AIX学习之--文件系统修复（/home)

来源：互联网发布：three.js 性能编辑：程序博客网时间：2024/05/16 07:59

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.

fsck修复文件系统：

[root@aix199:/]#fsck -y /home

重新mount文件系统：

[root@aix199:/]#mount /home[root@aix199:/]#ls /homeTT_DB       dba         guest       lost+found  oracle

执行sqlplus命令出错：

[oracle@aix199:~]$sqlplus

Could not load program sqlplus:

Cannot run a 64-bit program until the 64-bit

environment has been configured. See the system administrator.

查看系统内核版本：

[root@aix199:/]#bootinfo -K

查看系统信息：

[root@aix199:/]#prtconf |more

系统内核应该为64位，所以重新启动系统，系统重启后问题解决！
