如何理解AIX上mount NFS

本篇文章为大家展示了如何理解AIX上mount NFS，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

在AIX操作系统，所有的mount point信息都存储在文件 ：/etc/filesystems

When mount information is not present in this file it can lead to errors.

cat /etc/filesystems

/u08:

        dev             = "/vol/xxxx"

        vfs             = nfs

        nodename        = jq_xxxx_sata

        mount           = false       //表示是否开机自动挂载

        options         = bg,hard,intr,rsize=32768,wsize=32768,timeo=600,vers=3,sec=sys    //挂载参数

        account         = false

导出文件至NFS文件系统时报错：

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options

ORA-39001: invalid argument value

ORA-39000: bad dump file specification

ORA-31641: unable to create dump file "********"

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

Additional information: 5

Additional information: 18

原因：

nfs文件挂载参数配置不正确

分析：

查看/etc/filesystems

/u08:

        dev             = "/vol/backup"

        vfs             = nfs

        nodename        = jq_netapp_sata

        mount           = false

        options         = bg,hard,intr,rsize=32768,wsize=32768,timeo=600,vers=3,sec=sys

        account         = false

根据文件中写的参数手工挂载：

mount -o rw,bg,hard,intr,proto=tcp,vers=3,rsize=32768,wsize=32768,timeo=600 jq_netapp_sata:/vol/backup /u08

此类问题的官方解决方案罗列如下：

SOLUTION 

=========

To implement the solution, please execute one the following steps:

1. Don't use NFS to create the  files.

Or

2. Add the NFS filesys to '/etc/filesystems' 

--> This is also applicable for 11G

Or

3. Edit init.ora, add the line:

    event="10298 trace name context forever, level 32"    \\此方法需重启数据库

and bounce the database again, if it already exist so that the new parameter is active.
