Thread: Firmware to spin-down HDD?

  1. #1

    Firmware to spin-down HDD?

    After days of messing, i've finally got my WL-500gP doing pretty much what I want. However, the one remaining annoyance is that the USB hard drive won't spin down, and to remove it I need to login to the web interface just to say "eject"... which isn't particularly helpful.

    So, i'm looking for a new firmware with that implemented. I'm currently using the standard Asus FW and happy enough with that - i need to keep the ability for it to operate as a router (share the WAN connection with several wifi devices), to share a printer, to share a hard drive, and for a wired network device to be on the network too. Other than that, i'll happily lose all the other features.

    Are there any firmwares out there that can do that, and that are suitable for a linux-novice (i've played a teeny bit with Linux, and can get a friend to explain bits of it over the phone, but not experienced myself).

    I have read around this and other forums about the problem, and it does seem to be possible, but I can't do anything with the standard firmware, and the most common Oleg one doesn't seem to include sharing the USB drive. Also, I only have a laptop so can't directly connect the drive to an IDE interface to change the HDPARAM settings.

    Any suggestions very gratefully received!

    Here's the possible solution:
    1. Download http://oleg.wl500g.info/bin/scsi-stop - this binary is able to spin-down your disk immediately after execution.
    2. Place it somewhere on your router (you should be able to reach it via PATH environment variable) and make it executable.
    3. You can use the script I've written which works in background and spins down disk after some period of inactivity:
    http://wl500g.info/showpost.php?p=47135&postcount=10
    I use it this way (I named the script scsi-stop.sh):
    Code:
    ./scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc &
    It automatically writes some log messages to scsi-stop.log.
    It works for me. You can change it as you wish.

    Thanks a lot for that.

    Is it possible to do that on the standard firmware, or will I need Oleg's (or similar) to do it? I'm a little apprehensive to put the Oleg firmware on as the documentation suggests it doesn't support the USB hard drives.

    I noticed I couldn't telnet into the box with the standard firmware, how would I go about putting that file on it, and your script?

    Cheers

    Well, this is definitely untrue.

    I don't know whether my solution can work with standard firmware. I really don't think so. I recommend you to replace it.
    I didn't said that the most appropriate place for scsi-stop and scsi-stop.sh is in the router's flash so you should place it somewhere in /usr/local and then do:
    Code:
    flashfs save
    flashfs commit
    flashfs enable
    I don't think that this feature is implemented in the Asus firmware.

    I am impressed that someone finally managed to find a way to spin down HDDs. I understand that Oleg was the hero (again).
    Because I did not know of this solution at the time, I have bought an Western Digital MyBook Essential 250GB. This drive spins down by itself.

    hi Xander,

    great that you managed it!!!

    I'm using your script and it works really nice.

    Can you write a complete HOW-TO for the beginners?
    WL-500gP => 1.9.2.7-7g (2007-04-06)

    Well, Ok, I'll write it soon. I must tell everybody that this binary is not working with several hard drives. This was reported in the similar topic in the Russian forum.
    Oleg said also that this tool is a part of scsi-idle package, so you can compile it yourself. Just grab sources here: http://lost-habit.com/scsi.html

    Hi,
    is possible to use this for wl-500gx too?
    But I will wait for tutorial to beginners

    HI Xander
    something new about the tutorial of spining-down disc?
    Can you write here which kind of disc isn't suported?(My knowledges of Russia language are nothing )

    THX very much

    Tutorial.

    If you want to spindown your external HDD, scsi-stop tool may help you. This tool is a part of scsi-idle package. If you don't want to build the tool from sources, just use the first link to get a prebuilt binary provided by Oleg.

    Since you want to spindown your disk it is not very sensible to place the binary on it. So the appropriate place is the router's flash.

    Steps:
    1.
    Code:
    cd /usr/local/sbin
    wget http://oleg.wl500g.info/bin/scsi-stop
    chmod a+x scsi-stop
    2. Now you can test your disk for compatibility. Please, ensure your login shell is /bin/sh and you run scsi-stop in it. cat /etc/passwd will help you to find out.
    Code:
    /usr/local/sbin/scsi-stop /dev/scsi/host0/bus0/target0/lun0/disc
    If your disk continues to spin then scsi-stop most likely doesn't support your ide->usb (or sata->usb) box.
    Please, post your results and your hardware here. Let other people know whether it is supported or not. And please add the output of
    Code:
    cat /proc/scsi/usb-storage-0/0
    and search for corresponding VendorID&ProductID in the output of
    Code:
    cat /proc/bus/usb/devices
    3. If you were successful you maybe would want to use my script for automatic spindown:
    Code:
    #!/bin/sh
    if /usr/bin/[ $# -ne 1 ]; then
            /bin/echo 1>&2 "Usage: $0 <device>"
            exit 1
    fi
    
    PERIOD=30
    BOUNDARY=1200
    SCSISTOP=/usr/local/sbin/scsi-stop
    LOGFILE=/tmp/scsi-stop.log
    
    searchstr="disk_io:"
    devaddr="(`/bin/ls -l $1 | /usr/bin/awk '{print($5 int($6/16))}'`)"
    
    str=`/bin/grep "$searchstr" /proc/stat | devaddr="$devaddr" /usr/bin/awk -v 'RS= |\n' -F : '{ if($1==ENVIRON["devaddr"]) print($2) }'`
    cooltime=0
    stopped=0
    
    while /bin/true; do
            /bin/sleep $PERIOD
            newstr=`/bin/grep "$searchstr" /proc/stat | devaddr="$devaddr" /usr/bin/awk -v 'RS= |\n' -F : '{ if($1==ENVIRON["devaddr"]) print($2) }'`
            if /usr/bin/[ "$newstr" = "$str" ]; then
                    cooltime=$(($cooltime + $PERIOD))
                    if /usr/bin/[ $cooltime -ge $BOUNDARY -a $stopped -eq 0 ]; then
                            $SCSISTOP $1
                            time=`/bin/date '+%b %e %H:%M:%S'`
                            /bin/echo "$time: Cooled down..." >> $LOGFILE
                            stopped=1
                    fi
            else
                    if /usr/bin/[ $cooltime -ne 0 ]; then
                            time=`/bin/date '+%b %e %H:%M:%S'`
                            /bin/echo "$time: Disk first used after $cooltime seconds" >> $LOGFILE
                    fi
                    cooltime=0
                    str=$newstr
                    stopped=0
            fi
    done
    You can change "period" and "boundary" variables. They are in seconds. With the current settings script will wake up every 30 seconds to gather information and after 20 minutes of inactivity it will stop disk.
    Do:
    Code:
    cd /usr/local/sbin
    cat > scsi-stop.sh
    <copy and paste the script>
    <press Ctrl-C>
    chmod a+x scsi-stop.sh
    To run script in background do, for example:
    Code:
    ./scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc &
    Notice that the script writes some log messages to /tmp/scsi-stop.log .

    4. Don't forget to do
    Code:
    flashfs save
    flashfs commit
    flashfs enable
    to save all the things in the router's flash.

    Hi All,

    Xander, thanks for the great tutorial! Worked perfectly. My results:

    I was actually surprised that such a cheap/generic HDD box would support HDD idling!

    Thanks,
