AIX學(xué)習(xí)之--文件系統(tǒng)修復(fù)（/home)

系統(tǒng)環(huán)境：

操作系統(tǒng)：AIX 5.3.8

Oracle:  Oracle 10gR2

案例：

在執(zhí)行mount文件系統(tǒng)時出現(xiàn)以下錯誤：

[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.
