Fucq硬盘维护完成

本次错误发生在两周前，C=1,I=6硬盘Failure,由于C=1,I=4上坏块的存在，无法启用热备盘rebuild. 解决方法是完全备份了C=1,然后删除C=1,移除C=1,I=6,然后重新配置了C=1。目前
/software, /database 已经恢复正常，/backup完全丢失。

ERROR:C=1 I=4 badblock found

Again,the array reports a badblock on C=1,I=4, with no beep. I am not sure how serious this problem is. After enter pressed, the attention disappears.

几点设想

现在的 FucQ 已经基本配置完成。下面是一些管理设想，供后面参考实现：

1. 将构建在 NIS 上的用户信息迁移到 LDAP 上，优势是不言而喻的。
2. 设置好一个足够合理的 iptables，这点应该尽快完成。
3. 对用户使用磁盘情况进行监管，激活 quota。现在需要重启一次机器才可能实现。
4. 进一步配置好 FAI，便于以后实验室内部安装新的 Linux 主机。

Currely FucQ has been configured with several basic functions. Here list more measures for future management:

1. Transport information of user accounts now managed by NIS to LDAP. There are several apparent advantages of LDAP over NIS.
2. Design a reasonable iptables, which is urgent and indispensible.
3. Check the disk usage of all users by activating quota, which needs a reboot of FucQ.
4. Configure FAI for installing new Linux hosts in our lab.
