• [專案]
  • 狀況：由於作業系統是在硬體 RAID 啟動狀態下安裝的，因此每當重開，系統又會回歸到原始狀態，故需要重新安裝。
  • 安裝 pre-built lustre package - ​http://www.pdsi-scidac.org/repository/debian/

    bio:~# echo "deb http://www.pdsi-scidac.org/repository/debian testing main" > /etc/apt/sources.list.d/lustre.list
    bio:~# apt-get update
    bio:~# apt-get install pdsi-scidac-keyring
    bio:~# apt-get install linux-image-2.6.22.19-lustre-686 lustre-modules-2.6.22.19-lustre-686 lustre-utils 
    

  • 安裝 firmware-bnx2

    bio:~# apt-get install firmware-bnx2
    

  • 解析 firmware-bnx2 安裝前與安裝後的 initrd.img 差異

    bio:~$ mkdir -p temp temp2
    bio:~$ cd temp
    bio:~/temp$ cat /boot/initrd.img-2.6.22.19-lustre-686.bak | gunzip | cpio -i
    27903 block
    bio:~/temp$ cd ../temp2
    bio:~/temp2$ cat /boot/initrd.img-2.6.22.19-lustre-686 | gunzip | cpio -i
    28313 blockss
    bio:~/temp2$ cd ..
    bio:~$ diff -r temp temp2
    只在 temp2/lib 存在：firmware
    只在 temp2/lib/udev 存在：firmware.agent
    bio:~$ ls temp2/lib/firmware/
    bnx2-06-4.0.5.fw  bnx2-09-4.0.5.fw
    bio:~$ cat temp2/lib/udev/firmware.agent 
    

    #!/bin/sh -e
    #
    # firmware loader agent
    #
    
    cd /lib/udev/
    . ./hotplug.functions
    
    if [ ! -e /sys/$DEVPATH/loading ]; then
        mesg "/sys/$DEVPATH/ does not exist"
        exit 1
    fi
    
    for DIR in $FIRMWARE_DIRS; do
        [ -e "$DIR/$FIRMWARE" ] || continue
        echo 1 > /sys/$DEVPATH/loading
        cat "$DIR/$FIRMWARE" > /sys/$DEVPATH/data
        echo 0 > /sys/$DEVPATH/loading
        exit 0
    done
    
    # the firmware was not found
    echo -1 > /sys/$DEVPATH/loading
    
    debug_mesg "Cannot find the $FIRMWARE firmware"
    exit 1
    

  • 其中 firmware.agent 是屬於 udev 套件

    bio:~$ dpkg -S firmware.agent
    udev: /lib/udev/firmware.agent
