    unRAID Vendor Forum?

    in Forum Feedback

    Posted

    As someone who has spent most of his working life in the high-end IT market, a vendor tends to be someone who just sells boxes with no or little add-on. A reseller tends to have consultancy and/or support bolted on and offer a more bespoke service than the vendors (AKA box-shifters). The people who build their own hardware with another company's software on top are called OEMs (although OEM is more of a PC term and doesn't really appear much in the high-end IT market).

    how to boot from cold boot and start the array automatically

    You've got two options - you could put your server into S3 sleep but leave it powered on 24/7, then just wake it up from another workstation with the Wake-On LAN magic packet.

     

    Alternatively, you could use a cron job to shut your server down at a certain time and use a timer on the power socket to turn the power off a few minutes later then back on again in the morning. You'll need to change the power loss settings in the BIOS to "Always on" or similar.

     

    Just bear in mind that the second method isn't really possible at the moment, because there's no safe way to shut down the server from the command line at the moment (AFAIK)

    Next Stable

    As stated elsewhere on the forums, Tom is working on updating the Wiki documentation. Once that is done, he'll release 5.0-stable into the wild.

     

    Yes, it's taking a bit of time, but wouldn't you rather have a stable release together with complete and up-to-date documentation?

    It's a matter of style and is just an example.

    I was thinking more along the lines that in your original example, emhttp would be run in safe mode but not in normal mode? Shouldn't it be:

    # Load emhttp before anything else - we always need that running ;-)
/usr/local/sbin/emhttp &

# If "unraidsafemode" present on kernel command line, skip all add-ons
if grep -wq unraidsafemode /proc/cmdline ; then
  logger "unRAID Safe Mode (unraidsafemode) has been set"

  #Do your critical safe mode code here. then exit.
  #e.g.
  #/boot/unmenu/uu
  exit
else
  #Other code if not in safe mode. 
fi

    The easiest way is to add the sleep command to your crontab file.

    Add the following lines your go script:

    # Set a daily sleep in root's crontab:

# Append new entries to root's crontab:
cat <<-EOF >> /tmp/crontab.root

# Send server to sleep at 23:15 every day
15 23 * * * echo -n mem > /sys/power/state

EOF

# Update root's crontab:
cp /tmp/crontab.root /var/spool/cron/crontabs/root-
crontab /tmp/crontab.root -u root

     

    You may want to do a few other things, such as check for network or activity, run the mover before sleeping, etc. You'd need to put these things in a script and call the script from cron instead. Take a look here for further information - although read through to the end of the thread, as there are a few changes that need to be made to the posted script.

     

    I don't know how you'd go about waking the server up at a specified time - I think you'd have to get another machine to send a WOL command at 6am?

    It doesn't necessarily have to be the motherboard - it could be that the PSU has died, or at least died enough that  it can't power everything in the system (I've had that happen a few times before. Found out the expensive way first time round, learnt my lesson next time it happened ;) )

    Are you wanting your unRAID server to wake up other machines or be woken up by other machines.

     

    If it's the latter, there are scripts available on this site and in the Wiki to put your unRAID server to sleep when there's no activity. Check here for more info.

     

    If it's the former, there are scripts available that will wake up other machines. Here's a Python one I use on my main server (to wake my unRAID server up before starting a backup). I can't remember where I got it from.
