Configuring all NFS services in a parallel service group

Use this configuration when you want only the NFS service to run. If you want any of the functionality provided by the NFSRestart agent, do not use this configuration. This configuration has some disadvantages because it does not support NFS lock recovery and it does not prevent potential NFS ACK storms. Symantec does not recommend this configuration.

Creating the NFS service group

This service group contains an NFS resource and an NFSRestart resource.

To create the NFS service group

  1. Configure a separate parallel service group (nfs_grp).
  2. Set the value of the AutoStart and Parallel attributes to 1 for the service group. The value for the AutoStartList must contain the list of all the cluster nodes in the service group.
  3. Configure an NFS resource (nfs) inside this service group. You can also put NIC resource in this service group to monitor a NIC.
  4. Configure an NFSRestart resource inside this service group. Set the value of Lower attribute to 2. The NFSRes attribute of this resource must point to the NFS resource (nfs) configured on the system. NFSLockFailover is not supported in this configuration.

Note:

  • NFSLockFailover is not supported in this configuration.

  • This configuration does not prevent potential NFS ACK storms.

  • NFSv4 is not supported in this configuration.

Creating the NFS exports service group

This service group contains the Share and IP resources for exports. The value for the PathName attribute for the Share resource must be on shared storage and it must be visible to all nodes in the cluster.

To create the NFS exports service group

  1. Create an NFS Proxy resource inside the service group. This Proxy resource points to the actual NFS resource that is configured on the system.
  2. If you configure the backing store for the NFS exports with VxVM, create DiskGroup and Mount resources for the mount point that you want to export.

    If the backing store for the NFS exports is configured using LVM, configure the LVMVolumeGroup plus the Mount resources for the mount point that you want to export.

    Refer to Storage agents chapter of the Symantec Cluster Server Bundled Agents Reference Guide for details.

  3. Create a Share resource. Set the PathName to the mount point that you want to export. In case of multiple shares, create multiple Share resources with different values for their PathName attributes.
  4. Create an IP resource. The value of the Address attribute for this IP resource is used to mount the NFS exports on the client systems. Make the IP resource depend on the Share resources that are configured in the service group.
