, there is no mounted partitions on that disk or any reference to its partitions in /etc/fstab. Whatever it is, it started with the update I did a few days ago.
