Mounting NFS From Linux To AIX

Mounting NFS From Linux To AIX

Linux Box (192.168.1.99)

1. SSH to the Linux box
2. Add an entry in the /etc/hosts to add the AIX server IP and hostname, if it is not already there
3. Specify the file system to be exported in the /etc/exports file
   /data 192.168.1.100 
4. Start the nfs service, if it has not already been started
   [root@linux ~]# service nfs status
   rpc.mountd (pid 3170) is running…
   nfsd (pid 3167 3166 3165 3164 3163 3162 3161 3160) is running…
   rpc.rquotad (pid 3145) is running…
   [root@linux ~]# service nfs restart
   Shutting down NFS mountd: [ OK ]
   Shutting down NFS daemon: [ OK ]
   Shutting down NFS quotas: [ OK ]
   Shutting down NFS services: [ OK ]
   Starting NFS services: [ OK ]
   Starting NFS quotas: [ OK ]
   Starting NFS daemon: [ OK ]
   Starting NFS mountd: [ OK ]
5. Run the exportfs command to export the file system
   # exportfs -a

AIX Box (192.168.1.100)

1. Add an entry in the /etc/hosts for the Linux box, if it is not already there.
2. Run the showmount command to check if AIX can see the exported file system
   # showmount -e 192.168.1.100 
3. Create a directory to mount the NFS
   # mkdir /data 
4. Run the mount command to mount the exported NFS
   # mount 192.168.1.99:/data /data 
5. If not able to mount and the error message is "vmount: operation not permitted", run the command below. Detailed explanation here.
   #  nfso -p -o nfs_use_reserved_ports=1
6. Try the mount command again.
7. If successful, try to access the directory.
