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

[root@hostback CentOS]# df -h

[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

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

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
