安装GlusterFS客户端时，rpm正常安装没有任何报错，但是挂载时不成功，终端上没有任何提示，/var/log/gluster/下却又报错提示：

追其原因，是因为内核没有装载fuse模块。解决方案如下：
rpm –import http://apt.sw.be/RPM-GPG-KEY.dag.txt
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
rpm -ivh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
yum install dkms dkms-fuse

执行 modprobe fuse 确认fuse是否加载，如果正常的话不会有任何输出。

问题解决，重新挂载成功。

今天回家后，发现公司的一台服务器关了，于是想是否可以远程唤醒…… 虽然不知道主板配置是否支持远程唤醒，但还是试一下吧！

1. 下载 wake up 源代码
wget http://openixp.devel.phj.hu/cgi-bin/trac.cgi/export/98/package/ether-wake/files/ether-wake.c

2. 编译源代码
gcc -O -Wall -o ether-wake ether-wake.c

3. 制定MAC地址开始远程唤醒
其实远程唤醒的关键是怎么找到要唤醒的主机的MAC地址。呵呵～～我到DHCP服务器上找到了！！
./ether-wake  40:61:86:7c:36:xx

4. 一会儿，我在交换机上display arp 时，发现了期待已久的IP 和 MAC.

 很幸运，主板配置是支持远程唤醒的。
