• [陽明] 發現 Lustre 有問題，疑似與安裝 VirtualBox 2.2 的 kernel module 有關。(因為重編 Kernel)

  • [解法] 移除 VirtualBox，以 2.6.18-6-amd64 重開，移除並重新安裝 Lustre 核心套件

    $ sudo apt-get remove virtualbox2.2
    $ sudo apt-get remove --purge linux-image-2.6.22.19-lustre-amd64 lustre-modules-2.6.22.19-lustre-amd64
    $ sudo rm -rf /lib/modules/2.6.22.19-lustre-amd64
    $ sudo apt-get --reinstall install linux-image-2.6.22.19-lustre-amd64 lustre-modules-2.6.22.19-lustre-amd64
