Openelec addon, power saving, hdd sleep

[Schnoogemetzger]

The power saving settings for hdd sleep doesn't work as expected. At least for connected USB drives. If the power saving is enabled, the "sleep hard drive after" value isn't recognized. So, nothing happens (no sleep).

Up to version 3.0.6 only hdparm was used and this tool doesn't support usb drives. In 3.0.6 I compiled hd-idle from source, stored it under /storage and configured it in autostart.sh. Worked. Since 3.2 hd-idle is implemented and it should be able to set a usb drive into sleep, after I activated hdd standby in settings addon. As I wrote, nothing happens and I can't see a hd-idle process.

Additional info: If I start hd-idle via autostart.sh and hdd sleep isn't enabled in the power saving section, the hd-idle process will be terminated.

For more detailed information, please have a look at my forum post [1].

hd-idle with settings addon is not intended to work with the drive you BOOT from. if you try that - this is not a bug. if you want hd-idle working for bootdrive - you can still copy the binary to /storage, rename it and use autostart.sh.

Sorry, I forgot that one: I use a raspberry Pi, so I boot from a SD Card. The USB drive is for my data.

enable debugging in xbmc. reboot. wait 2 min. post xbmc debug log. EDIT: is /dev/sdaX mounted as /storage ?

Nope, the flashcard is mounted as /storage:

xbmc.log debug (loglevel 1): http://pastebin.com/T1WHY9yU

For the avoidance of doubt: HDD Power saving is on.

[stefansaraev]

this is not a debug log, unfortunately :)

EDIT: ok. add "debugging" to kernel parameters in cmdline.txt

EDIT: and please keep autostart.sh clean while testing.

[Schnoogemetzger]

this is not a debug log, unfortunately :)

Oh, sorry, I thought you only need xbmc.log with debug level. autostart.sh is empty.

I add debugging to the cmdline:

OpenELEC:~ # cat /flash/cmdline.txt 
boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 ssh debugging

To play safe, what log file do you need? log/messages? Or is there a new file, if debugging is on and I overlooked it?

[stefansaraev]

I need /storage/.xbmc/temp/xbmc.log. with "debugging" in cmdline.txt and debug enabled in xbmc -> settings -> system -> debugging. (might work without debug in xbmc but better enable it, just in case)

[Schnoogemetzger]

Ok, I deliver it tomorrow. Thx so far.

[stefansaraev]

thanks for reporting. no need to send logs. I could reproduce it here. fix coming in next release

[jchannon]

I still have this issue. I'm running XBMC 12.2 and OpenElec 3.2.4

My xbmc log with debugging turned on is at https://gist.github.com/jchannon/70b8a6d6ce618a48505f

I mount it my external hdd with this in the autostart.sh file

 #!/bin/sh
 (sleep 30; \
 mkdir /media/ExternalHDD; \
 mount /dev/sda2 /media/ExternalHDD \
 )&

[stefansaraev]

this is normal, as your hdd is mounted AFTER hd-idle is started. you dont have to mount it manualy - openelec will automount it on boot up.
