aix 7 挂载LINUX下NFS


目的是备份数据库;又没与多余的硬盘空间,想挂载LINUX下的NFS 来实现;把步骤记录下来,供参考:


一、在LINUX 下把NFS 搭建完成;

[root@hostback ~]# rpm -qa |grep nfs
nfs-utils-lib-1.0.8-7.9.el5
nfs-utils-1.0.9-60.el5


[root@hostback CentOS]# pwd
/home/install_source/cdsorce/CentOS


[root@hostback CentOS]# ls nfs*
nfs4-acl-tools-0.3.3-3.el5.x86_64.rpm
nfs-utils-1.0.9-60.el5.x86_64.rpm
nfs-utils-lib-1.0.8-7.9.el5.i386.rpm
nfs-utils-lib-1.0.8-7.9.el5.x86_64.rpm
nfs-utils-lib-devel-1.0.8-7.9.el5.i386.rpm
nfs-utils-lib-devel-1.0.8-7.9.el5.x86_64.rpm

[root@hostback CentOS]# rpm -ivh nfs4-acl-tools-0.3.3-3.el5.x86_64.rpm
warning: nfs4-acl-tools-0.3.3-3.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

[root@hostback CentOS]# rpm -ivh nfs-utils-lib-devel-1.0.8-7.9.el5.x86_64.rpm

[root@hostback CentOS]# df -h

/dev/sda3              67G  4.5G   59G   8% /
/dev/sda5              20G  4.5G   14G  25% /home
/dev/sda2             436G  199M  414G   1% /dbbak  //要把该目录挂载到AIX下;
/dev/sda1              99M   12M   82M  13% /boot

/dev/hda              4.3G  4.3G     0 100% /mnt/cdrom



[root@hostback ~]# vi /etc/exports       

/dbbak/   192.168.80.0/24(rw,no_root_squash)


 然后重新启动NFS服务器,现在我们的SELINUX是强制状态,iptablesinput和output都是默认ACCEPT,由于NFS服务是基于portmap服务的,所以我们需要先启动portmap服务:service portmap restart ,然后 service nfs restart  使用showmount 指令看看是否共享成功showmount -e  后面跟你的服务器IP

[root@hostback ~]# showmount -e 192.168.80.98
Export list for 192.168.80.98:
/dbbak 192.168.80.0/24


[root@hostback /]# df -h

/dev/hda              4.3G  4.3G     0 100% /mnt/cdrom
[root@hostback /]#


[root@hostback ~]# mount -t nfs 192.168.80.98:/dbbak /mnt/nfs     //自己当作客户端挂载自己nfs 目录要新建

[root@hostback /]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              67G  4.5G   59G   8% /

192.168.80.98:/dbbak  436G  198M  414G   1% /mnt/nfs           //已经有了


二、登录AIX ,

1、挂在linux nfs

root@ptdb1:/# mount 192.168.80.98:/dbbak /rmanbak
mount: 1831-008 giving up on:
192.168.80.98:/dbbak
vmount: Operation not permitted.


root@ptdb1:/# nfso -a | grep nfs_use_reserved_ports
      nfs_use_reserved_ports = 0

默认情况,AIX系统执行mount命令请求时并不使用预先定义好的端口,设置nfs_use_reserved_ports后可使用1024以下的预定义端口


root@ptdb1:/# nfso -o nfs_use_reserved_ports=1
Setting nfs_use_reserved_ports to 1
root@ptdb1:/#
root@ptdb1:/# nfso -a | grep nfs_use_reserved_ports
      nfs_use_reserved_ports = 1
root@ptdb1:/# mount -v nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,nointr,timeo=600,proto=tcp 192.168.80.98:/backdata   /rmanbak      //这样AIX 就可以正确挂载Linux 的nfs 共享文件了 


root@ptdb1:/# df -g

root@ptdb1:/rmanbak# mount

192.168.80.98 /dbbak           /rmanbak         nfs3   Jun 09 21:51           


2、使用smitty nfs ,创建NFS文件系统,或者直接在/etc/filesystems后面有添加如下显示:


/home/oracle/rmanbak:
        dev             = /backdata
        vfs             = nfs
        nodename        = 192.168.80.98
        mount           = true
        options         =  rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,vers=3,timeo=600
        account         = false
