NFS export from AIX HACMP CLUSTER

Do NFS export from AIX HACMP CLUSTER to Linux server

Scenario: Export /hacmp/export from aixhanode1 to linux host linuxnode1 and linuxnode2

On PowerHA-cluster /usr/es/sbin/cluster/etc/exports is used for exporting filesystems.

Step 1: For Cluster setup while doing NFS export from Cluster node edit file /usr/es/sbin/cluster/etc/exports . Don’t use /etc/exports file, /etc/exports file used in NON-CLUSTER environment.

Step 2:

Find export directory stanza and add hostname to whom directory need to export.

Here find stanza "/hacmp/export" and add client name at last without affecting current hostname list.

Example:

Find stanza for /hacmp/export in file /usr/es/sbin/cluster/etc/exports and add hostname linuxnode1 linuxnode2 and save file

Vi /usr/es/sbin/cluster/etc/exports

/hacmp/export -rw,root=linuxnode1:linuxnode2

Step3:

Execute following command to activate changes which we made in file /usr/es/sbin/cluster/etc/exports , by executing following command.

exportfs -a -f /usr/es/sbin/cluster/etc/exports

Step 4 :

Check on both client whether NFS directory is exported or not by using below command

showmount -e nfsservername

showmount –e aixhanode1

Step 5:

Mount share directory using mount command.

Mount aixhanode1:/hacmp/export /mnt      //mounting on temp mount point

Mount aixhanode1:/hacmp/export /mnt

       Or you also mount on same name mount point using below command.

Before executing make sure that /hacmp/export exist on both NFS client.

Mount aixhanode1:/hacmp/export  /hacmp/export

Mount aixhanode1:/hacmp/export  /hacmp/export

Verify whether directory/FS is mounted or not by executing below command.

df –hT /hacmp/export

Thanks!!!
