Hi,

 

I was looking for a way to put my server into standby mode (S3) and make it resume at a specified time. In Linux this can be done with the rtcwake command. According to http://lime-technology.com/forum/index.php?topic=9517.0 unRAID might not include rtcwake. It turns out that the command is there (using unRAID 4.6) but it complains about a missing device when I try to use it:

 

root@NAS:~# rtcwake -s 60 -m mem
rtcwake: assuming RTC uses UTC ...
/sys/class/rtc/rtc0/device/power/wakeup: No such file or directory
rtcwake: /dev/rtc0 not enabled for wakeup events

 

What does this mean and how can I make this work?

 

Not a direct answer to your question, but maybe you can send a magic packet from another computer running in your network at a specified time and wake up unRaid?

I would like the unRAID server to wake up on it's own just before the mover script is started at 3:40 am. In this scenario all other computers are turned off.

Many BIOS have a feature to power up at a specific time.  check out that as a possibility.

 

Before experimenting, press "Stop" to cleanly stop your server.  That way, if you are forced to power cycle to get control back you'll not be faced with a lengthy parity check. 

 

To put the unRAID server to sleep, you can try:

echo 3 > /proc/acpi/sleep

 

If /proc/acpi/sleep does not put your server to sleep, then S3 mode is not enabled on your motherboard.

 

You can type:

cat /proc/acpi/sleep

to see what is enabled.

 

May people have discovered that their NIC needs to be reset after a S3 sleep to respond again, same with some video chipsets.

 

One utility to suspend better is "s2ram" and is attached here http://lime-technology.com/forum/index.php?topic=3657.msg70945#msg70945/index.php?topic=3657.msg70945#msg70945'>http://lime-technology.com/forum/index.php?topic=3657.msg70945#msg70945/index.php?topic=3657.msg70945#msg70945

(You use "s2ram -f -p" instead of  "echo 3 > /proc/acpi/sleep" to go to sleep)

 

It is described here: http://old-en.opensuse.org/S2ram

 

You can try many of the things listed in this thread: http://lime-technology.com/forum/index.php?topic=3657

 

Lastly, you can set the "mover" script to run at any time.  No need to run it at 3:40 AM.

Apparently my board does not support S3. I am going to let it rest for now. I am still wondering whether rtcwake would work or not if my board had S3.

Which mobo do you have exactly? Thanks.

My board doesn't support s3 sleep either. The best you can do is

echo -n shallow > /sys/power/mem_sleep
# Then do
echo -n mem > /sys/power/state

Probably too late though.
