How to Configure the File System on the Primary Cluster for the NFS Application

Before You Begin

Ensure that you completed steps in How to Configure a Disk Device Group on the Secondary Cluster.

Steps

1. On nodeA and nodeB, create a mount point directory for the NFS file system.

   For example:

   nodeA# mkdir /global/mountpoint

2. On nodeA and nodeB, configure the master volume to be mounted automatically on the mount point.

   Add or replace the following text to the /etc/vfstab file on nodeA and nodeB. The text must be on a single line.

   /dev/vx/dsk/devicegroup/vol01 /dev/vx/rdsk/devicegroup/vol01 \ /global/mountpoint ufs 3 no global,logging

   For a reminder of the volumes names and volume numbers used in the disk device group, see Figure 6–8.

3. On nodeA, create a volume for the file system information that is used by the Sun Cluster HA for NFS data service.

   nodeA# /usr/sbin/vxassist -g devicegroup make vol05 120m disk1

   Volume 5, vol05, contains the file system information that is used by the Sun Cluster HA for NFS data service.

4. On nodeA, resynchronize the device group with the Sun Cluster software.

   nodeA# /usr/cluster/bin/scconf -c -D name=devicegroup,sync

5. On nodeA, create the file system for vol05.

   nodeA# /usr/sbin/newfs /dev/vx/rdsk/devicegroup/vol05

6. On nodeA and nodeB, create a mount point for vol05.

   For example:

   nodeA# mkdir /global/etc

7. On nodeA and nodeB, configure vol05 to be mounted automatically on the mount point.

   Add or replace the following text to the /etc/vfstab file on nodeA and nodeB. The text must be on a single line.

   /dev/vx/dsk/devicegroup/vol05 /dev/vx/rdsk/devicegroup/vol05 \ /global/etc ufs 3 yes global,logging

8. Mount vol05 on nodeA.

   nodeA# mount /global/etc

9. Make vol05 accessible to remote systems.

   1. Create a directory called /global/etc/SUNW.nfs on nodeA.

      nodeA# mkdir -p /global/etc/SUNW.nfs

   2. Create the file /global/etc/SUNW.nfs/dfstab.nfs-rs on nodeA.

      nodeA# touch /global/etc/SUNW.nfs/dfstab.nfs-rs

   3. Add the following line to the /global/etc/SUNW.nfs/dfstab.nfs-rs file on nodeA:

      share -F nfs -o rw -d "HA NFS" /global/mountpoint
