I am trying to figure out how to get FreeNAS 8 to sleep when inactive and, ideally, wake on lan activity (or, less ideally, wake on a WOL magic packet). However, as I've tried to search for information on how to do this, almost all discussions seem to be centered on FreeNAS 7. Also, the tools included in FreeBSD to do this seem to be missing (i.e. acpiconf, etc.).

Is there a way to get FreeNAS 8 to sleep and wake so that I don't have to leave the server running all the time? Given its usage level, it seems a waste to have the server running constantly.

There is no way to get FreeNAS to do a suspend, because AFAIK they didn't compile the necessary ACPI stuff into the system.

Actually I think I've been wrong here! I just found acpi feature request and trac commit log.

It sounds a little vague though, so you may want to ask at FreeNAS Dev Mailing list

  • Is there a reasonably easy way to build a custom FreeNAS build with ACPI on? If so, what OS would be needed to host the build? Would OS X work? I am guessing it would have a better shot than Linux... Jan 22, 2012 at 18:57
  • I wrote an edit. might have been wrong after all.

    Let us here know when you find an answer, since information on this is sparse and contradicting. Remember, it may help others, too if there is a definite answer here.

You can shut your freenas down by executing a plink.exe command. (Google "plink" to find the download area.)

If you can enable ssh access to your freenas, you can execute plink -ssh -pw [PASSWORD] [root]@[IP OF FREENAS] shutdown -p now where PASSWORD is the password of the freenas root user and IP OF FREENAS is the IP address of your freenas.

To wake up freenas, you can use a tool called wol.exe. If you use wol.exe followed by the mac-address of your network card it sends a wake-on-Lan package. (Google for "wol.exe".)

Both commands can be scripted and scheduled by the windows task scheduler.
