在AIX 5L上配置NFS Server/Client(2)

关于mount的信息，是写在/etc/filesystems中的，如

#more /etc/filesystems

    ......
    /mydisk:
        dev             = "/disk1"
        vfs             = nfs
        nodename        = dbbak
        mount           = false
        type            = nfs3
        options         = soft,intr,retry=2,rsize=32768,wsize=32768,timeo=300,proto=tcp
        account         = false
    ......

其中nodename指定了服务器的名字，其对应的ip在/etc/hosts中体现，dev指定了服务器的export出来的目录。

关于更多的options的设置，可以查阅更多的nfs的文档。

其详细信息，也可以在smit中获得，如smit nfs–>Network File System (NFS) –>Add a File System for Mounting或者是Change / Show Attributes of an NFS File System。如

#smit chnfsmnt

    * PATHNAME of mount point                             /mydisk
    * PATHNAME of Remote Directory                       [/disk1]
    * HOST where remote directory resides                [dbbak]
      Mount type NAME                                    [nfs3]
    * Use SECURE mount option?                            no
    * Remount file system now,                            both
       update /etc/filesystems or both?
    * /etc/filesystems entry will mount the directory     no
       on system RESTART.
    * MODE for this NFS file system                       read-write

      Buffer SIZE for writes                             [32768]
      NFS TIMEOUT. In tenths of a second                 [300]
      NFS version for this NFS file system                any
      Transport protocol to use                           tcp
      Internet port NUMBER for server                    []
    * Allow execution of SUID and sgid programs           yes
       in this file system?
    * Allow DEVICE access via this mount?                 yes
    * Server supports long DEVICE NUMBERS?                yes
    * Mount file system soft or hard                      soft

验证 mountd、portmap 和 nfsd 守护程序正在 NFS 服务器上运行，请在客户机 shell 提示符下输入以下命令：

#/usr/bin/rpcinfo -u server_name mount

#/usr/bin/rpcinfo -u server_name portmap

#/usr/bin/rpcinfo -u server_name nfs

如果守护程序在服务器运行，会返回以下响应：

    program  100005  version  1  ready  and  waiting
    program  100000  version  2  ready  and  waiting
    program  100003  version  2  ready  and  waiting

程序号分别与命令对应，如前例中所示。如果没有返回类似的响应，请在服务器控制台上登录服务器并按照获取 NFS 守护程序的当前状态中的指示信息检查守护程序的状态。

#showmount -e server_name

该命令列出了由 server_name 当前导出的所有文件系统。

注意：如果在AIX上mount linux的nfs文件系统，可能需要特殊执行：
