AIX学习之--文件系统修复（/home)

系统环境：

操作系统：AIX 5.3.8

Oracle:  Oracle 10gR2

案例：

在执行mount文件系统时出现以下错误：

[root@aix199:/]#mount /home

Replaying log for /dev/hd1.

Devices already mounted that are using /dev/hd8

Failure replaying log: 0

mount: /dev/hd1 on /home: Unformatted or incompatible media

The superblock on /dev/hd1 is dirty.  Run a full fsck to fix.
