Thread: Firmware to spin-down HDD?

  1. #61
    I would really like to spin down my HDD when it is inactive for 20 minutes. When I try
    PHP Code:
     /usr/local/sbin/scsi-stop /dev/scsi/host0/bus0/target0/lun
    0
    /disc 
    , I get this error:
    PHP Code:
    /dev/scsi/host0/bus0/target0/lun0/disc is not a SCSI block device 
    Am I doing something wrong, or does it just not work with my HDD. If it doesn't work, are there any other options?

    scsi-stop in RAID1

    I'm using two 1tb discs in RAID1 (using mdadm) and mounted as md0

    Code:
    $ cat /proc/mdstat
    Personalities : [linear] [raid0] [raid1] [raid5] [multipath]
    read_ahead 1024 sectors
    md0 : active raid1 scsi/host0/bus0/target0/lun0/part1[0] scsi/host1/bus0/target0/lun0/part1[1]
          976759936 blocks [2/2] [UU]
    if I use the scsi-stop script (one for each disc) the discs spindown correctly but when the discs are needed again only one disc resume, breaking the RAID sync. Is there a way to stop this from happen or another script to use raid md0?

    Code:
    scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc
    scsi-stop.sh /dev/scsi/host1/bus0/target0/lun0/disc
    the discs:

    Code:
    $ cat /proc/scsi/usb-storage-0/0

    Hi, I'm actually using teddy_bear's USB Tomato mod on a WL-520GU (stupid 4 MB flash...), and it includes scsi-stop and scsi-start, and I wanted to share my experience with getting it working.

    I used a watt-meter to verify that the disk actually did spin down or up. My setup involves an external enclosure with the following stats.

    Code:
       Host scsi0: usb-storage
           Vendor: JMicron
          Product: JM20336 SATA, USB Combo
    Serial Number: DA0150217888
         Protocol: Transparent SCSI
        Transport: Bulk
             GUID: 152d23360000da0150217888
         Attached: Yes
             Port: 1
              Bus: 00:03.1-1
    
    Vendor=152d ProdID=2336
    This is very similar to one that doesn't work (PID=2338). But I had to do something funny to get mine to work. If I call scsi-stop, the disk spins down, and when I go to access it, the disk becomes inaccessible. If I call scsi-stop and then scsi-start before accessing the disk, it behaves correctly, staying spun down until I go to access it.

    There are other Tomato-specific requirements for scsi-stop and scsi-start. You need to put the script in /jffs, and you need the build with awk. Here's the final script with the other Tomato-specific changes.

    Code:
    #!/bin/sh
    if /usr/bin/[ $# -ne 1 ]; then
            /bin/echo 1>&2 "Usage: $0 <device>"
            exit 1
    fi
    
    PERIOD=30
    BOUNDARY=1200
    SCSISTOP=scsi-stop
    SCSISTART=scsi-start
    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 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
                            $SCSISTART $1
                            time=`/bin/date '+%b %e %H:%M:%S'`
                            /bin/echo "$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

    Question Stoppin your hard drive motor on latest firmware.

    Hy , i have a question for you guys:

    How can i stop my HDD from spinning when i don't need it ?

    I read this post: http://wl500g.info/showthread.php?t=7836&page=5 and i tryied xander solution:

    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.
    but seems that my hdd doesn't work through scsi mode because i get:

    Code:
    /dev/scsi/host0/bus0/target0/lun0/disc: No such file or directory
    and when i try the path that i think is correct ( newbie, i know )

    Code:
    [admin@RouterASSUS work]$ scsi-stop /dev/discs/disca/disc
    i get:

    Code:
    /dev/discs/disca/disc is not a SCSI block device
    I have latest 1.9.2.7-rtn-r3497 firmware from http://wl500g.googlecode.com/, and installed by wengi tutorial from: http://wl500g.info/showthread.php?t=10307 (with disca changes of course)

    Can anybody help ? Thank you !

    Hi ,

    you can modify that script for you needs ,plase it somwhere and make a cron job:
    It looks ugly , but worked for me.

    #!/bin/bash
    DISKNAME=sdd
    now=`/opt/bin/date`
    a=0
    #check 70 times with 0.1s gaps,
    #and go on adding
    for i in `seq 0 70`
    do
    b=`awk '/$DISKNAME/ {print $12}' /proc/diskstats`
    a=`expr $a + $b`
    sleep 0.1s
    done
    echo $a
    if [ $a == 0 ]
    then
    echo "$now /dev/sdd No Activity-->>spindown" >> /opt/var/log/syslog.log
    /opt/bin/sync
    /opt/bin/sdparm --flexible --command=sync /dev/$DISKNAME &>/dev/null
    /opt/bin/sdparm --flexible --command=stop /dev/$DISKNAME &>/dev/null
    /opt/bin/sdparm --flexible --command=stop /dev/$DISKNAME &>/dev/null
    /opt/bin/sg_start --stop /dev/$DISKNAME
    /opt/bin/sg_start --stop /dev/$DISKNAME
    /opt/bin/sg_start 0 --pc=2 /dev/$DISKNAME
    /opt/bin/sg_start 0 --pc=2 /dev/$DISKNAME
    /opt/bin/sg_start 0 --pc=3 /dev/$DISKNAME
    /opt/bin/sg_start 0 --pc=3 /dev/$DISKNAME
    else
    echo "$now /dev/sdd Active-->wait ....." >> /opt/var/log/syslog.log
    fi
    exit 0


    Of cours you have to :
    ipkg install sg3-utils
    ipkg install sdparm

    Talking

    thanks a lot, but how can i test it before because doesn't work on all hhd's ?

    And btw what do i put in crontab ? what line, or can i put the script in init.d ?
    And second, disk name i have to put my disk name ? and the time for waiting to idle is editable ? thank you very much!

    PS: when i try a simple command

    [admin@RouterASSUS root]$ /opt/bin/sg_start --stop /dev/discs/disca

    i get

    Error trying to open /dev/discs/disca: Is a directory

    even when i enter:
    [admin@RouterASSUS root]$ /opt/bin/sg_start --stop /dev/$DISKNAME

    i get:

    Error trying to open /dev/: Is a directory

    I used the old scsi tools to do the same thing: http://wpte.kicks-ass.net/forum/showthread.php?tid=4
    it's a modification of the old d script

  14. #74
    hy, that is what i was looking for, but can i issue a command before all this to see if the hdd is stopping ? like in the old scsi-stop ?

    2. that is my problem i can't find hdd name .......

    well the harddrives are labeled like "sdx" with x as a or b or c etc.
    so your first drive is called "sda" your first partition on sda is called "sda1" etc.
    you can check it in /dev :
    ls /dev/ | grep sd
    for me it shows this:
    sda
    sda1
    sda2
    sda3
    sdb
    sdb1
    you can try if the script will work like this:
    /usr/sbin/scsi-stop /dev/sda
