USB HDD standby - Can sdparm be added to the distro?

zarusz · February 4, 2018 at 11:54 AM

Hello,

First of all thank you for the work on LibreELEC.

I have few HDD attached via the USB interface to my Rock64. I would want to be able spin down all disks after some inactivity. Two disks spin down fine using the pre-installed hdparm. However, my 3rd disk (Segate) requires sdparm to spin it down (this disk has SCSI interface). As I understand for LibreELEC packages cannot be installed by the user.

Can the sdparm be added to the distribution as well with your next release?

Right now, my workaround is to run a docker debian container in privileged mode to be able to install sdparm and spin down the disk:

Code

sdparm --flexible -6 -l --save --set SCT=54000 /dev/sdb
sdparm --flexible -6 -l --save --set STANDBY=1 /dev/sdb

(54000 * 0.1s) = 1.5h

Docker:

Code

docker run --rm --privileged --device=/dev/sda:/dev/sda -it arm64v8/debian

apt-get update
apt-get install sdparm -y

Version:

Code

Linux Rock64 4.4.103 #1 SMP Fri Dec 22 08:22:26 CET 2017 aarch64 GNU/Linux

zarusz or anyone finding this through search engine. I bought a Seagate HDD which needs sdparm. With the above, I managed to optimise to one command:

Code

docker run --rm --privileged --device=/dev/sda:/dev/sda arm64v8/debian /bin/bash -xec 'apt-get update && apt-get install sdparm -y && sdparm --flexible -6 -l --save --set STANDBY=1 /dev/sda && sdparm --flexible -6 -v -S -p po --set=SCT=9000 /dev/sda'

I'd see if you can can simply copy the binary from the container to /storage and run from there. It's never guaranteed, but simple binaries without heavy runtime dependencies can often be copied over from e.g. Rasberry Pi OS to an LE install. If it works, use autostart.sh to add the binaries /storage/location to $PATH at boot time and you can avoid the complication of docker.

I wonder if hdparm could help here putting the drive into sleep mode

- I couldn't exactly get what you're also doing with drive, though -

I esp. mean the hdparm parameter "-K",

see:

hdparm(8) - Linux manual page

-K

"... retain the settings for -APSWXZ over a soft reset ..."

"soft reset" := reboot ?

-S

"Put the drive into idle (low-power) mode ..."

chewitt Thanks for the tip and response, I didn't realize/think of pulling binaries from raspberryOS... that's worth trying out. I actually run docker-compose as a bin as well... I'll post here if successful.. for now it's running - albeit a bit over engineered.

GDPR-7 Thanks for the suggestion. Unfortunately hdparm doesn't work on this type/brand of disk. (Western Digital)... wish I bought Seagate like I did before.

care to provide the exact disk/brand type ?

joop · May 30, 2022 at 6:42 PM

It's a Western Digital Elements Portable 5 TB - USB 3.0 - WDBU6Y0050BBK

me is confused, that your disk doesn't support hdparm.

from a newer WD disk (WD-Black-P10) made years later as yours.

I haven't tried to set power feature, though.

anyway my mom owns a 1 TB of your disk type and I'll check hdparm support next time I get my fingers on the disk (700 km away)

Can the sdparm be added to the distribution as well with your next release?

seems it is added:

zarusz / GDPR-7 been in the backlog for a while. Thought it was time I PRed a system-tools update 👍

joop · June 4, 2022 at 7:33 PM

WOW! That's really cool. Thanks to everyone advising! Happy to use it once it lands in stable. Keep up the good work, I'm grateful.

I believe @zarusz is the one to mark as resolved?
